GLSA-200411-07 : Proxytunnel: Format string vulnerability

critical Nessus Plugin ID 15612

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.

Solution

All Proxytunnel users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=net-misc/proxytunnel-1.2.3'
