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.

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

<impact type="normal">
<p>
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.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All GD users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/gd-2.0.32"</code>
</resolution>
