---------------------------------------------------------------------
                   Red Hat Security Advisory
Synopsis:          Updated LPRng packages fix psbanner vulnerability
Advisory ID:       RHSA-2003:142-01
Issue date:        2003-04-24
Updated on:        2003-04-24
Product:           Red Hat Linux
Keywords:          
Cross references:  
Obsoletes:         
CVE Names:         CAN-2003-0136
---------------------------------------------------------------------
1. Topic:
Updated LPRng packages resolving a temporary file vulnerability are now
available.
2. Relevant releases/architectures:
Red Hat Linux 7.1 - i386
Red Hat Linux 7.2 - i386, ia64
Red Hat Linux 7.3 - i386
Red Hat Linux 8.0 - i386
Red Hat Linux 9 - i386
3. Problem description:
LPRng is a print spooler.  LPRng includes a program, psbanner, that can be
used to produce Postscript banner pages to separate print jobs.  
A vulnerability has been found in psbanner, which creates a temporary file
with a known filename in an insecure manner.  An attacker could create a
symbolic link and cause arbitrary files to be written as the 'lp' user.
Note: psbanner is not used by the default Red Hat Linux LPRng configuration.
Users that have configured LPRng to use psbanner should install these
updated packages, which contain a patch so that psbanner does not create
the temporary file.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade.  Only those
RPMs which are currently installed will be updated.  Those RPMs which are
not installed but included in the list will not be updated.  Note that you
can also use wildcards (*.rpm) if your current directory only contains the
desired RPMs.
Please note that this update is also available via Red Hat Network.  Many
people find this an easier way to apply updates.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:
up2date
This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

These packages are GPG signed by Red Hat for security.  Our key is
available at http://www.redhat.com/solutions/security/news/publickey/
You can verify each package with the following command:
    
    rpm --checksig -v <filename>
If you only wish to verify that each package has not been corrupted or
tampered with, examine only the md5sum with the following command:
    
    md5sum <filename>
