Debian Linux Security Advisories - The version of X-Chat that was distributed with Debian GNU/Linux 2.2 has a vulnerability in the URL handling code: when a user clicks on a URL X-Chat will start netscape to view its target. However it did not check the URL for shell metacharacters, and this could be abused to trick xchat into executing arbitraty commands. This has been fixed in version 1.4.3-0.1, and we recommend you upgrade your xchat package(s) immediately.

Package : xchat
Problem type : remote exploit
Debian-specific: no

The version of X-Chat that was distributed with Debian GNU/Linux 2.2
has a vulnerability in the URL handling code: when a user clicks on
a URL X-Chat will start netscape to view its target. However it
did not check the URL for shell metacharacters, and this could be
abused to trick xchat into executing arbitraty commands.

This has been fixed in version 1.4.3-0.1, and we recommend you
upgrade your xchat package(s) immediately.

Update: the powerpc packages mentioned in the first release of this
advisory were linked with a version of libgtk that is not available
in Debian GNU/Linux 2.2. They have been recompiled with the correct
version and reuploaded.
