RHSA-2013:0588: Moderate: gnutls security update

First published: Mon Mar 04 2013(Updated: )

The GnuTLS library provides support for cryptographic algorithms and for<br>protocols such as Transport Layer Security (TLS).<br>It was discovered that GnuTLS leaked timing information when decrypting<br>TLS/SSL protocol encrypted records when CBC-mode cipher suites were used.<br>A remote attacker could possibly use this flaw to retrieve plain text from<br>the encrypted packets by using a TLS/SSL server as a padding oracle.<br>(CVE-2013-1619)<br>Users of GnuTLS are advised to upgrade to these updated packages, which<br>contain a backported patch to correct this issue. For the update to take<br>effect, all applications linked to the GnuTLS library must be restarted,<br>or the system rebooted.<br>
