    <p>
    PEAR Net_Traceroute is an OS independent wrapper class for executing
    traceroute calls from PHP.

  <description>
    <p>
    Pasquale Imperato reported that the $host parameter to the traceroute()
    function in Traceroute.php is not properly sanitized before being
    passed to exec().
    </p>
  </description>
  <impact type="high">
    <p>
    A remote attacker could exploit this vulnerability when user input is
    passed directly to PEAR Net_Traceroute in a PHP script, possibly
    resulting in the remote execution of arbitrary shell commands with the
    privileges of the user running the affected PHP script.
    </p>
  </impact>
  <workaround>
    <p>
    Ensure that all data that is passed to the traceroute() function is
    properly shell escaped (for instance using the escapeshellcmd()
    function).
    </p>
  </workaround>
  <resolution>
    <p>
    All PEAR Net_Traceroute users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=dev-php/PEAR-Net_Traceroute-0.21.2"</code>
  </resolution>
