SynopsisThe remote Debian host is missing a security-related update.
DescriptionIt 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.)
SolutionUpgrade the openssl packages.
For the stable distribution (squeeze), this problem has been fixed in version 0.9.8o-4squeeze13.
