[GLSA]

Gentoo Linux Security Advisory

Title: SWFTools: User-assisted execution of arbitrary code (GLSA 201204-05)
Severity: normal
Exploitable: remote
Date: April 17, 2012
Updated: April 18, 2012
Bug(s): #332649
ID: 201204-05

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: media-gfx/swftools
Vulnerable: <= 0.9.1
Architectures: All supported architectures


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:
