DescriptionFrom Red Hat Security Advisory 2013:0588 :
Updated gnutls packages that fix one security issue are now available for Red Hat Enterprise Linux 5 and 6.
The Red Hat Security Response Team has rated this update as having moderate 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.
The GnuTLS library provides support for cryptographic algorithms and for protocols such as Transport Layer Security (TLS).
It was discovered that GnuTLS leaked timing information when decrypting TLS/SSL protocol encrypted records when CBC-mode cipher suites were used. A remote attacker could possibly use this flaw to retrieve plain text from the encrypted packets by using a TLS/SSL server as a padding oracle. (CVE-2013-1619)
Users of GnuTLS are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. For the update to take effect, all applications linked to the GnuTLS library must be restarted, or the system rebooted.
