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

or potentially execute arbitrary code when opened.  
(CVE-2007-4352, CVE-2007-5392, 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.
