Upstream changes:
Version 2.17.3, 2020-12-21
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
* Change base64, base58, base32, and hex encoding and decoding opearations
to run in constant time (GH #2549)
* Fix a build problem on PPC64 building with Clang (GH #2547)
* Fix an install problem introduced in 2.17.2 affecting MSVC 2015
* Fix use of -L flag in linking when configured using ``--with-external-libdir``
(GH #2496)
* Fix a build problem on big-endian PowerPC related to VSX instructions
in the AES code. (GH #2515)
Version 2.17.2, 2020-11-13
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
* Fix an build problem on ppc64 introduced with certain recent
versions of GCC or binutils where using the DARN instruction
requires using an appropriate -mcpu flag to enable the instruction
in the assembler. (GH #2481 2463)
* Resolve an issue in the modular square root algorithm where a loop
to find a quadratic non-residue could, for a carefully chosen
composite modulus, not terminte in a timely manner. (GH #2482#2476)
* Fix a regression in MinGW builds introduced in 2.17.1
Version 2.17.1, 2020-11-07
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
* Fix a build problem that could occur if Python was not in the PATH.
This was known to occur on some installations of macOS.
* Re-enable support for the x86 CLMUL instruction on Visual C++, which was
accidentally disabled starting in 2.12.0. (GH #2460)
Version 2.17.0, 2020-11-05
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
* Fix a bug in ECDSA which could occur when the group size and hash length
differ. In this case, on occasion the generated signature would not be
accepted by other ECDSA implementations. This was particularly likely to
affect users of 160-bit or 239-bit curves. (GH #2433#2415)
* Fix a bug in ECDSA verification when the public key was chosen to be
a small multiple of the group generator. In that case, verification
would fail even if the signature was actually valid. (GH #2425)
* SIV's functionality of supporting multiple associated data inputs has been
generalized onto the AEAD_Mode interface. However at the moment SIV is the
only AEAD implemented which supports more than one AD. (GH #2440)
* The contents of ASN.1 headers ``asn1_str.h``, ``asn1_time.h``, ``asn1_oid.h``
and ``alg_id.h`` have been moved to ``asn1_obj.h``. The header files remain
but simply forward the include to ``asn1_obj.h``. These now-empty header files
are deprecated, and will be removed in a future major release. (GH #2441)
* The contents of X.509/PKIX headers ``asn1_attribute.h`` ``asn1_alt_name.h``
``name_constraint.h`` ``x509_dn.h`` ``cert_status.h`` and ``key_constraint.h``
have been merged into ``pkix_enums.h`` (for enumerations) and ``pkix_types.h``
(for all other definitions). The previous header files remain but simply
forward the include to the new header containing the definition. These
now-empty header files are deprecated, and will be removed in a future major
release. (GH #2441)
* A number of other headers including those related to HOTP/TOTP, XMSS,
PKCS11, PSK_DB have also been merged. Any now deprecated/empty headers
simply include the new header and issue a deprecation warning.
(GH #2443#2446#2447 2448 #2449)
* Small optimizations in the non-hardware assisted AES key generation
code path (GH #2417#2418)
* Move the GHASH code to a new module in utils, making it possible
to build GMAC support without requiring GCM (GH #2416)
* Add more detection logic for AVX-512 features (GH #2430)
* Avoid std::is_pod which is deprecated in C++20 (GH #2429)
* Fix a bug parsing deeply nested cipher names (GH #2426)
* Add support for ``aarch64_be`` target CPU (GH #2422)
* Fix order of linker flags so they are always applied effectively (GH #2420)
* Prevent requesting DER encoding of signatures when the algorithm
did not support it (GH #2419)
Version 2.16.0, 2020-10-06
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
* 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. (GH #2399)
* 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. (GH #2409)
* RandomNumberGenerator::add_entropy_T assumed its input was a POD
type but did not verify this. (GH #2403)
* Support OCSP responders that live on a non-standard port (GH #2401)
* Add support for Solaris sandbox (GH #2385)
* Support suffixes on release numbers for alpha/beta releases (GH #2404)
* 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. (GH #2392#2390)
* 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. (GH #2392#2388)
Version 2.15.0, 2020-07-07
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
* 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.
Version 2.14.0, 2020-04-06
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
* 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. Thanks to Maximilian Blochberger for reporting this.
(GH #2312)
* 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)
* Use the library thread pool instead of a new thread for RSA computations,
improving signature performance by up to 20%. (GH #2257)
* Precompute and cache additional fields in ``X509_Certificate`` (GH #2250)
* Add a CLI utility ``cpu_clock`` which estimates the speed of the
processor cycle counter. (GH #2251)
* Fix a bug which prevented using DER-encoded ECDSA signatures with a PKCS11
key (GH #2293)
* Enable use of raw block ciphers from CommonCrypto (GH #2278)
* Support for splitting up the amalgamation file by ABI extension has
been removed. Instead only ``botan_all.cpp`` and ``botan_all.h`` are
generated. (GH #2246)
* Improve support for baremetal systems with no underlying OS, with
target OS ``none`` (GH #2303#2304#2305)
* The build system now avoids using ``-rpath=$ORIGIN`` or (on macOS)
install_name which allowed running the tests from the build
directory without setting ``LD_LIBRARY_PATH``/``DYLD_LIBRARY_PATH``
environment variables. Instead set the dynamic linker variables
appropriately, or use ``make check``. (GH #2294#2302)
* Add new option ``--name-amalgamation`` which allows naming the
amalgamation output, instead of the default ``botan_all``. (GH #2246)
* Avoid using symbolic links on Windows (GH #2288#2286#2285)
* Fix a bug that prevented compilation of the amalgamation on ARM and
POWER processors (GH #2245#2241)
* Fix some build problems under Intel C++ (GH #2260)
* Remove use of Toolhelp Windows library, which was known to trigger
false positives under some antivirus systems. (GH #2261)
* Fix a compilation problem when building on Windows in Unicode mode.
Add Unicode build to CI to prevent regressions. (GH #2254#2256)
* Work around a GCC bug affecting old libc (GH #2235)
* Workaround a bug in macOS 10.15 which caused a test to crash.
(GH #2279#2268)
* Avoid a crash in PKCS8::load_key due to a bug in Clang 8.
(GH #2277)
Version 2.13.0, 2020-01-06
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
* 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)
* It is now possible to disable TLS v1.0/v1.1 and DTLS v1.0 at build time.
(GH #2188)
* The format of encrypted TLS sessions has changed, which will
invalidate all existing session tickets. The new format will make
it easier to support ticket key rotation in the future. (GH #2225)
* Improve RSA key generation performance (GH #2148)
* Make gcd computation constant-time (GH #2147)
* Add AVX2 implementation of SHACAL2 (GH #2196)
* Update BSI policy to reflect 2019 update of TR 02102-2 (GH #2195)
* 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)
* Disable stack protector on MinGW as it causes crashes with some recent
versions. (GH #2187)
* On Windows the DLL is now installed into the binary directory (GH #2233)
* Previously Windows required an explicit ``.lib`` suffix be added when
providing an explicit library name, as is used for example for Boost.
Now the ``.lib`` suffix is implicit, and should be omitted.
* Remove the 32-bit x86 inline asm for Visual C++ as it seemed to not offer
much in the way of improved performance. (GH #2204#256)
* Resolve all compile time warnings generated by GCC, Clang and MSVC.
Modify CI to compile with warnings-as-errors. (GH #2170#2206#2211#2212)
* Fix bugs linking to 3rd party libraries on Windows due to invalid
link specifiers. (GH #2210#2215)
* Add long input and NIST Monte-Carlo hash function tests.
* Fix a bug introduced in 2.12.0 where ``TLS::Channel::is_active`` and
``TLS::Channel::is_closed`` could simultaneously return true.
(GH #2174#2171)
* Use ``std::shared_ptr`` instead of ``boost::shared_ptr`` in some examples.
(GH #2155)
Version 2.12.1, 2019-10-14
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
* Fix a bug that prevented building with nmake (GH #2142#2141)
* Fix an issue where make install would attempt to build targets which
were disabled. (GH #2140)
* If the option ``--without-documentation`` is used, avoid invoking the
documentation build script. (GH #2138)

