Comodo Memory Gurdian is a buffer overflow detecion and protection tool which provides the ultimate defense against one of the most serious and common attack types on the Internet.

What is a Buffer Overflow attack?
-------------------------------------
...excerpt from http://en.wikipedia.org/wiki/Buffer_overflow
"
In computer security and programming, a buffer overflow, or buffer overrun, is a programming error which may result in a memory access exception and program termination, or in the event of the user being malicious, a possible breach of system security.

A buffer overflow is an anomalous condition where a process attempts to store data beyond the boundaries of a fixed-length buffer. The result is that the extra data overwrites adjacent memory locations. The overwritten data may include other buffers, variables and program flow data and may cause a process to crash or produce incorrect results. They can be triggered by inputs specifically designed to execute malicious code or to make the program operate in an unintended way. As such, buffer overflows cause many software vulnerabilities and form the basis of many exploits. Sufficient bounds checking by either the programmer or the compiler can prevent buffer overflows."
