CentOS Errata and Security Advisory CESA-2012:0429

The GnuTLS library provides support for cryptographic algorithms and for
protocols such as Transport Layer Security (TLS).

A flaw was found in the way GnuTLS decrypted malformed TLS records. This
could cause a TLS/SSL client or server to crash when processing a
specially-crafted TLS record from a remote TLS/SSL connection peer.
(CVE-2012-1573)

A boundary error was found in the gnutls_session_get_data() function. A
malicious TLS/SSL server could use this flaw to crash a TLS/SSL client or,
possibly, execute arbitrary code as the client, if the client passed a
fixed-sized buffer to gnutls_session_get_data() before checking the real
size of the session data provided by the server. (CVE-2011-4128)

Red Hat would like to thank Matthew Hall of Mu Dynamics for reporting
CVE-2012-1573.

Users of GnuTLS are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. For the update to take
effect, all applications linked to the GnuTLS library must be restarted, or
the system rebooted.
