Summary
Red Hat Security Advisory: : : : Updated xchat packages fix "/dns" vulnerability
Notes
Topic
A security vulnerability in XChat allows a malicious server to execute
arbitrary commands.
[Updated 11 July 2003]
Added packages for Red Hat Linux on IBM iSeries and pSeries systems.
Details
XChat is a popular cross-platform IRC client.
Versions of XChat prior to 1.8.9 do not filter the response from an IRC
server when a "/dns" query is executed. Because XChat resolves hostnames by
passing the configured resolver and hostname to a shell, an IRC server may
return a maliciously formatted response that executes arbitrary commands
with the privileges of the user running XChat.
All users of XChat are advised to update to these errata packages
containing XChat version 1.8.9, which is not vulnerable to this issue.
