Gentoo Linux Security Advisory

Title: FLAC: User-assisted execution of arbitrary code (GLSA 201412-40)
Severity: normal
Exploitable: remote
Date: December 26, 2014
Bug(s): #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: media-libs/flac
Vulnerable: < 1.3.1-r1
Unaffected: >= 1.3.1-r1
Architectures: 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:
Code:
# 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.
