CVE-2012-2686
First published: Tue Feb 05 2013(Updated: )
A flaw in the OpenSSL handling of CBC ciphersuites in TLS 1.1 and TLS 1.2 on AES-NI (Advanced Encryption Standard New Instructions) supporting platforms [1] can be exploited in a DoS attack. Anyone using an AES-NI platform for TLS 1.2 or TLS 1.1 on OpenSSL 1.0.1c is affected. Platforms which do not support AES-NI or versions of OpenSSL which do not implement TLS 1.2 or 1.1 (for example OpenSSL 0.9.8 and 1.0.0) are not affected.
