Debian DSA-2475-1 : openssl - integer underflow

It was discovered that openssl did not correctly handle explicit Initialization Vectors for CBC encryption modes, as used in TLS 1.1, 1.2, and DTLS. An incorrect calculation would lead to an integer underflow and incorrect memory access, causing denial of service application crash. %NASLMINLEVEL...
