A security issue in XChat allows 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 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.
[update 14 Aug 2002] Previous packages pushed were not signed, this update replaces the packages with signed versions
