RedHat: Moderate: gnutls security update
Summary
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.
