CRITICAL:
Less critical

IMPACT:
Privilege escalation

http://secunia.com/advisories/product/20835/

DESCRIPTION:
Some security issues have been reported in PDFjam, which can be
exploited by malicious, local users to perform certain actions with
escalated privileges.

The security issues are caused due to the "pdf90", "pdfjoin", and
"pdfnup" scripts using temporary files in an insecure manner. This
can be exploited to overwrite arbitrary files via symlink attacks.

SOLUTION:
Restrict local access to trusted users only.
