RHSA-2013:0588: Moderate: gnutls security update
The GnuTLS library provides support for cryptographic algorithms and forprotocols such as Transport Layer Security (TLS).It was discovered that GnuTLS leaked timing information when decryptingTLS/SSL protocol encrypted records when CBC-mode cipher suites were used.A remote attacker could possibly use this flaw to retrieve plain text fromthe 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, whichcontain a backported patch to correct this issue. For the update to takeeffect, all applications linked to the GnuTLS library must be restarted,or the system rebooted.
