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.
