 SECURITY BULLETIN: HPSBTL0210-0073
 Originally issued: 15 OCT 2002
 -----------------------------------------------------------------

NOTICE: There are no restrictions for distribution of this Bulletin
provided that it remains complete and intact.

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 customer's failure to fully implement instructions in this
Security Bulletin as soon as possible.

 ------------------------------------------------------------------
PROBLEM: Security vulnerability in tetex (dvips)

IMPACT: Possible execution of arbitrary commands

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

SOLUTION: Apply the appropriate patch.

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

    TeTeX is an implementation of TeX for Linux or UNIX systems.
    TeX takes a text file and a set of formatting commands as input
    and creates a typesetter-independent .dvi (DeVice Independent)
    file as output.

    The dvips utility converts DVI format into PostScript(TM), and
    is used in Red Hat Linux as a print filter for printing DVI
    files.

    dvips contains a vulnerability allowing print users to execute
    arbitrary commands.

 B. Recommended solution

    Hewlett-Packard Company recommends that customers who have
    installed tetex download the RPMs listed in the following
    Red Hat Security Advisory in the section labeled "Red Hat
    Linux 7.1".

    2002-10-08 RHSA-2002:194 Command execution vulnerability
                              in dvips

    http://rhn.redhat.com/errata/RHSA-2002-194.html

    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

    NOTE:
    The rpm -q <package name> command can be used to determine if
    the package 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.
