RHSA-2015:0767 - Important: flac security update

Synopsis

Important: flac security update

Type/Severity

Security Advisory Important

Topic

Updated flac packages that fix two security issues are now available for Red Hat Enterprise Linux 6 and 7.

Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Description

The flac packages contain a decoder and an encoder for the FLAC (Free Lossless Audio Codec) audio file format.

A buffer overflow flaw was found in the way flac decoded FLAC audio files. An attacker could create a specially crafted FLAC audio file that could cause an application using the flac library to crash or execute arbitrary code when the file was read. (CVE-2014-9028)

A buffer over-read flaw was found in the way flac processed certain ID3v2 metadata. An attacker could create a specially crafted FLAC audio file that could cause an application using the flac library to crash when the file was read. (CVE-2014-8962)

All flac users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing the update, all applications linked against the flac library must be restarted for this update to take effect.

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.
