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.
