Protects your computer against 90%+ of Buffer Overflow attacks The Comodo Memory Guardian Beta will protect your computer against 90%+ of Buffer Overflow attacks. With this solution, users are protected from "drive by" download attacks whereby a website injects malware onto a users PC. It is expected that this solution will be integrated into the Comodo Firewall toward the end of the year.
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.
