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"
