RHEL 6 : gnutls (RHSA-2013:0588)

medium Nessus Plugin ID 65005

Language:

Synopsis

The remote Red Hat host is missing a security update for gnutls.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2013:0588 advisory.

 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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL gnutls package based on the guidance in RHSA-2013:0588.