* Fix a bug in CCM encryption, where it was possible to call ``finish`` without
ever setting a nonce (GH #2151#2150)
* Improve ECIES/DLIES interfaces. If no initialization vector was set, they
would typically produce hard to understand exceptions. (GH #2151#2150)
Version 2.12.0, 2019-10-07
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
* 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.
(GH #2061)
* 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)

* 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)

* Support Argon2 outputs longer than 64 bytes (GH #2079#2078)
* Correct a bug in CAST-128 which caused incorrect computation using
11, 13, 14, or 15 byte keys. (GH #2081)
* Fix a bug which would cause Streebog to produce incorrect outputs for
certain messages (GH #2082#2083)

it was requested to use an iteration count of 0. (GH #2090#2088)
* The BearSSL provider has been removed (GH #2020)
* Add a new ``entropy`` cli which allows sampling the output of
the entropy sources.
* Add new ``base32_enc`` and ``base32_dec`` cli for base32 encoding
operations. (GH #2111)
* Support setting TLS policies in CLIs like ``tls_client`` and
``tls_proxy_server`` (GH #2047)
* The tests now run in multithreaded mode by default. Provide option
``--test-threads=1`` to return to previous single-threaded
behavior. (GH #2071#2075)
* Cleanups in TLS record layer (GH #2021)
* Fix typos in some OCSP enums which used "OSCP" instead. (GH #2048)
* In the Python module, avoid trying to load DLLs for names that
don't match the current platform (GH #2062#2059)
* In the Python module, also look for ``botan.dll`` so Python
wrapper can run on Windows. (GH #2059#2060)

