Update to 2.19.5: * Fix multiple Denial of service attacks due to X.509 cert processing: * CVE-2024-34702 - bsc#1227238 * CVE-2024-34703 - bsc#1227607 * CVE-2024-39312 - bsc#1227608 * Fix a crash in OCB * Fix a test failure in compression with certain versions of zlib * Fix some iterator debugging errors in TLS CBC decryption. * Avoid a miscompilation in ARIA when using XCode 14- Update to 2.19.3: * validate that an embedded certificate was issued by the end-entity issuing certificate authority when checking OCSP responses. * CVE-2022-43705 * bsc#1205509- update to 2.19.2: * Add support for parallel computation in Argon2 * Add SSSE3 implementation of Argon2 * The OpenSSL provider was incompatible with OpenSSL 3.0. It has been removed * Avoid using reserve in secure_vector appending, which caused a performance problem * Fix TLS::Text_Policy behavior when X25519 is disabled at build time * Fix several warnings from Clang- update to 2.19.1: * Add a forward error correction code compatible with the zfec library- update to 2.18.2: * Avoid using short exponents when encrypting in ElGamal, as some PGP implementations generate keys with parameters that are weak when short exponents are used CVE-2021-40529 boo#1190244 * Fix a low risk OAEP decryption side channel * Work around a miscompilation of SHA-3 caused by a bug in Clang 12 and XCode 13 * Remove support in OpenSSL provider for algorithms which are disabled by default in OpenSSL 3.0 * Add CI based on GitHub actions to replace Travis CI * Fix the online OCSP test, as the certificate involved had expired. * Fix some test failures induced by the expiration of the trust root "DST Root CA X3"- Botan 2.18.1: * Fix a build regression in 2.18.0 which caused linker flags which contain -l within them (such as -fuse-linker-plugin) to be misinterpreted * Fix a bug which caused decoding a certificate which contained more than one name in a single RDN * Fix a bug which caused OID lookup failures when run in a locale which uses thousands separators (pt_BR was reported as having this issue) * DNS names in name constraints were compared with case sensitivity, which could cause valid certificates to be rejected * X.509 name constraint extensions were rejected if non-critical. RFC 5280 requires conforming CAs issue such extensions as critical, but not all certificates are compliant, and all other known implementations do not require this * X.509 name constraints were incorrectly applied to the certificate which included the constraint - build with lzma compression support - build with SQLite support - build with TPM support - fix SLE 12 build- Botan 2.18.0 * Add support for implementing custom RNG objects through the FFI interface * Improve safegcd bounds, improving runtime performance * Reject non-TLS messages as quickly as possible without waiting for a full record. * Fixes for TLS::Stream::async_shutdown - Removed unneeded GNU MP build requirement, support was dropped with version 1.11.10 - Enabled check target, verify integrity of build library- Botan 2.17.3: * Harden against side-channels from decoding secret values by changing the base64, base58, base32, and hex encoding and decoding opearations to run in constant time- Botan 2.17.2: * Fix build problem on ppc64 * Resolve an issue in the modular square root algorithm- Botan 2.17.1: * Fix bugs in ECDSA signature generation and verifications under specific circumstances * developer visible changes, including deprecation with warnings * optimization in the non-hardware assisted AES key generation * Add more detection logic for AVX-512 features * Fix a bug parsing deeply nested cipher names * Prevent requesting DER encoding of signatures when the algorithm did not support it- Update to 2.16.0: * Now userspace PRNG objects (such as AutoSeeded_RNG and HMAC_DRBG) use an internal lock, which allows safe concurrent use. This however is purely a precaution in case of accidental sharing of such RNG objects; for performance reasons it is always preferable to use a RNG per thread if a userspace RNG is needed. * DL_Group and EC_Group objects now track if they were created from a known trusted group (such as P-256 or an IPsec DH parameter). If so, then verification tests can be relaxed, as compared to parameters which may have been maliciously constructed in order to pass primality checks. * RandomNumberGenerator::add_entropy_T assumed its input was a POD type but did not verify this. * Support OCSP responders that live on a non-standard port. * Add support for Solaris sandbox. * Support suffixes on release numbers for alpha/beta releases. * Fix a bug in EAX which allowed requesting a 0 length tag, which had the effect of using a full length tag. Instead omit the length field, or request the full tag length explicitly. * Fix a memory leak in GCM where if passed an unsuitable block cipher (eg not 128 bit) it would throw an exception and leak the cipher object.