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"
