    <p>
    ImageMagick is an application suite to manipulate and convert
    images. It is often used as a utility backend by web applications like
    forums, content management systems or picture galleries.

  <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. This is a
    new vulnerability that is not addressed by GLSA 200503-11.
    </p>
  </description>
  <impact type="normal">
    <p>
    By feeding specially crafted file names to ImageMagick, an
    attacker can crash the program and possibly execute arbitrary code with
    the privileges of the user running ImageMagick.
    </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 --ask --oneshot --verbose &quot;&gt;=media-gfx/imagemagick-6.2.5.5&quot;</code>
  </resolution>
