LibreSSL 2.5.1

+LibreSSL 2.5.3
+
+
+ - libtls now supports ALPN and SNI
+
+
- libtls adds a new callback interface for integrating custom IO
+ functions. Thanks to Tobias Pape.
+
+
- libtls now handles 4 cipher suite groups:
+
+ - "secure" (TLSv1.2+AEAD+PFS)
+
- "compat" (HIGH:!aNULL)
+
- "legacy" (HIGH:MEDIUM:!aNULL)
+
- "insecure" (ALL:!aNULL:!eNULL)
+
+ This allows for flexibility and finer grained control, rather than
+ having two extremes (an issue raised by Marko Kreen some time ago).
+
+ - Tightened error handling for tls_config_set_ciphers().
+
+
- libtls now always loads CA, key and certificate files at the time the
+ configuration function is called. This simplifies code and results in
+ a single memory based code path being used to provide data to libssl.
+
+
- Add support for OCSP intermediate certificates.
+
+
- Added functions used by stunnel and exim from BoringSSL - this
+ brings in X509_check_host, X509_check_email, X509_check_ip, and
+ X509_check_ip_asc.
+
+
- Added initial support for iOS, thanks to Jacob Berkman.
+
+
- Improved behavior of arc4random on Windows when using memory leak
+ analysis software.
+
+
- Correctly handle an EOF that occurs prior to the TLS handshake
+ completing. Reported by Vasily Kolobkov, based on a diff from Marko
+ Kreen.
+
+
- Limit the support of the "backward compatible" ssl2 handshake to
+ only be used if TLS 1.0 is enabled.
+
+
- Fix incorrect results in certain cases on 64-bit systems when
+ BN_mod_word() can return incorrect results. BN_mod_word() now can
+ return an error condition. Thanks to Brian Smith.
+
+
- Added constant-time updates to address CVE-2016-0702
+
+
- Fixed undefined behavior in BN_GF2m_mod_arr()
+
+
- Removed unused Cryptographic Message Support (CMS)
+
+
- More conversions of long long idioms to time_t
+
+
- Improved compatibility by avoiding printing NULL strings with
+ printf.
+
+
- Reverted change that cleans up the EVP cipher context in
+ EVP_EncryptFinal() and EVP_DecryptFinal(). Some software relies on the
+ previous behaviour.
+
+
- Avoid unbounded memory growth in libssl, which can be triggered
+ by a TLS client repeatedly renegotiating and sending OCSP Status
+ Request TLS extensions.
+
+
- Avoid falling back to a weak digest for (EC)DH when using SNI
+ with libssl.
+
+
- X509_cmp_time() now passes a malformed GeneralizedTime field as
+ an error. Reported by Theofilos Petsios.
+
+
- Detect zero-length encrypted session data early, instead of when
+ malloc(0) fails or the HMAC check fails. Noted independently by
+ jsing@ and Kurt Cancemi.
+
+
- Check for and handle failure of HMAC_{Update,Final} or
+ EVP_DecryptUpdate().
+
+
- Massive update and normalization of manpages, conversion to
+ mandoc format. Many pages were rewritten for clarity and accuracy.
+ Portable doc links are up-to-date with a new conversion tool.
+
+
- Curve25519 Key Exchange support.
+
+
- Support for alternate chains for certificate verification.
+
+
- Code cleanups, CBB conversions, further unification of DTLS/SSL
+ handshake code, further ASN1 macro expansion and removal.
+
+
- Private symbol are now hidden in libssl and libcryto.
+
+
- Friendly certificate verification error messages in libtls, peer
+ verification is now always enabled.
+
+
- Added OCSP stapling support to libtls and netcat.
+
+
- Added ocspcheck utility to validate a certificate against its OCSP
+ responder and save the reply for stapling
+
+
- Enhanced regression tests and error handling for libtls.
+
+
- Added explicit constant and non-constant time BN functions,
+ defaulting to constant time wherever possible.
+
+
- Moved many leaked implementation details in public structs behind
+ opaque pointers.
+
+
- Added ticket support to libtls.
+
+
- Added support for setting the supported EC curves via
+ SSL{_CTX}_set1_groups{_list}() - also provide defines for the
+ previous SSL{_CTX}_set1_curves{_list} names. This also changes
+ the default list of curves to be X25519, P-256 and P-384. All
+ other curves must be manually enabled.
+
+
- Added -groups option to openssl(1) s_client for specifying the
+ curves to be used in a colon-separated list.
+
+
- Merged client/server version negotiation code paths into one,
+ reducing much duplicate code.
+
+
- Removed error function codes from libssl and libcrypto.
+
+
- Fixed an issue where a truncated packet could crash via an OOB
+ read.
+
+
- Added SSL_OP_NO_CLIENT_RENEGOTIATION option that disallows
+ client-initiated renegotiation. This is the default for libtls
+ servers.
+
+
- Avoid a side-channel cache-timing attack that can leak the ECDSA
+ private keys when signing. This is due to BN_mod_inverse() being
+ used without the constant time flag being set. Reported by Cesar
+ Pereida Garcia and Billy Brumley (Tampere University of
+ Technology). The fix was developed by Cesar Pereida Garcia.
+
+
- iOS and MacOS compatibility updates from Simone Basso and Jacob
+ Berkman.
+
+
- Added the recallocarray(3) memory allocation function, and
+ converted various places in the library to use it, such as CBB
+ and BUF_MEM_grow. recallocarray(3) is similar to
+ reallocarray. Newly allocated memory is cleared similar to
+ calloc(3). Memory that becomes unallocated while shrinking or
+ moving existing allocations is explicitly discarded by unmapping
+ or clearing to 0.
+
+
- Added new root CAs from SECOM Trust Systems / Security
+ Communication of Japan.
+
+
- Added EVP interface for MD5+SHA1 hashes.
+
+
- Fixed DTLS client failures when the server sends a certificate
+ request.
+
+
- Correct handling of padding when upgrading an SSLv2 challenge
+ into an SSLv3/TLS connection.
+
+
- Allow protocols and ciphers to be set on a TLS config object in
+ libtls.
+
+
- Improved nc(1) TLS handshake CPU usage and server-side error
+ reporting.
