pWhois Layer Four Traceroute 3.x vulnerability

Vulnerability Note VU#946652

Original Release Date: 2011-04-04 | Last Revised: 2011-04-04

Overview

Given a specific set of command line arguments, Layer Four Traceroute (lft) will produce a segmentation fault leading to a possible privilege escalation vulnerability.

Description

pWhois Layer Four Traceroute 3.x contains a vulnerability when parsing command line arguments. Earlier versions of Layer Four Traceroute may also be vulnerable. Some distributions that package Layer Four Traceroute are not vulnerable because they do not install the 'lft' binary SETUID root.

Impact

If Layer Four Traceroute is installed SETUID root, a local attacker may be able to exploit the vulnerability for privilege escalation.

Solution

Apply an Update

Upgrade to Layer Four Traceroute 3.3 or later.

Workaround


If upgrading to the latest version is not possible, do not install Layer Four Traceroute SETUID root. This will limit the application functionality for unprivileged users.
