Mandriva Linux Security Advisory : gnutls (MDVSA-2014:108)

This script is Copyright (C) 2014 Tenable Network Security, Inc.


Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

Description :

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).
