Vulnerability Assessment Details

RHSA-2002-124: xchat

Vulnerability Assessment Summary
Check for the version of the xchat packages

Detailed Explanation for this Vulnerability Assessment

A security issue in XChat permits a malicious server to execute arbitrary
commands.

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 rights 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.

[update 14 Aug 2002]
