On September 19, 2007, IT security and management solutions provider Comodo (comodo.com) pronounced that it is offering a set of free diagnostic tests that will help users understand how vulnerable their computers are to buffer overflow attacks, which are emerging as one of the Internet's most dangerous devices for uploading malware onto a user's computer.

The three kinds of buffer overflow attacks that are commonly found on the Internet today are stack overflow, heap overflow and Ret2libc attacks. Comodo's free diagnostic tests helps users understand how well prepared they are to defend against these attacks.

Each test is a small non-destructive program that deliberately attempts to bypass the current measures of existing security software. Based on the results of the tests, users can take the proper action, including downloading Comodo's free solutions such as its Comodo Firewall Pro and Comodo Memory Guardian, a new solution now in BETA that effectively prevents more than 90 percent of buffer overflow attacks in both 32 bit and 64 bit environments.

Melih Abdulhayoglu, CEO and chief security architect of Comodo, said: "Users should be able to test if their security products such as anti-virus and firewall can protect them from a buffer overflow attack. 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."
