Comodo Memory Firewall is a buffer overflow detection and prevention tool which provides the ultimate defence against one of the most serious and common attack types on the Internet – the buffer overflow attack. Comodo Memory Firewall protects against data theft, computer crashes and system damage by preventing most types of buffer overflow attacks. This type of attack occurs when a malicious program or script deliberately sends more data to its memory buffer than the buffer can handle. It is at this point that a successful attack can create a back door to the system though which a hacker can gain access. The product is aimed for system administrators as well as desktop users to protect their systems and detects suspicious code executions in the stack or the heap portions of the memory. Comodo Memory Firewall detects the following types of attack:

• Detection of Buffer Overflows which occur in the STACK memory,
• Detection of Buffer Overflows which occur in the HEAP memory,
• Detection of ret2libc attacks,
• Detection of corrupted/bad SEH Chains Free for Windows XP, Vista and Server 2003.
