    <p>
    The SOCKS 5 proxy code in XChat is vulnerable to a remote exploit.
    Users would have to be using XChat through a SOCKS 5 server, enable
    SOCKS 5 traversal which is disabled by default and also connect to an
    attacker's custom proxy server.
    </p>
  </description>
  <impact type="low">
    <p>
    This vulnerability may allow an attacker to run arbitrary code within
    the context of the user ID of the XChat client.
    </p>
  </impact>
  <workaround>
    <p>
    A workaround is not currently known for this issue. All users are
    advised to upgrade to the latest version of the affected package.

  </workaround>
  <resolution>
    <p>
    All XChat users should upgrade to the latest stable version:

    # emerge -pv "&gt;=net-irc/xchat-2.0.8-r1"
    # emerge "&gt;=net-irc/xchat-2.0.8-r1"</code>
    <p>
    Note that users of the gtk1 version of xchat (1.8.*) should upgrade to
    xchat-1.8.11-r1:
    </p>
    <code>
    # emerge sync
