(RHSA-2014:0288) Important: gnutls security update

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

It was discovered that GnuTLS did not correctly handle certain errors that
could occur during the verification of an X.509 certificate, causing it to
incorrectly report a successful verification. An attacker could use this
flaw to create a specially crafted certificate that could be accepted by
GnuTLS as valid for a site chosen by the attacker. (CVE-2014-0092)

This issue was discovered by Nikos Mavrogiannopoulos of the Red Hat
Security Technologies Team.

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.
