Red Hat Security Advisory 2014-0288-01
Posted Mar 12, 2014
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2014-0288-01 - The GnuTLS library provides support for cryptographic algorithms and for protocols such as Transport Layer Security. 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. This issue was discovered by Nikos Mavrogiannopoulos of the Red Hat Security Technologies Team.

3. Description:

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.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the
Red Hat Network to apply this update are available at
https://access.redhat.com/site/articles/11258

5. Bugs fixed (https://bugzilla.redhat.com/):

1069865 - CVE-2014-0092 gnutls: incorrect error handling in certificate verification (GNUTLS-SA-2014-2)
