Severity: high
Exploitable: remote
Date: April 22, 2007
Bug(s): #174429
ID: 200704-17

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

Package: net-proxy/3proxy
Vulnerable: < 0.5.3h
Unaffected: >= 0.5.3h
Architectures: All supported architectures


Description

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

Impact

A remote attacker could send a specially crafted transparent request to the proxy, resulting in the execution of arbitrary code with privileges of the user running 3proxy.

Workaround

There is no known workaround at this time.

Resolution

All 3proxy users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-proxy/3proxy-0.5.3h"
