An updated xpdf package that fixes a buffer overflow security issue is now
available.

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

Description

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

A heap based buffer overflow bug was discovered in Xpdf. An attacker could
construct a carefully crafted PDF file that could cause Xpdf to crash or
possibly execute arbitrary code when opened. The Common Vulnerabilities and
Exposures project assigned the name CVE-2006-0301 to this issue.

Users of Xpdf should upgrade to this updated package, which contains a
backported patch to resolve these issues.

Red Hat would like to thank Dirk Mueller for reporting this issue and
providing a patch.
