  <description>
    <p>Two vulnerabilities have been discovered in GNU cpio:</p>
    
    <ul>
      <li>The list_file function in GNU cpio contains a heap-based buffer
        overflow vulnerability (CVE-2014-9112)
      </li>
      <li>A directory traversal vulnerability has been found in GNU cpio
        (CVE-2015-1197)
      </li>
    </ul>
  </description>
  <impact type="normal">
    <p>A remote attacker may be able to entice a user to open a specially
      crafted archive using GNU cpio, possibly resulting in execution of
      arbitrary code, a Denial of Service condition, or overwriting arbitrary
      files. 
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All GNU cpio users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=app-arch/cpio-2.11-r3"
    </code>
