▸ GLSA 201412-40 FLAC: User-assisted execution of arbitrary code this version unaffected normal remote 2014-12-26

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

Announced: 2014-12-26
Revised: 2014-12-26
Access: remote
Bugs: #530288
Advisory: https://security.gentoo.org/glsa/201412-40

Affected packages

Package	Arch	Vulnerable	Unaffected
media-libs/flac	*	< 1.3.1-r1	>= 1.3.1-r1

Background

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

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.
