      Title:  Updated enscript packages available

TEXT





---------------------------------------------------------------
    HEWLETT-PACKARD COMPANY SECURITY BULLETIN: #019
    Originally issued: 23 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:  Security flaw in enscript.

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

DAMAGE:   Potential overwrite of files.

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

MANUAL ACTIONS: None

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

    GNU Enscript converts ASCII files to PostScript and spools
    generated PostScript output to the specified printer or leaves it
    in a file. A flaw has been found which may allow attackers to
    exploit enscript temporary file creation to overwrite arbitrary
    files on the system. The enscript package is not included in the
    default installation of HP Secure OS Software for Linux release
    1.0.

 B. Fixing the problem

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

    2002-01-17 enscript (RHSA-2002-012) Updated enscript packages fix
    temporary file handling vulnerabilities
 
    http://www.redhat.com/support/errata/RHSA-2002-012.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.
