Updated gnutls packages fix CVE-2104-3465-6Publication date: 02 Jun 2014
Affected Mageia releases : 3 , 4
CVE: CVE-2014-3465 , CVE-2014-3466
Updated gnutls packages fix security vulnerabilities: 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).
