I read that overflow DEP protection, which used to be available in some other tool, was rolled into Comodo Firewall. However, after installing Comodo Firewall, I see that my system is still vulnerable to Stack & Heap execution and Ret2Libc vulnerability according to BO Tester.
I have Comodo Firewall, Anti-Virus, and BO Clean installed.
PS. Why the ambiguity between naming BO Clean and BO Tester, two unrelated products. What does BO stand for in either instance? Hint: Most people still think “Back Orifice”.
