Synopsis
========

A heap-based buffer overflow in SWFTools could result in the execution
of arbitrary code.

Background
==========

SWFTools is a collection of SWF manipulation and generation utilities
written by Rainer Böhme and Matthias Kramm.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  media-gfx/swftools           <= 0.9.1                 Vulnerable!
    -------------------------------------------------------------------
     NOTE: Certain packages are still vulnerable. Users should migrate
           to another package if one is available or wait for the
           existing packages to be marked stable by their
           architecture maintainers.

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

Integer overflow errors in the "getPNG()" function in png.c and the
"jpeg_load()" function in jpeg.c could cause a heap-based buffer
overflow.

Impact
======

A remote attacker could entice a user to open a specially crafted PNG
or JPEG file, 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
==========

Gentoo discontinued support for SWFTools. We recommend that users
unmerge swftools:

  # emerge --unmerge "media-gfx/swftools"

References
