Description

Updated xpdf packages that fix several security issues are now available for Red Hat Enterprise Linux 2.1.

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

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

Alin Rad Pop discovered a flaw in the handling of PDF files. An attacker could create a malicious PDF file that would cause Xpdf to crash, or potentially execute arbitrary code when opened. (CVE-2007-5393)

A flaw was found in the t1lib library, used in the handling of Type 1 fonts. An attacker could create a malicious file that would cause Xpdf to crash, or potentially execute arbitrary code when opened. (CVE-2007-4033)

Users are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.
