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.
