Synopsis
========

A vulnerability has been discovered in 3proxy allowing for the remote
execution of arbitrary code.

Background
==========

3proxy is a multi-protocol proxy, including HTTP/HTTPS/FTP and SOCKS
support.

Affected packages
=================

Description
===========

The 3proxy development team reported a buffer overflow in the logurl()
function when processing overly long requests.

Impact

of the user running 3proxy.

Workaround
