    <p>Wee Enhanced Environment for Chat (WeeChat) is a light and extensible
      console IRC client.
    </p>
  </background>
  <description>
    <p>Two vulnerabilities have been discovered in WeeChat:</p>
    
    <ul>
      <li>The hook_process() function does not properly handle shell expansions
        (CVE-2012-5534).
      </li>
      <li>WeeChat does not properly decode colors which could cause a
        heap-based buffer overflow (CVE-2012-5854).
      </li>
    </ul>
  </description>
  <impact type="normal">
    <p>A remote attacker could entice a user to open a specially crafted script
      or send messages with specially crafted colors, 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>All WeeChat users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=net-irc/weechat-0.3.9.2"
    </code>
