GLSA-200911-06 : PEAR Net_Traceroute: Command injection

This script is Copyright (C) 2009-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

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().

Impact :

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.

Workaround :

Ensure that all data that is passed to the traceroute() function is
properly shell escaped (for instance using the escapeshellcmd()
function).

Solution :

All PEAR Net_Traceroute users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=dev-php/PEAR-Net_Traceroute-0.21.2'

Risk factor :

Critical / CVSS Base Score : 10.0
