Summary: 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 RHEL Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 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. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/FAQ_58_10188 5.
