  <background>
    <p>Gnash is a GNU flash movie player that supports many SWF features.</p>
  </background>
  <description>
    <p>Multiple vulnerabilities have been found in Gnash:</p>
    
    <ul>
      <li>The "nsPluginInstance::setupCookies()" function in plugin.cpp creates
        world-readable cookies with predictable file names (CVE-2011-4328).
      </li>
      <li>The "GnashImage::size()" function in GnashImage.h contains an integer
        overflow error which could cause a heap-based buffer overflow
        (CVE-2012-1175).
      </li>
    </ul>
  </description>
  <impact type="normal">
    <p>A remote attacker could entice a user to open a specially crafted SWF
      file, possibly resulting in execution of arbitrary code or a Denial of
      Service condition. Furthermore, a local attacker may be able to obtain
      sensitive information.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All Gnash users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=www-plugins/gnash-0.8.10-r2"
    </code>