- update to 2.15: Fix a bug where the name constraint extension did not constrain the alternative DN field which can be included in a subject alternative name. This would allow a corrupted sub-CA which was otherwise constrained by a name constraint to issue a certificate with a prohibited DN. Fix a bug in the TLS server during client authentication where where if a (disabled by default) static RSA ciphersuite was selected, then no certificate request would be sent. This would have an equivalent effect to a client which simply replied with an empty Certificate message. (GH #2367) Replace the T-Tables implementation of AES with a 32-bit bitsliced version. As a result AES is now constant time on all processors. (GH #2346 #2348 #2353 [#2329] #2355) In TLS, enforce that the key usage given in the server certificate allows the operation being performed in the ciphersuite. (GH #2367) In X.509 certificates, verify that the algorithm parameters are the expected NULL or empty. (GH #2367) Change the HMAC key schedule to attempt to reduce the information leaked from the key schedule with regards to the length of the key, as this is at times (as for example in PBKDF2) sensitive information. (GH #2362) Add Processor_RNG which wraps RDRAND or the POWER DARN RNG instructions. The previous RDRAND_RNG interface is deprecated. (GH #2352) The documentation claimed that mlocked pages were created with a guard page both before and after. However only a trailing guard page was used. Add a leading guard page. (GH #2334) Add support for generating and verifying DER-encoded ECDSA signatures in the C and Python interfaces. (GH #2357 #2356) Workaround a bug in GCC’s UbSan which triggered on a code sequence in XMSS (GH [#2322]) When building documentation using Sphinx avoid parallel builds with version 3.0 due to a bug in that version (GH #2326 #2324) Fix a memory leak in the CommonCrypto block cipher calls (GH #2371) Fix a flaky test that would occasionally fail when running the tests with a large number of threads. (GH #2325 #2197) Additional algorithms are now deprecated: XTEA, GOST, and Tiger. They will be removed in a future major release.- Update to Botan 2.14: * Add support for using POWER8+ VPSUMD instruction to accelerate GCM (GH #2247) * Optimize the vector permute AES implementation, especially improving performance on ARMv7, Aarch64, and POWER. (GH #2243) * Use a new algorithm for modular inversions which is both faster and more resistant to side channel attacks. (GH #2287 #2296 #2301) * Address an issue in CBC padding which would leak the length of the plaintext which was being padded. Unpadding during decryption was not affected. * Optimize NIST prime field reductions, improving ECDSA by 3-9% (GH #2295) * Increase the size of the ECC blinding mask and scale it based on the size of the group order. (GH #880 #893 #2308) * Add server side support for the TLS asio wrapper. (GH #2229) * Add support for using Windows certificate store on MinGW (GH #2280) * Add a CLI utility cpu_clock which estimates the speed of the processor cycle counter. * Add Roughtime client (GH #2143 #1842) * Add support for XMSS X.509 certificates (GH #2172) * Add support for X.509 CRLs in FFI layer and Python wrapper (GH #2213) * Add AVX2 implementation of SHACAL2 (GH #2196) * Support more functionality for X.509 in the Python API (GH #2165) * Add generic CPU target useful when building for some new or unusual platform. * Disable MD5 in BSI or NIST modes (GH #2188) * Many currently public headers are being deprecated. If any such header is included by an application, a warning is issued at compile time. Headers issuing this warning will be made internal in a future major release. * RSA signature performance improvements (GH #2068 #2070) * Performance improvements for GCM (GH #2024 #2099 #2119), OCB (#2122), XTS (#2123) and ChaCha20Poly1305 (GH #2117), especially for small messages. * Add support for constant time AES using NEON and AltiVec (GH #2093 #2095 #2100) * Improve performance of POWER8 AES instructions (GH #2096) * Add support for the POWER9 hardware random number generator (GH #2026) * Add support for 64-bit version of RDRAND, doubling performance on x86-64 (GH #934 #2022) * In DTLS server, support a client crashing and then reconnecting from the same source port, as described in RFC 6347 sec 4.2.8 (GH #2029) * Optimize DTLS MTU splitting to split precisely to the set MTU (GH #2042) * Add support for the TLS v1.3 downgrade indicator. (GH #2027) * Add Argon2 PBKDF and password hash (GH #459 #1981 #1987) * Add Bcrypt-PBKDF (GH #1990) * Add server side support for issuing DTLS HelloVerifyRequest messages (GH #1999) * Add support for the TLS v1.3 supported_versions extension. (GH #1976) * Add Ed25519ph compatible with RFC 8032 (GH #1699 #2000) * Add support for OCSP stapling on server side. (GH #1703 #1967) * Add a boost::asio TLS stream compatible with boost::asio::ssl. (GH #1839 #1927 #1992) * Add a certificate store for Linux/Unix systems. (GH #1885 #1936) * Various Fixes- Update to Botan 2.10 * Bump SONAME * Warning: XMSS currently implements draft-06 which is not compatible with the final RFC 8391 specification. A PR is open to fix this, however it will break all current uses of XMSS. If you are currently using XMSS please comment at https://github.com/randombit/botan/pull/1858. Otherwise the PR will be merged and support for draft-06 will be removed starting in 2.11. * Added a new certificate store implementation that can access the MacOS keychain certificate store. (GH #1830) * Redesigned Memory_Pool class, which services allocations out of a set of pages locked into memory (using mlock/VirtualLock). It is now faster and with improved exploit mitigations. (GH #1800) * Add BMI2 implementations of SHA-512 and SHA-3 which improve performance by 25-35% on common CPUs. (GH #1815) * Unroll SHA-3 computation