    <p>bip is a multi-user IRC proxy with SSL support.</p>

  <description>
    <p>Multiple vulnerabilities have been discovered in bip:</p>
    
    <ul>
      <li>Uli Schlachter reported that bip does not properly handle invalid
        data during authentication, resulting in a daemon crash
        (CVE-2010-3071).
      </li>
      <li>Julien Tinnes reported that bip does not check the number of open
        file descriptors against FD_SETSIZE, resulting in a stack buffer
        overflow (CVE-2012-0806).
      </li>
    </ul>
  </description>
  <impact type="high">
    <p>A remote attacker could exploit these vulnerabilities to execute
      arbitrary code with the privileges of the user running the bip daemon, or
      cause a Denial of Service condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All bip users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=net-irc/bip-0.8.8-r1"
    </code>
    
    <p>NOTE: The CVE-2010-3071 flaw was already corrected in an earlier version
      of bip and is included in this advisory for completeness.
    </p>
