-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: gnutls security update Advisory ID: RHSA-2014:0247-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-0247.html Issue date: 2014-03-03 CVE Names: CVE-2009-5138 CVE-2014-0092 ===================================================================== 1. Summary: Updated gnutls packages that fix two security issues are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: RHEL Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 3. Description: The GnuTLS library provides support for cryptographic algorithms and for protocols such as Transport Layer Security (TLS). It was discovered that GnuTLS did not correctly handle certain errors that could occur during the verification of an X.509 certificate, causing it to incorrectly report a successful verification. An attacker could use this flaw to create a specially crafted certificate that could be accepted by GnuTLS as valid for a site chosen by the attacker. (CVE-2014-0092) A flaw was found in the way GnuTLS handled version 1 X.509 certificates. An attacker able to obtain a version 1 certificate from a trusted certificate authority could use this flaw to issue certificates for other sites that would be accepted by GnuTLS as valid. (CVE-2009-5138) The CVE-2014-0092 issue was discovered by Nikos Mavrogiannopoulos of the Red Hat Security Technologies Team. Users of GnuTLS are advised to upgrade to these updated packages, which correct these issues. For the update to take effect, all applications linked to the GnuTLS library must be restarted. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/site/articles/11258 5.
