The information in the following Security Advisory should be acted
upon as soon as possible.  Hewlett-Packard Company will not be
liable for any consequences to any customer resulting from the
customer's failure to fully implement instructions in this Security
Advisory as soon as possible.

Because the vulnerability does not require a Hewlett-Packard Secure OS
1.0 patch or re-packaging of the RPM affected by the advisory, the
RPMs have not been produced or tested by Hewlett-Packard.

PROBLEM:  Bug in CTCP PING handling code.

PLATFORM: Any system running HP Secure OS software for Linux Release 1.0

DAMAGE:   Potential execution of commands on IRC server

SOLUTION: Apply the appropriate RPMs (see section B below)


AVAILABILITY: The RPMs are available now.
 A. Background

    Xchat is an IRC client. A vulnerability exists in the CTCP PING
    handling code that could potentially be used by an attacker to
    execute commands on the IRC server masquerading as the vulnerable
    client. Xchat is not included in the default installation of HP
    Secure OS Software for Linux.

 B. Fixing the problem

    Hewlett-Packard recommends that customers download the RPMs
    listed in the following Red Hat Security Advisory:

    2002-01-14 xchat (RHSA-2002-005) Updated xchat packages are


    To install the security advisory RPMs, use the following sequence
    of commands:

    1. If you use the tripwire product, we recommend that you run a
       a consistency check and fix any violations before installing
       the security advisory RPM.

           tripwire --check --interactive

    2. Install the advisory RPM from the root account.

           rpm -F <advisory RPM name>

    3. Update the tripwire database

           tripwire --check --interactive

    The rpm -q <package name> command can be used to determine if the
    product is installed. Hewlett-Packard recommends applying the
    security advisory fixes to installed packages only. The -F option
    to the RPM installer will only apply the fix if the package is
    currently installed on the system. Dependent RPMs can be found by
    using the "Find Latest RPMs" search facility at
    http://www.redhat.com/apps/download. To find the latest dependent
    RPM enter the RPM's name in the "By Keyword" box.
