"Updated poppler packages that fix a security issue in PDF handling are
now available for Red Hat Enterprise Linux 5.

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

Poppler is a PDF rendering library, used by applications such as
evince.

Maurycy Prodeus discovered an integer overflow flaw in the processing
of PDF files. An attacker could create a malicious PDF file that would
cause an application linked with poppler to crash or potentially
execute arbitrary code when opened. (CVE-2007-3387)

All users of poppler should upgrade to these updated packages, which
contain a backported patch to resolve this issue."
