Description Mark J. Cox 2004-05-11 09:56:40 UTC

A flaw in the XChat's Socks-5 proxy code could allow arbitrary code
execution.  To exploit this flaw an attacker would need to create a
malicious socks-5 proxy that the victim connects to.

This issue was public on Mon, 5 Apr 2004

http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=2004-0409 links to
http://mail.nl.linux.org/xchat-announce/2004-04/msg00000.html for 
more information.

"XChat's Socks-5 proxy code is vulnerable to a remote exploit. To
successfully exploit the code, you would need to enable socks5 
traversal (default off) and connect to the attacker's own custom
proxy server.

"If you never intend to use a Socks5 proxy, you are not affected at
all by this issue."

Fixed already for earlier releases by Fedora Legacy (bug #152706), but now
needed for FC2.
