[Reversemode advisory] Computer Associates HIPS Drivers - multiple local privilege escalation vulnerabilities.

Computer Associates "Host Intrusion Prevention System" Engine Drivers
are prone to multiple local privilege escalation vulnerabilities.

arbitrary code with kernel privileges.

Two drivers are affected, kmxstart.sys and kmxfw.sys. These drivers hook

State: Unpatched.
Products affected: CA Internet Security, CA Personal Firewall…
