A NULL pointer dereference flaw was discovered in GnuTLS's
gnutls_x509_dn_oid_name(). The function, when called with the
GNUTLS_X509_DN_OID_RETURN_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).");
