high Nessus Plugin ID 51354

Language:

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated libvpx 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 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 libvpx packages provide the VP8 SDK, which allows the encoding and decoding of the VP8 video codec, commonly used with the WebM multimedia container file format.

An integer overflow flaw, leading to arbitrary memory writes, was found in libvpx. An attacker could create a specially crafted video encoded using the VP8 codec that, when played by a victim with an application using libvpx (such as Totem), would cause the application to crash or, potentially, execute arbitrary code. (CVE-2010-4203)

All users of libvpx are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the update, all applications using libvpx must be restarted for the changes to take effect.

Solution

Update the affected packages.
