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

medium Nessus Plugin ID 74417

Language:

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).

Solution

Update the affected packages.
