3proxy: Buffer overflow

3proxy: Buffer overflow A vulnerability has been discovered in 3proxy allowing for the remote execution of arbitrary code. 3proxy April 22, 2007 April 22, 2007: 01 174429 remote 0.5.3h 0.5.3h

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

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

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.

There is no known workaround at this time.

All 3proxy users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-proxy/3proxy-0.5.3h"
