    HEWLETT-PACKARD COMPANY SECURITY BULLETIN: #034
    Originally issued: 15 March '02
---------------------------------------------------------------

The information in the following Security Bulletin 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
Bulletin as soon as possible.

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

---------------------------------------------------------------
PROBLEM:  Security vulnerability in at package.

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

DAMAGE:   Potential removal of non-mandatory attributes from objects

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

MANUAL ACTIONS: None

AVAILABILITY: The RPMs are available now.
 ---------------------------------------------------------------
 A. Background

    At(1) allows you to specify that a command will be run at a particular
    time (now or a specified time in the future).

    A vulnerability in at(1) exists where the submission of an at command
    could cause heap corruption, thus permitting arbitrary code to be
    run on the system.

 B. Fixing the problem

    Hewlett-Packard Company recommends that customers who have installed
    the at(1) package download the RPMs listed in the following Red Hat
    Security Advisory:

    2002-03-13    at (RHSA-2002-015)    Updated at package available

    http://www.redhat.com/support/errata/RHSA-2002-015.html

    To install the security bulletin 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 bulletin RPM.

           tripwire --check --interactive

    2. Install the bulletin RPM from the root account.

           rpm -F <bulletin RPM name>

    3. Update the tripwire database

           tripwire --check --interactive



    NOTE:
    The rpm -q <package name> command can be used to determine if the
    package is installed. Hewlett-Packard Company recommends applying the
    Security Bulletin 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.
