  <background>
    <p>gdk-pixbuf is an image loading library for GTK+.</p>
  </background>
  <description>
    <p>Two vulnerabilities have been found in gdk-pixbuf:</p>
    
    <ul>
      <li>The "gdk_pixbuf__gif_image_load()" function in io-gif.c fails to
        properly handle certain return values from subroutines (CVE-2011-2485).
      </li>
      <li>The "read_bitmap_file_data()" function in io-xbm.c contains an
        integer overflow error (CVE-2012-2370).
      </li>
    </ul>
  </description>
  <impact type="normal">
    <p>A remote attacker could entice a user to open a specially crafted image
      in an application linked against gdk-pixbuf, possibly resulting in Denial
      of Service. 
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All gdk-pixbuf users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=x11-libs/gdk-pixbuf-2.24.1-r1"
    </code>
    
    <p>Packages which depend on this library may need to be recompiled. Tools
      such as revdep-rebuild may assist in identifying some of these packages.
    </p>
  </resolution>
