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
——————————————————————-
1 media-libs/flac < 1.3.1-r1 >= 1.3.1-r1
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.
