  <background>
    <p>The X PixMap image format is an extension of the monochrome X BitMap
      format specified in the X protocol, and is commonly used in traditional X
      applications.

  <description>
    <p>An integer overflow was discovered in libXpm’s src/CrDatFrI.c file. 
      On 64 bit systems, this allows an overflow to occur on 32 bit integers
      while parsing XPM extensions in a file.
    </p>
  </description>
  <impact type="normal">
    <p>A remote attacker, by enticing a user to process a specially crafted XPM
      file, could execute arbitrary code with the privileges of the process or
      cause a Denial of Service condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All libXpm users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=x11-libs/libXpm-3.5.12"
    </code>