improving performance by 10-12% (GH #1838) * Add a Thread_Pool class. It is now possible to run the tests in multiple threads with --test-threads=N flag to select the number of threads to use. Use --test-threads=0 to run with as many CPU cores as are available on the current system. The default remains single threaded. (GH #1819) * XMSS signatures now uses a global thread pool instead of spawning new threads for each usage. This improves signature generation performance by between 10% and 60% depending on architecture and core count. (GH #1864) * Some functions related to encoding and decoding BigInts have been deprecated. (GH #1817) * Binary encoding and decoding of BigInts has been optimized by performing word-size operations when possible. (GH #1817) * Rename the exception Integrity_Failure to Invalid_Authentication_Tag to make its meaning and usage more clear. The old name remains as a typedef. (GH #1816) * Support for using Boost filesystem and MSVC’s std::filesystem have been removed, since already POSIX and Win32 versions had to be maintained for portability. (GH #1814) * Newly generated McEliece and XMSS keys now default to being encrypted using SIV mode, support for which was added in 2.8.0. Previously GCM was used by default for these algorithms. * Use arc4random on Android systems (GH #1851) * Fix the encoding of PGP-S2K iteration counts (GH #1853 #1854) * Add a facility for sandboxing the command line util. Currently FreeBSD (Capsicum) and OpenBSD (pledge) sandboxes are supported. (GH #1808) * Use if constexpr when available. * Disable building shared libs on iOS as it was broken and it is not clear shared libraries are ever useful on iOS (GH #1865) * Renamed the darwin build target to macos. This should not cause any user-visible change. (GH #1866) * Add support for using sccache to cache the Windows CI build (GH #1807) * Add --extra-cxxflags option which allows adding compilation flags without overriding the default set. (GH #1826) * Add --format= option to the hash cli which allows formatting the output as base64 or base58, default output remains hex. * Add base58_enc and base58_dec cli utils for base58 encoding/decoding. (GH #1848) * Enable getentropy by default on macOS (GH #1862) * Avoid using -momit-leaf-frame-pointer flags, since -fomit-frame-pointer is already the default with recent versions of GCC. * Fix XLC sanitizer flags. * Rename Blake2b class to BLAKE2b to match the official name. There is a typedef for compat. * Fix a bug where loading a raw Ed25519_PublicKey of incorrect length would lead to a crash.

Now with these modes setting an AD after beginning a message throws an exception. * Use a smaller sieve which improves performance of prime generation. * Fixed a bug that caused ChaCha to produce incorrect output after encrypting 256 GB. (GH #1728) * Add NEON and AltiVec implementations of ChaCha (GH #1719 #1728 #1729) * Optimize AVX2 ChaCha (GH #1730) * Many more operations in BigInt, ECC and RSA code paths are either fully const time or avoid problematic branches that could potentially be exploited in a side channel attack. (GH #1738 #1750 #1754 #1755 #1757 #1758 #1759 #1762 #1765 [#1770] #1773 #1774 #1779 #1780 #1794 #1795 #1796 #1797) * Several optimizations for BigInt and ECC, improving ECDSA performance by as much as 30%.

This avoids issues with fork. (GH #602 #1798) * When available, use RDRAND to generate the additional data in Stateful_RNG::randomize_with_ts_input * Use vzeroall/vzeroupper intrinsics to avoid AVX2/SSE transition penalties. * Support for Visual C++ 2013 has been removed (GH #1557 #1697) * Resolve a memory leak when verifying ECDSA signatures with versions of OpenSSL before 1.1.0 (GH #1698) * Resolve a memory leak using ECDH via OpenSSL (GH #1767) * Fix an error in XTS which prohibited encrypting values which were exactly the same length as the underlying block size. Messages of this size are allowed by the standard and other XTS implementations. (GH #1706) * Resolve a bug in TSS which resulted in it using an incorrect length field in the shares. Now the correct length is encoded, but either correct or buggy lengths are accepted when decoding. (GH #1722) * Correct a bug when reducing a negative BigInt modulo a small power of 2.

(GH #1268) * Modify configure.py to accept empty lists or trailing/extra commas. (GH #1705) - Update to Botan 2.8 * Add support for using Apple CommonCrypto library for hashing (GH #1667), cipher modes (GH #1674) and block ciphers (GH #1673). * Support for negotiating TLS versions 1.0 and 1.1 is disabled in the default TLS policy. In addition, support for negotiating TLS ciphersuites using CBC or CCM mode is disabled by default. Applications which need to interop with old peers must enable these in their TLS policy object. (GH #1651) * During primality testing, use a Lucas test in addition to Miller-Rabin. It is possible to construct a composite integer which passes n Miller-Rabin tests with probability (1/4)^n. So for a incautious verifier using a small number of tests (under 16 or so) it is possible if unlikely they would accept such a composite as prime. Adding a Lucas test precludes such an attack. (GH #1636) * Add XChaCha and XChaCha20Poly1305 (GH #1640) * Add AVX2 implementations of ChaCha (GH #1662) and Serpent (GH #1660) * Add a new password hashing interface in pwdhash.h (GH #1670) * C binding improvements.

