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

of the GD routine that handles loading PNG image files.
A remote attacker could entice a user to load a carefully crafted PNG image

All GD users should upgrade to the latest version:
