RHEL 2.1 : xchat (RHSA-2002:124)

This script is Copyright (C) 2004-2016 Tenable Network Security, Inc.

Synopsis :

The remote Red Hat host is missing a security update.

Description :

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

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

Solution :