They have now been merged into a single key type since in practice it seems the same key is at times used for both operations. (GH [#1637]) * The Cipher_Mode class now derives from SymmetricAlgorithm (GH #1639) * Add support for using the ARMv8 instructions for SM4 encryption (GH #1622) * The entropy source using SecRandomCopyBytes has been removed as it was redundant with other entropy sources (GH #1668) * The Python module has much better error checking and reporting, and offers new functionality such as scrypt, MPI and FPE.

(GH #1564) * Unroll Montgomery reduction for specific sizes (GH #1603) * Improved performance of signature verification in ECGDSA, ECKCDSA, SM2 and GOST by 10-15%. * XMSS optimizations (GH #1583 #1585) * Fix an error that meant XMSS would only sign half as many signatures as is allowed (GH #1582) * Add support for base32 encoding/decoding (GH #1541) * Add BMI2 optimized version of SHA-256, 40% faster on Skylake (GH #1584) * Allow the year to be up to 2200 in ASN.1 time objects. Previously this was limited to 2100. (GH #1536) * Add support for Scrypt password hashing (GH #1570) * Add support for using Scrypt for private key encryption (GH #1574) * Optimizations for DES/3DES, approx 50% faster when used in certain modes such as CBC decrypt or CTR. * XMSS signature verification did not check that the signature was of the expected length which could lead to a crash. (GH #1537) * The bcrypt variants 2b and 2y are now supported. * Support for 192-bit Suite B TLS profile is now implemented, as the 128-bit Suite B is since 2015 not allowed anymore. * Previously botan allowed GCM to be used with an empty nonce, which is not allowed by the specification. Now such nonces are rejected. * Avoid problems on Windows when compiling in Unicode mode (GH #1615 #1616) * Previously for ASN.1 encoded signatures (eg ECDSA) Botan would accept any valid BER encoding. Now only the single valid DER encoding is accepted. * Correct an error that could in rare cases cause an internal error exception when doing computations with the P-224 curve. * Optimizations to reduce allocations/copies during DER encoding and BER decoding (GH #1571 #1572 #1600) * Botan generates X.509 subject key IDs by hashing the public key with whatever hash function is being used to sign the certificate. However especially for SHA-512 this caused SKIDs that were far longer than necessary. Now all SKIDs are truncated to 192 bits. * In the test suite use mkstemp to create temporary files instead of creating them in the current working directory. (GH #1533 #1530) * It is now possible to safely override CXX when invoking make in addition to when configure.py is run. (GH #1579) * OIDs for Camellia and SM4 in CBC and GCM mode are now defined, making it possible to use this algorithms for private key encryption. * Avoid creating symlinks to the shared object on OpenBSD (#1535) * The factor command runs much faster on larger inputs now. * Support for Windows Phone/UWP was deprecated starting in 2.5. This deprecation has been reversed as it seems UWP is still actively used. (GH [#1586] #1587) * Support for Visual C++ 2013 is deprecated, and will be removed in Jan 2019. * Added support for GCC’s –sysroot option to configure.py for cross-compiling.- fixed to build on armv6 and armv7- Update to Botan 2.6 * CVE-2018-9860 Fix a bug decrypting TLS CBC ciphertexts which could for a malformed ciphertext cause the decryptor to read and HMAC an additional 64K bytes of data which is not part of the record. This could cause a crash if the read went into unmapped memory. No information leak or out of bounds write occurs. * Add support for OAEP labels (GH #1508) * RSA signing is about 15% faster (GH #1523) and RSA verification is about 50% faster. * Add exponent blinding to RSA (GH #1523) * Add Cipher_Mode::create and AEAD_Mode::create (GH #1527) * Fix bug in TLS server introduced in 2.5 which caused connection to fail if the client offered any signature algorithm not known to the server (for example RSA/SHA-224). * Fix a bug in inline asm that would with GCC 7.3 cause incorrect computations and an infinite loop during the tests. (GH #1524 #1529)- Update to Botan 2.5 * Fix error in certificate wildcard matching (CVE-2018-9127), where a wildcard cert for b*.example.com would be accepted as a match for any host with name *b*.example.com (GH #1519) * Add support for RSA-PSS signatures in TLS (GH #1285) * Ed25519 certificates are now supported (GH #1501) * Many optimizations in ECC operations. ECDSA signatures are 8-10 times faster. ECDSA verification is about twice as fast. ECDH key agreement is 3-4 times faster. (GH #1457 #1478) * Implement product scanning Montgomery reduction, which improves Diffie-Hellman and RSA performance by 10 to 20% on most platforms. (GH [#1472]) * DSA signing and verification performance has improved by 30-50%. * Add a new Credentials_Manager callback that specifies which CAs the server has indicated it trusts (GH #1395 fixing #1261) * Add new TLS::Callbacks methods that allow creating or removing extensions, as well as examining extensions sent by the peer (GH #1394 #1186) * Add new TLS::Callbacks methods that allow an application to negotiate use of custom elliptic curves. (GH #1448) * Add