Synopsis
========

A double free vulnerability has been discovered in libfpx that allows
remote attackers to cause a Denial of Service.

Background
==========

A library for manipulating FlashPIX images.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  media-libs/libfpx           < 1.3.1_p6               >= 1.3.1_p6

Description
===========

A double free vulnerability has been discovered in the Free_All_Memory
function in jpeg/dectile.c.

Impact
======

A remote attacker could entice a user to open a specially crafted FPX
image using an application linked against libfpx, possibly resulting in
a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All libfpx users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=media-libs/libfpx-1.3.1_p6"

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