The remote host is affected by the vulnerability described in GLSA-200911-06
(PEAR Net_Traceroute: Command injection)
Pasquale Imperato reported that the $host parameter to the traceroute()
function in Traceroute.php is not properly sanitized before being
passed to exec().
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.
Ensure that all data that is passed to the traceroute() function is
properly shell escaped (for instance using the escapeshellcmd()
