This update for GnuTLS provides the following fixes :

  • Fix typo in patch for gnutls-cli that can cause a crash.
    (bnc#659907)

  • Fix Buffer overflow in the gnutls_session_get_data function in lib/gnutls_session.c , 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)
