JERSEY CITY, N.J., September 19, 2007 - In its continuing commitment to keep users PCs safe from malware, Comodo today announced an important set of free diagnostic tests that will help users understand how vulnerable their computers are to buffer overflow attacks. Buffer overflow attacks can take many forms, including stack attacks, heap attacks and ret2libc attacks. In each case, the goal is to destabilize or crash a computer system by deliberately causing a buffer overflow - creating the opportunity for the hacker to then run malicious code and even gain control of the entire operating system.
Buffer overflow attacks are emerging as one of the Internet's most sinister mechanisms for injecting malware onto a user's computer. New "drive by download" attacks occur when a visitor navigates to a site that injects malware onto the PC, often by exploiting the vulnerability operative in the memory buffer. In fact, according to Secunia.com - a security information resource, 3 of the top 10 most searched threats are related to buffer overflow attacks.
From a technical perspective, there are three variants of buffer overflow attacks that are very prevalent on the Internet today:
Comodo created its free diagnostic tests to help users understand how well prepared they are to defend against these types of attacks. Each test is a small non-destructive program that deliberately attempts to by-pass the current measures of existing security software. Based on the results of these tests, users can then take remedial action including downloading Comodo's free solutions such as its award winning Comodo Firewall Pro and Comodo Memory Guardian, a new solution (now in BETA) effective at stopping 90%+ of buffer overflow attacks in both 32 bit and 64 bit environments.
" Users should be able to test if their security products such as anti-virus and firewall can protect them from a buffer overflow attack, " said Melih Abdulhayoglu, CEO and Chief Security Architect of Comodo." These attacks are now very widespread and are especially harmful for users because drive-by-download attacks extensively utilize the buffer overflow to inject malware to user's machines. With our combination of free solutions, user can stay safe despite these prevalent threats. "
