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

A flaw was discovered in the way GnuTLS handles NULL characters in certain
fields of X.509 certificates. If an attacker is able to get a
carefully-crafted certificate signed by a Certificate Authority trusted by
an application using GnuTLS, the attacker could use the certificate during
a man-in-the-middle attack and potentially confuse the application into
accepting it by mistake. (CVE-2009-2730)

Users of GnuTLS are advised to upgrade to these updated packages, which
contain a backported patch that corrects this issue.");
