Updated packages fix PostScript and PDF security issue

Updated packages for gv and ggv fix a local buffer overflow
when reading malformed PDF or PostScript(R) files.

[Updated 16 April 2003]
Added packages for Red Hat Linux on IBM iSeries and pSeries systems.

Both gv and ggv are applications which use the Ghostscript PostScript
interpreter to display PostScript and PDF documents under the X Window
System.

Zen Parse found a local buffer overflow in gv version 3.5.8 and earlier.

Under this vulnerability, an attacker can create a carefully crafted,
malformed PDF or PostScript file that, when viewed using gv, executes
arbitrary commands on the system.

Because ggv contains code derived from gv, it has the same vulnerability.

All users of gv and ggv are advised to upgrade to these errata packages to
correct this vulnerability.

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.
