+ <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>

+ All ImageMagick users should upgrade to the latest version:

+ <code>
+ # emerge sync
+
+ # emerge -pv ">=media-gfx/imagemagick-6.0.7.1"
+ # emerge ">=media-gfx/imagemagick-6.0.7.1"</code>

+ All imlib users should upgrade to the latest version:
