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.

Status:

Need to determine if this patch has been sent upstream.
