A vulnerability has been found and corrected in GnuTLS :

Buffer overflow in the gnutls_session_get_data function in lib/gnutls_session.c in GnuTLS 2.12.x before 2.12.14 and 3.x before 3.0.7, when used on a client that performs nonstandard session resumption, allows remote TLS servers to cause a denial of service (application crash) via a large SessionTicket (CVE-2011-4128).

The updated packages have been patched to correct this issue.