ability to create custom elliptic curves (GH #1441 #1444) * Add support for POWER8 AES instructions (GH #1459 #1393 #1206) * Fix DSA/ECDSA handling of hashes longer than the group order (GH #1502 [#986]) * The default encoding of ECC public keys has changed from compressed to uncompressed point representation. This improves compatability with some common software packages including Golang’s standard library. (GH #1480 [#1483]) * It is now possible to create DNs with custom components. (GH #1490 #1492) * It is now possible to specify the serial number of created certificates, instead of using the default 128-bit random integer. (GH #1489 #1491) * Change DL_Group and EC_Group to store their data as shared_ptr for fast copying. Also both classes precompute additional useful values (eg for modular reductions). (GH #1435 #1454) * Make it possible for PKCS10 requests to include custom extensions. This also makes it possible to use muliple SubjectAlternativeNames of a single type in a request, which was previously not possible. (GH #1429 #1428) * Add new optimized interface for FE1 format preserving encryption. By caching a number of values computed in the course of the FPE calculation, it provides a 6-7x speedup versus the old API. (GH #1469) * Add DSA and ElGamal keygen functions to FFI (#1426) * Add Pipe::prepend_filter to replace Pipe::prepend (GH #1402) * Fix a memory leak in the OpenSSL block cipher integration, introduced in * 2.2.0 * Use an improved algorithm for generating safe primes which is several tens of times faster. Also, fix a bug in the prime sieving algorithm which caused standard prime generation (like for RSA keys) to be slower than necessary. (GH #1413 #1411) * Correct the return value of PK_Encryptor::maximum_input_size which reported a much too small value (GH #1410) * Remove use of CPU specific optimization flags, instead the user should set these via CXXFLAGS if desired. (GH #1392) * Resolve an issue that would cause a crash in the tests if they were run on a machine without SSE2/NEON/VMX instructions. (GH #1495) * The Python module now tries to load DLLs from a list of names and uses the first one which successfully loads and indicates it supports the desired API level. (GH #1497) * Various minor optimizations for SHA-3 (GH #1433 #1434) * The output of botan --help has been improved (GH #1387) * Add --der-format flag to command line utils, making it possible verify DSA/ECDSA signatures generated by OpenSSL command line (GH #1409) * Add support for --library-suffix option to configure.py (GH #1405 #1404) * Use feature flags to enable/disable system specific code (GH #1378) * Add --msvc-runtime option to allow using static runtime (GH #1499 #210) * Add –enable-sanitizers= option to allow specifying which sanitizers to enable. The existing --with-sanitizers option just enables some default set which is known to work with the minimum required compiler versions. * Use either rst2man or rst2man.py for generating man page as distributions differ on where this program is installed (GH #1516) * The threefish module has been renamed threefish_512 since that is the algorithm it provides. (GH #1477) * The Perl XS based wrapper has been removed, as it was unmaintained and broken. (GH #1412) * The sqlite3 encryption patch under contrib has been removed. It is still maintained by the original author at https://github.com/OlivierJG/botansqlite3- drop explicit package requirements - split binary package and documentation from dynamic library package and make documentation package noarch - merge back Botan2 package to Botan with changelog history - drop Botan patches aarch64-support.patch - doesn't seem to be required anymore Botan-fix_install_paths.patch - doesn't seem to be required no-cpuid-header.patch - SLE11 not target anymore Botan-fix_pkgconfig.patch - this seem to be wrong Botan-no-buildtime.patch - not needed anymore dont-set-mach-value.diff - doesn't apply, unclear and undocumented why it is there Botan-inttypes.patch - not required Botan-ull_constants.patch.bz2 - no reason anymore- change group of libbotan-%{version_suffix} to 'System/Libraries' as requested on review- Don't drop -fstack-clash-protection for openSUSE 42.3 - we just need the Update repository present.- Rename libbotan-devel to libbotan2-devel. We can't have clashing packages in the archive because Botan1 and Botan2 provide the same -devel binary. Botan2 is also no API compatible with Botan.- fix expected version after bump in baselibs.conf too- fix unknown flag -fstack-clash-protection for openSUSE 42.3 - rename to Botan2 - drop Botan2-INT_MAX.patch as not needed anymore - Bump to libbotan 2.4 Changes and new features: * Several build improvements requested by downstream packagers, including the ability to disable building the static library. All makefile constructs that were specific to nmake or GNU make have been eliminated, thus the option ``--makefile-style`` which was previously used to select the makefile type has also been removed. (GH #1230 #1237 #1300 #1318 #1319 #1324 #1325 #1346) * Support for negotiating the DH group as specified in RFC 7919 is now available in TLS (GH #1263) * Support for ARIA-GCM ciphersuites are now available in TLS. They are disabled by default. (GH #1284) * Add support for generating and verifying X.509 objects (certificates, CRLs, etc) using RSA-PSS signatures (GH #1270 and [#1368]) * Add support for AES key wrapping with padding, as specified in RFC 5649 and NIST SP 800-38F (GH #1301) * OCSP requests made during certificate verification had the potential to hang forever. Now the sockets are non-blocking and a timeout is enforced. (GH #1360 fixing GH #1326) * Add ``Public_Key::fingerprint_public`` which allows fingerprinting the public key. The previously available ``Private_Key::fingerprint`` is deprecated, now ``Private_Key::fingerprint_private`` should be used if this is required. (GH #1357) * ECC certificates generated by Botan used an invalid encoding for the parameters field, which was rejected by some certificate validation libraries notably BouncyCastle. (GH #1367) * Loading an ECC key which used OID encoding for the domain parameters, then saving it, would result in a key using the explicit parameters encoding. Now the OID encoding is retained. (GH #1365) * Correct various problems in certificate path validation that arose when multiple paths could be constructed leading to a trusted root but due to other constraints only some of them validated. (GH [#1363]) * It is now possible for certificate validation to return warning indicators, such as that the distinguished name is not within allowed limits or that a certificate with a negative serial number was observed. (GH #1363 #1359) * XMSS signatures now are multi-threaded for improved performance (GH #1267) * Fix a bug that caused the TLS peer cert list to be empty on a resumed session. (GH #1303 #1342) * Increase the maximum HMAC key length from 512 bytes to 4096 bytes. This allows using a DH key exchange in TLS with a group greater than 4096 bits. (GH #1316) * Fix a bug in the TLS server where, on receiving an SSLv3 client hello, it would attempt to negotiate TLS v1.2. Now a protocol_version alert is sent. Found with tlsfuzzer. (GH #1316) * Fix several bugs related to sending the wrong TLS alert type in various error scenarios, caught with tlsfuzzer. * Add support for a ``tls_http_server`` command line utility which responds to simple GET requests. This is useful for testing against a browser, or various TLS test tools which expect the underlying protocol to be HTTP. (GH #1315) * Add an interface for generic PSK data stores, as well as an implementation which encrypts stored values with AES key wrapping. (GH #1302) * Optimize GCM mode on systems both with and without carryless multiply support. This includes a new base case implementation (still constant time), a new SSSE3 implementation for systems with SSSE3 but not clmul, and better algorithms for systems with clmul and pmull. (GH #1253 #1263) * Various optimizations for OCB, CFB, CTR, SM3, SM4, GMAC, BLAKE2b, Blowfish, Twofish, CAST-128, and CRC24 (GH #1281) * Salsa20 now supports the seek operation. * Add ``EC_Group::known_named_groups`` (GH #1339) * Symmetric algorithms (block ciphers, stream ciphers, MACs) now verify that a key was set before accepting data. Previously attempting to use an unkeyed object would instead result in either a crash or invalid outputs. (GH #1279) * The X509 certificate, CRL and PKCS10 types have been heavily refactored internally. Previously all data of these types was serialized to strings, then in the event a more complicated data structure (such as X509_DN) was needed, it would be recreated from the string representation. However the round trip process was not perfect and could cause fields to become lost. This approach is no longer used, fixing several bugs (GH #1010 #1089 #1242 #1252). The internal data is now stored in a ``shared_ptr``, so copying such objects is now very cheap. (GH #884) * ASN.1 string objects previously held their contents as ISO 8859-1 codepoints. However this led to certificates which contained strings outside of this character set (eg in Cyrillic, Greek, or Chinese) being rejected. Now the strings are always converted to UTF-8, which allows representing any character. In addition, UCS-4 strings are now supported. (GH #1113 #1250 #1287 #1289) * It is now possible to create an uninitialized X509_Certificate object. Such an object will throw if any attempt to access its members is made. (GH #1335) * In BER decoder, avoid unbounded stack recursion when parsing nested indefinite length values. Now at most 16 nested indefinite length values are accepted, anything deeper resulting in a decoding error. (GH #1304 OSS-Fuzz 4353). * A new ASN.1 printer API allows generating a string representation of arbitrary BER data. This is used in the ``asn1print`` command line utility and may be useful in other applications, for instance for debugging. * New functions for bit rotations that distinguish rotating by a compile-time constant vs a runtime variable rotation. This allows better optimizations in both cases. Notably performance of CAST-128 and CAST-256 are substantially improved. (GH #1247) * TLS CBC ciphersuites now are implemented using the standard CBC code, instead of reimplementing CBC inside the TLS stack. This allows for parallel decryption of TLS CBC ciphertexts, and improves performance especially when using AES hardware support. (GH #1269) * Add callbacks to make it possible for an application using TLS to provide custom implementations of signature schemes, eg when offloading the computations to another device. (GH #1332) * Use a direct calculation for calendar computations instead of relying on non-portable operating system interfaces. (GH #1336) * Fix a bug in the amalgamation generation which could cause build failures on some systems including macOS. (GH #1264 #1265) * A particular code sequence in TLS handshake would always (with an ECC ciphersuite) result in an exception being thrown and then caught. This has changed so no exception is thrown. (GH #1275) * The code for byteswapping has been improved for ARMv7 and for Windows x86-64 systems using MSVC. (GH #1274) * The GMAC class no longer derives from GHASH. This should not cause any noticeable change for applications. (GH #1253) * The base implementation of AES now uses a single 4K table, instead of 4 such tables. This offers a significant improvement against cache-based side channels without hurting performance too much. In addition the table is now guaranteed to be aligned on a cache line, which ensures the additional countermeasure of reading each cache line works as expected. (GH #1255) * In TLS client resumption, avoid sending a OCSP stapling request. This caused resumption failures with some servers. (GH [#1276]) * The overhead of making a call through the FFI layer has been reduced. * The IDs for SHA-3 PKCSv1.5 signatures added in 2.3.0 were incorrect. They have been changed to use the correct encoding, and a test added to ensure such errors do not recur. * Counter mode allows setting a configurable width of the counter. Previously it was allowed for a counter of even 8 bits wide, which would mean the keystream would repeat after just 256 blocks. Now it requires the width be at least 32 bits. The only way this feature could be used was by manually constructing a ``CTR_BE`` object and setting the second parameter to something in the range of 1 to 3. * A new mechanism for formatting ASN.1 data is included in ``asn1_print.h``. This is the same functionality used by the command line ``asn1print`` util, now cleaned up and moved to the library. * Add ``Pipe::append_filter``. This is like the existing (deprecated) ``Pipe::append``, the difference being that ``append_filter`` only allows modification before the first call to ``start_msg``. (GH #1306 #1307) * The size of ASN1_Tag is increased to 32 bits. This avoids a problem with UbSan (GH #751) * Fix a bug affecting bzip2 compression. In certain circumstances, compression would fail with ``BZ_SEQUENCE_ERROR`` due to calling bzlib in an way it does not support. (GH #1308 #1309) * In 2.3.0, final annotations were added to many classes including the TLS policies (like ``Strict_Policy`` and ``BSI_TR_02102_2``). However it is reasonable and useful for an application to derive from one of these policies, so as to create an application specific policy that is based on a library-provided policy, but with a few tweaks. So the final annotations have been removed on these classes. (GH #1292) * A new option ``--with-pdf`` enables building a PDF copy of the handbook. (GH #1337) * A new option ``--with-rst2man`` enables building a man page for the command line util using Docutils rst2man. (GH #1349) * Support for NEON is now enabled under Clang. * Now the compiler version is detected using the preprocessor, instead of trying to parse the output of the compiler's version string, which was subject to problems with localization. (GH [#1358]) * By default the gzip compressor will not include a timestamp in the header. The timestamp can be set by passing it to the ``Gzip_Compression`` constructor. * Add an OID for RIPEMD-160 * Fixes for CMake build (GH #1251) * Avoid some signed overflow warnings (GH #1220 #1245) * As upstream support for Native Client has been deprecated by Google, support is now also deprecated in Botan and will be removed in a future release. * The Perl-XS wrapper has not been maintained in many years. It is now deprecated, and if no attempts are made to revive it, it will be removed in a future release. * Support for building on IRIX has been removed.- add Botan2-INT_MAX.patch * Fix “INT_MAX was not declared in this scope” in openSUSE Leap 42.1- fix build. python3 configure itself is useless， we should make package python3 too.- configure Botan explicitly with python3- Update to 1.10.17 - Address a side channel affecting modular exponentiation. An attacker capable of a local or cross-VM cache analysis attack may be able to recover bits of secret exponents as used in RSA, DH, etc. CVE-2017-14737 Workaround a miscompilation bug in GCC 7 on x86-32 affecting GOST-34.11 hash function. (GH #1192 #1148 #882, bsc#1060433) - Add SecureVector::data() function which returns the start of the buffer. This makes it slightly simpler to support both 1.10 and 2.x APIs in the same codebase. When compiled by a C++11 (or later) compiler, a template typedef of SecureVector, secure_vector, is added. In 2.x this class is a std::vector with a custom allocator, so has a somewhat different interface than SecureVector in 1.10. But this makes it slightly simpler to support both 1.10 and 2.x APIs in the same