#2016#2033#513)
* Add Android NDK build to Travis CI (GH #2017)
Some of the more important changes:
- Fix incorrect truncation in Bcrypt. Passwords in length between 56 and
72 characters were truncated at 56 characters. Found and reported by
Solar Designer. (CVE-2017-7252) (GH #938)
- 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.
Found independently by Cisco Talos team and OSS-Fuzz. (CVE-2017-2801)
- Correct minimum work factor for Bcrypt password hashes. All other
implementations require the work factor be at least 4. Previously
Botan simply required it be greater than zero. (GH #938)
- Converge on a single side channel silent EC blinded multiply
algorithm. Uses Montgomery ladder with order/2 bits scalar blinding
and point randomization now by default. (GH #893)
- Add ability to search for certificates using the SHA-256 of the
distinguished name. (GH #900)
- Support a 0-length IV in ChaCha stream cipher. Such an IV is treated
identically to an 8-byte IV of all zeros.
- Previously Botan forbid any use of times past 2037 to avoid Y2038
issues. Now this restriction is only in place on systems which have a
32-bit time_t. (GH #933 fixing #917)
- Fix a longstanding bug in modular exponentiation which caused most
exponentiations modulo an even number to have an incorrect result;
such moduli occur only rarely in cryptographic contexts. (GH #754)
- Fix a bug in BigInt multiply operation, introduced in 1.11.30, which
could cause incorrect results. Found by OSS-Fuzz fuzzing the ressol
function, where the bug manifested as an incorrect modular
exponentiation. OSS-Fuzz bug #287
- Fix a bug that meant the “ietf/modp/6144” and “ietf/modp/8192”
discrete log groups used an incorrect value for the generator,
specifically the value (p-1)/2 was used instead of the correct value
of 2.
- DL_Group strong generation previously set the generator to 2. However
sometimes 2 generates the entire group mod p, rather than the subgroup
mod q. This is invalid by X9.42 standard, and exposes incautious
applications to small subgroup attacks. Now DL_Group uses the smallest
g which is a quadratic residue. (GH #818)
- The default TLS policy now requires 2048 or larger DH groups by
default.
- The default Path_Validation_Restrictions constructor has changed to
require at least 110 bit signature strength. This means 1024 bit RSA
certificates and also SHA-1 certificates are rejected by default. Both
settings were already the default for certificate validation in TLS
handshake, but this changes it for applications also.
- 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)
- Add post-quantum signature scheme XMSS. Provides either 128 or 256 bit
(post-quantum) security, with small public and private keys, fast
verification, and reasonably small signatures (2500 bytes for 128-bit
security). Signature generation is very slow, on the order of seconds.
And very importantly the signature scheme is stateful: each leaf index
must only be used once, or all security is lost. In the appropriate
system where signatures are rarely generated (such as code signing)
XMSS makes an excellent choice. (GH #717#736)
- Add support for client-side OCSP stapling to TLS. (GH #738)
- Previously both public and private keys performed automatic self
testing after generation or loading. However this often caused
unexpected application performance problems, and so has been removed.
Instead applications must call check_key explicitly. (GH #704)
- Fix TLS session resumption bugs which caused resumption failures if an
application used a single session cache for both TLS and DTLS. (GH
#688)
- The default TLS policy now disables static RSA ciphersuites, all DSA
ciphersuites, and the AES CCM-8 ciphersuites. Disabling static RSA by
default protects servers from oracle attacks, as well as enforcing a
forward secure ciphersuite. Some applications may be forced to
re-enable RSA for interop reasons. DSA and CCM-8 are rarely used, and
likely should not be negotiated outside of special circumstances.
- The default TLS policy now prefers ChaCha20Poly1305 cipher over any
AES mode.
- The default TLS policy now orders ECC curve preferences in order by
performance, with x25519 first, then P-256, then P-521, then the rest.
- avoid side channel with OAEP (CVE-2016-8871)
- avoid Lucky13 timing attack against CBC-based TLS cipher
- added X25519-based key exchange for TLS
- add support for the TLS Supported Point Formats Extension from
RFC 4492
- add support for the NewHope Ring-LWE key encapsulation algorithm
for estimated ~200 bit security level against a quantum attacker.
- add support for TLS Encrypt-then-MAC extension
- Fix undefined behavior in Curve25519 for 32bit platforms
- bugfix for GCM when 32-bit counters overflowed
- added ChaCha20Poly1305 TLS cipher
- CVE-2016-2849: side channel attack against DSA and ECDSA
- CVE-2016-2850: failure to enforce TLS policies could lead to weaker
algorithms being choosen
- CVE-2016-2195: heap overflow in ECC point decoding
- CVE-2016-2196: heap overflow in P-521 reduction
- CVE-2016-2194: DOS against the modular reduction
- CVE-2015-7824: padding oracle attack against TLS CBC
- CVE-2015-7825: DOS due to certificate chains
- CVE-2015-7826: wildcard certifications verification failures
- CVE-2015-7827: protection against PKCS#1 side channel issues
- CVE-2015-5726: potential DOS with invalid zero-length BER
- CVE-2015-5727: unbound memory use with BER
- deprecation or removal of various insecure crypto primitives
- TLS heartbeat removed
- various other bugfixes and improvements.
