FreeBSD : proxytunnel -- format string vulnerability (50744596-368f-11d9-a9e7-0001020eed82)

Critical Nessus Plugin ID 37117


The remote FreeBSD host is missing a security-related update.


A Gentoo Linux Security Advisory reports :

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.

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.


Update the affected package.
