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.
