Severity:	normal
Title:	FLAC: User-assisted execution of arbitrary code
Date:	12/26/2014
Bugs:	#530288
ID:	201412-40

Synopsis

A buffer overflow vulnerability in FLAC could lead to execution of arbitrary code or Denial of Service.

Background

The Free Lossless Audio Codec (FLAC) library is the reference implementation of the FLAC audio file format.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-libs/flac	< 1.3.1-r1	>= 1.3.1-r1	All supported architectures

Description

A stack-based buffer overflow flaw has been discovered in FLAC.

Impact

A remote attacker could entice a user to open a specially crafted .flac file using an application linked against FLAC, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All FLAC users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=media-libs/flac-1.3.1-r1"

Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying these packages.
