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'
