3. Problem description:

The Common UNIX Printing System (CUPS) provides a portable printing layer
for UNIX(R) operating systems.

Alin Rad Pop discovered several flaws in the handling of PDF files. An
attacker could create a malicious PDF file that would cause CUPS to crash
or potentially execute arbitrary code when printed.
(CVE-2007-4352, CVE-2007-5392, CVE-2007-5393)

Alin Rad Pop discovered a flaw in in the way CUPS handles certain IPP tags.
A remote attacker who is able to connect to the IPP TCP port could send a
malicious request causing the CUPS daemon to crash. (CVE-2007-4351)

A flaw was found in the way CUPS handled SSL negotiation. A remote attacker
capable of connecting to the CUPS daemon could cause CUPS to crash.
(CVE-2007-4045)

All CUPS users are advised to upgrade to these updated packages, which
contain backported patches to resolve these issues.
