This also includes the openssl-devel package. This is an upstream security and bugfix release. The Cygwin release is the vanilla version, no additional patches. The previous version, 0.9.8f, has been release a week ago, 11-Oct-2007. It was a security and bugfix release, but for some reason no official announcement has been sent, only a list of vulnerabilities fixed in 0.9.8f. The official announcement for 0.9.8g does not contain any hint about the security fixes applied to the 0.9.8f version. For that reason you will find below the official release message for 0.9.8g, as well as the list of vulnerabilities fixed in 0.9.8f. OpenSSL Security Advisory [12-Oct-2007] ======================================================================= OpenSSL Vulnerabilities ----------------------- Vulnerability A --------------- Andy Polyakov discovered a flaw in OpenSSL's DTLS implementation which could lead to the compromise of clients and servers with DTLS enabled. DTLS is a datagram variant of TLS specified in RFC 4347 first supported in OpenSSL version 0.9.8. Note that the vulnerabilities do not affect SSL and TLS so only clients and servers explicitly using DTLS are affected. We believe this flaw will permit remote code execution. This vulnerability is tracked as CVE-2007-4995. Versions Affected ----------------- All releases of 0.9.8 prior to 0.9.8f. Recommendation -------------- Either a) Upgrade to the latest version of OpenSSL (0.9.8f) and rebuild all packages using OpenSSL for DTLS. or, b) Disable DTLS. Vulnerability B --------------- Moritz Jodeit found an off-by-one error in SSL_get_shared_ciphers(), a function that should normally only be used for logging or debugging. The impact of this overflow is unclear. This vulnerability is tracked as CVE-2007-5135. Versions Affected ----------------- All releases of 0.9.8 prior to 0.9.8f. All releases of 0.9.7 prior to 0.9.7m. (Note that versions prior to 0.9.8d and 0.9.7l actually had a worse problem in the same function). Recommendation -------------- a) Don't use SSL_get_shared_ciphers(). OR b) Upgrade to 0.9.8f. ======================================================================= Official release message: ======================================================================= OpenSSL - The Open Source toolkit for SSL/TLS http://www.openssl.org/ The OpenSSL project team is pleased to announce the release of version 0.9.8g of our open source toolkit for SSL/TLS.
