Updated Xpdf packages fix security vulnerability

Updated Xpdf packages are now available that fix a vulnerability in which a
maliciously-crafted pdf document could run arbitrary code.

Xpdf is a viewer for Portable Document Format (PDF) files.

During an audit of CUPS, a printing system, Zen Parsec found an integer
overflow vulnerability in the pdftops filter. Since the code for pdftops
is taken from the Xpdf project, all versions of Xpdf including 2.01 are
also vulnerable to this issue. An attacker could create a PDF
file that could execute arbitrary code. This could would have the same
access privileges as the user who viewed the file with Xpdf.

All users of Xpdf are advised to upgrade to these erratum packages. For
Red Hat Linux 8.0 we have included new packages based on Xpdf 1.01 with a
patch to correct this issue. For Red Hat Linux 7.0, 7.1, 7.2, and 7.3 we
have upgraded Xpdf to version 1.00 with a patch to correct this issue. For
Red Hat Linux 6.2 we have upgraded Xpdf to version 0.92 with a patch to
correct this issue.

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.
