<p>
GraphicsMagick is a collection of tools to read, write and
manipulate images in many formats.

<description>
<p>
The SetImageInfo function was found vulnerable to a format string
mishandling. Daniel Kobras discovered that the handling of "%"-escaped
sequences in filenames passed to the function is inadequate in
ImageMagick GLSA 200602-06 and the same vulnerability exists in
GraphicsMagick.
</p>
</description>
<impact type="normal">
<p>
By feeding specially crafted file names to GraphicsMagick an
attacker can crash the program and possibly execute arbitrary code with
the privileges of the user running GraphicsMagick.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All GraphicsMagick users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=media-gfx/graphicsmagick-1.1.7&quot;</code>
</resolution>
