GLSA-200411-07 : Proxytunnel: Format string vulnerability

This script is Copyright (C) 2004-2014 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-200411-07
(Proxytunnel: Format string vulnerability)

Florian Schilhabel of the Gentoo Linux Security Audit project found a
format string vulnerability in Proxytunnel. When the program is started in
daemon mode (-a [port]), it improperly logs invalid proxy answers to
syslog.

Impact :

A malicious remote server could send specially crafted invalid answers to
exploit the format string vulnerability, potentially allowing the execution
of arbitrary code on the tunnelling host with the rights of the Proxytunnel
process.

Workaround :

You can mitigate the issue by only allowing connections to trusted remote
servers.

# emerge --sync
# emerge --ask --oneshot --verbose '>=net-misc/proxytunnel-1.2.3'
