Synopsis
=======

The PNG image decoding routines in the GD library contain an integer overflow that may allow execution of arbitrary code with the rights of the program decoding a malicious PNG image.



Background
=========

The GD graphics library is an open source library which allows programmers to easily generate PNG, JPEG, GIF and WBMP images from many different programming languages.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/gd < 2.0.32 >= 2.0.32

Description
==========

infamous41md found an integer overflow in the memory allocation procedure of the GD routine that handles loading PNG image files.

Impact
=====

A remote attacker could entice a user to load a carefully crafted PNG image file in a GD-powered application, or send a PNG image to a web application which uses GD PNG decoding functions. This could potentially lead to execution of arbitrary code with the rights of the program loading the image.

Workaround
=========

There is no known workaround at this time.

Resolution
=========

All GD users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/gd-2.0.32"
