We have released LibreSSL 2.5.0, which will be arriving in the LibreSSL directory of your local OpenBSD mirror soon. It includes the following changes: * 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. The LibreSSL project continues improvement of the codebase to reflect modern, safe programming practices. We welcome feedback and improvements from the broader community. Thanks to all of the contributors who helped make this release possible.
