An updated xpdf package that fixes multiple security issues is now
available for Red Hat Enterprise Linux 4.

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

execute arbitrary code when opened. (CVE-2009-0791, CVE-2009-1188,
CVE-2009-3604, CVE-2009-3606, CVE-2009-3608, CVE-2009-3609)

Users are advised to upgrade to this updated package, which contains a
