-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: gnutls security update Advisory ID: RHSA-2014:0595-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-0595.html Issue date: 2014-06-03 CVE Names: CVE-2014-3466 ===================================================================== 1. Summary: Updated gnutls packages that fix one security issue are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having Important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64 3. Description: The GnuTLS library provides support for cryptographic algorithms and for protocols such as Transport Layer Security (TLS). A flaw was found in the way GnuTLS parsed session IDs from ServerHello messages of the TLS/SSL handshake. A malicious server could use this flaw to send an excessively long session ID value, which would trigger a buffer overflow in a connecting TLS/SSL client application using GnuTLS, causing the client application to crash or, possibly, execute arbitrary code. (CVE-2014-3466) Red Hat would like to thank GnuTLS upstream for reporting this issue. Upstream acknowledges Joonas Kuorilehto of Codenomicon as the original reporter. Users of GnuTLS are advised to upgrade to these updated packages, which correct this issue. 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.