codebase. - Fix a bug that prevented configure.py from running under Python3 - Botan 1.10.x does not support the OpenSSL 1.1 API. Now the build will [#]error if OpenSSL 1.1 is detected. Avoid –with-openssl if compiling against 1.1 or later. (GH #753) - Import patches from Debian adding basic support for building on aarch64, ppc64le, or1k, and mipsn32 platforms. * obsoletes CVE-2017-14737.patch * refreshes aarch64-support.patch * drop ppc64le-support.patch for upstream version (disables altivec support as per concerns by upstream)- Fix for CVE-2017-14737: A cryptographic cache-based side channel in the RSA implementation allows local attacker to recover information about RSA secret keys. * add CVE-2017-14737.patch- Explicitly require libopenssl-1_0_0-devel (bsc#1055322) * Botan 1.x won't support OpenSSL 1.1 (https://github.com/randombit/botan/issues/753)- Add patch to build SLES11 (allows for simplified backporting, e.g. bsc#968030) * add no-cpuid-header.patch - Clean up spec file- Update to 1.10.16 (Fixes CVE-2017-2801, bsc#1033605) * Fix a bug in X509 DN string comparisons that could result in out of bound reads. This could result in information leakage, denial of service, or potentially incorrect certificate validation results. (CVE-2017-2801) * Avoid use of C++11 std::to_string in some code added in 1.10.14 (GH #747 #834) - Changes from 1.10.15: * Change an unintended behavior of 2.0.0, which named the include directory botan-2.0. Since future release of Botan-2 should be compatible with code written against old versions, there does not seem to be any reason to * version the include directory with the minor number. (GH #830 #833) * Fix a bug which caused an error when building on Cygwin or other platforms where shared libraries are not supported. (GH #821) * Enable use of readdir on Cygwin, which allows the tests to run (GH #824) * Switch to readthedocs Sphinx theme by default (GH #822 #823)- Update to 1.10.14 * Fix integer overflow during BER decoding, found by Falko Strenzke. This bug is not thought to be directly exploitable but upgrading ASAP is advised. (CVE-2016-9132) * Fix two cases where (in error situations) an exception would be thrown from a destructor, causing a call to std::terminate. * When RC4 is disabled in the build, also prevent it from being included in the OpenSSL provider. (GH #638)- Update to 1.10.13 * Use constant time modular inverse algorithm to avoid possible side channel attack against ECDSA (CVE-2016-2849) * Use constant time PKCS #1 unpadding to avoid possible side channel attack against RSA decryption (CVE-2015-7827) * Avoid a compilation problem in OpenSSL engine when ECDSA was disabled. Gentoo bug 542010- Remove Qt5 dependency, since nothing is using it anymore. - Fix double-prefix in botan-config and pkgconfig file.- Update to 1.10.12 - Version 1.10.12, 2016-02-03 * In 1.10.11, the check in PointGFp intended to check the affine y argument actually checked the affine x again. Reported by Remi Gacogne * The CVE-2016-2195 overflow is not exploitable in 1.10.11 due to an additional check in the multiplication function itself which was also added in that release, so there are no security implications from the missed check. However to avoid confusion the change was pushed in a new release immediately. * The 1.10.11 release notes incorrectly identified CVE-2016-2195 as CVE-2016-2915 - Version 1.10.11, 2016-02-01 * Resolve heap overflow in ECC point decoding. CVE-2016-2195 Resolve infinite loop in modular square root algorithm. CVE-2016-2194 Correct BigInt::to_u32bit to not fail on integers of exactly 32 bits. GH #239- Add gpg signature - Cleanup spec file with spec-cleaner- Fix Source0 URL- bump SONAME to libbotan-1_10-1 - Update to 1.10.10 * SECURITY: The BER decoder would crash due to reading from offset 0 of an empty vector if it encountered a BIT STRING which did not contain any data at all. As the type requires a 1 byte field this is not valid BER but could occur in malformed data. Found with afl. CVE-2015-5726 * SECURITY: The BER decoder would allocate a fairly arbitrary amount of memory in a length field, even if there was no chance the read request would succeed. This might cause the process to run out of memory or invoke the OOM killer. Found with afl. CVE-2015-5727 * Due to an ABI incompatible (though not API incompatible) change in this release, the version number of the shared object has been increased. * The default TLS policy no longer allows RC4. * Fix a signed integer overflow in Blue Midnight Wish that may cause incorrect computations or undefined behavior. - Update to 1.10.9 * Fixed EAX tag verification to run in constant time * The default TLS policy now disables SSLv3. * A crash could occur when reading from a blocking random device if the device initially indicated that entropy was available but a concurrent process drained the entropy pool before the read was initiated. * Fix decoding indefinite length BER constructs that contain a context sensitive tag of zero. Github pull 26 from Janusz Chorko. * The botan-config script previously tried to guess its prefix from the location of the binary. However this was error prone, and now the script assumes the final installation prefix matches the value set during the build.
