---------------------------------------------------------------
    HEWLETT-PACKARD COMPANY SECURITY BULLETIN: #021
    Originally issued: 25 January '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:  Heap corruption vulnerability in the at package

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

DAMAGE:   Potential unauthorized execution of commands with root privileges

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

MANUAL ACTIONS: None

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

    A malicious local user could exploit an overflow in at(1) to gain
    root privileges.

 B. Fixing the problem

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

    2002-01-22  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
    product 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.
