                   Red Hat, Inc. Red Hat Security Advisory

Synopsis:          Comprehensive Printing Update
Advisory ID:       RHSA-2001:138-10
Issue date:        2001-10-22
Updated on:        2001-10-31
Product:           Red Hat Linux
Keywords:          Omni printing ghostscript foomatic printconf
Cross references:  

1. Topic:

A collection of security fixes, bug fixes, and functionality updates,
including the Omni print drivers from IBM.

2. Relevant releases/architectures:

Red Hat Linux 7.2 - i386

3. Problem description:

This update addresses the following issues:

A printing security hole, whereby non-local users could print the contents
of any file on the system which the 'lp' user was capable of reading. This
was solved by giving Ghostscript a 'PARANOIDSAFER' mode, which will not
open external files.

A foomatic printing database bug, which caused all users of the 'stp'
driver, including virtually all Epson printers, to fail to print as a
result of miscalculated driver data.

A filtration problem, which caused many PCL and PJL printers to produce
garbage. This was solved by switching to the foomatic distributed
'lpdomatic' program for filtration.

A few printconf crashers in the new printconf-tui programme.

And in addition, this update adds the Omni print drivers from IBM, which
support an additional 300 printers.

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
desired RPMs.

After updating the rpms, you will need to restart your print server, by

/sbin/service lpd restart

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:


This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
