OK, the answer to the title of this blog is clearly NO. Let's take a bug that causes a program to crash as soon as it starts running. Unless the program is used to protect something else, crashing it as soon as it starts is probably the safest thing you can do (you are guaranteed that it won't leak anything!). But, barring such obvious exceptions, is it possible that all bugs can somehow be utilized to breach security? I don't know the answer. However, when I see something like this, I get nervous. Kris Kaspersky has demonstrated that it's possible to use bugs in Intel's CPUs in order to carry out attacks that cannot be patched. This is another suprise attack, utilizing bugs that until now were never considered "security flaws". So, are all bugs security flaws? I would guess that most definitely have the potential...
