CentOS Errata and Security Advisory CESA-2013:0883

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

It was discovered that the fix for the CVE-2013-1619 issue released via
RHSA-2013:0588 introduced a regression in the way GnuTLS decrypted TLS/SSL
encrypted records when CBC-mode cipher suites were used. A remote attacker
could possibly use this flaw to crash a server or client application that
uses GnuTLS. (CVE-2013-2116)

Users of GnuTLS are advised to upgrade to these updated packages, which
correct this issue. For the update to take effect, all applications linked
to the GnuTLS library must be restarted.
