SWFTools: User-assisted execution of arbitrary code

Background

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

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"

NOTE: Users could upgrade to “>=media-gfx/swftools-0.9.1”, however these packages are not currently stable.
