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 B=F6hme 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
==========
