<background>
<p>
PEAR Net_Traceroute is an OS independent wrapper class for executing
traceroute calls from PHP.
</p>
</background>
<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 &quot;&gt;=dev-php/PEAR-Net_Traceroute-0.21.2&quot;</code>
</resolution>
