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.

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)

backported patches to resolve these issues."
