Ubuntu Security Notice USN-251-1 - Evgeny Legerov discovered a buffer overflow in the DER format decoding function of the libtasn library. This library is mainly used by the GNU TLS library; by sending a specially crafted X.509 certificate to a server which uses TLS encryption/authentication, a remote attacker could exploit this to crash that server process and possibly even execute arbitrary code with the privileges of that server.
