<p>
ImageMagick is a suite of image manipulation utilities and libraries used
for a wide variety of image formats. imlib is a general image loading and
rendering library.
</p>
</background>
<description>
<p>
Due to improper bounds checking, ImageMagick and imlib are vulnerable to a
buffer overflow when decoding runlength-encoded bitmaps. This bug can be
exploited using a specially-crafted BMP image and could potentially allow
remote code execution when this image is decoded by the user.
</p>
</description>
<impact type="normal">
<p>
A specially-crafted runlength-encoded BMP could lead ImageMagick and imlib
to crash or potentially execute arbitrary code.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All ImageMagick users should upgrade to the latest version:
</p>
<code>
# emerge sync
# emerge -pv ">=media-gfx/imagemagick-6.0.7.1"
# emerge ">=media-gfx/imagemagick-6.0.7.1"</code>
<p>
All imlib users should upgrade to the latest version:
</p>
<code>
# emerge sync
# emerge -pv ">=media-libs/imlib-1.9.14-r2"
# emerge ">=media-libs/imlib-1.9.14-r2"</code>
<p>
All imlib2 users should upgrade to the latest version:
</p>
<code>
# emerge sync
# emerge -pv ">=media-libs/imlib2-1.1.2"
# emerge ">=media-libs/imlib2-1.1.2"</code>
