Title: 3proxy HTTP Proxy Request Buffer Overflow Vulnerability
Severity: HIGH
Description:
3proxy is a free proxy server for Linux/UNIX and Windows.
The application is prone to a buffer-overflow vulnerability because it fails to adequately bounds-check user-supplied data before copying it to an insufficiently sized buffer.
The issue occurs when the application processes transparent requests containing excessive data; an attacker may trigger this vulnerability with an overly large HTTP transparent request.
Attackers can exploit this issue to cause denial-of-service conditions and possibly to execute arbitrary code with the privileges of the application.
Few technical details are currently unavailable. This BID will be updated when more information emerges.
3proxy 0.5 to 0.5.3g and 0.6b-devel before 20070413 are vulnerable to this issue.
Affected Products:
- 3proxy 3proxy 0.5
- 3proxy 3proxy 0.5.3g
- 3proxy 3proxy 0.6b devel 20061014
- Gentoo net-proxy/3proxy 0.5.3g
