Updated gnutls packages fix security vulnerabilities:
A NULL pointer dereference flaw was discovered in GnuTLS's gnutlsx509dnoidname(). The function, when called with the GNUTLSX509DNOIDRETURN_OID flag, should not return NULL to its caller. However, it could previously return NULL when parsed X.509 certificates included specific OIDs (CVE-2014-3465).
A flaw was found in the way GnuTLS parsed session ids from Server Hello packets of the TLS/SSL handshake. A malicious server could use this flaw to send an excessively long session id value and trigger a buffer overflow in a connecting TLS/SSL client using GnuTLS, causing it to crash or, possibly, execute arbitrary code (CVE-2014-3466).
