  <description>
    <p>A heap-based buffer overflow exists when handling Shockwave Flash files.</p>
  </description>
  <impact type="normal">
    <p>A remote attacker could entice a user to open a specially crafted Flash
      file using a package linked against Win32 Codecs, possibly resulting in
      execution of arbitrary code with the privileges of the process or a
      Denial of Service condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>Gentoo has discontinued support for Win32 Codecs. We recommend that
      users unmerge Win32 Codecs:
    </p>
    
    <code>
      # emerge --unmerge "media-libs/win32codecs"
    </code>
