Moderate: gnutls security update
Security Advisory: Moderate
Updated gnutls packages that fix a security issue are now available for Red
Hat Enterprise Linux 5.
This update has been rated as having moderate security impact by the Red
Hat Security Response Team.
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.
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
