3. Description:

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

Martin von Gagern discovered a flaw in the way GnuTLS verified certificate chains provided by a server. A malicious server could use this flaw to spoof its identity by tricking client applications using the GnuTLS library to trust invalid certificates. (CVE-2008-4989)

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