Who is Vulnerable?
Apple CUPS 1.3.5 and prior
Vulnerability Description
A heap overflow vulnerability has been discovered in Apple’s Common Unix Printing System (CUPS). The Common Unix Printing System (CUPS) is a modular printing system for Unix-like operating systems that allows a computer to act as a print server. A computer running CUPS is a host that can accept print jobs from client computers, process them, and send them to the appropriate printer. A remote attacker may exploit this issue to cause a denial of service condition on a target system.
Vulnerability Details
The vulnerability is due to a boundary error in CUPS when handling incoming CGI requests. A remote attacker may exploit this issue by sending a malicious CGI request to a target system. Successful exploitation of this vulnerability will allow the attacker to execute arbitrary code on the vulnerable system.

Protection Overview
By enabling this protection, IPS-1 will detect and block malformed CGI requests.
