xpdf security update

An updated xpdf package that correctly fixes several integer overflows is
now available.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

The xpdf package is an X Window System-based viewer for Portable Document
Format (PDF) files.

During a source code audit, Chris Evans and others discovered a number of
integer overflow bugs that affected all versions of Xpdf. An attacker could
construct a carefully crafted PDF file that could cause Xpdf to crash or
possibly execute arbitrary code when opened. This issue was assigned the
name CAN-2004-0888 by The Common Vulnerabilities and Exposures project
(cve.mitre.org). RHSA-2004:592 contained a fix for this issue, but it was
found to be incomplete and left 64-bit architectures vulnerable. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2005-0206 to this issue.

All users of xpdf should upgrade to this updated package, which contains
backported patches to resolve these issues.
