Information stored in RAM, he says, is “randomized, making it more difficult to exploit.” That’s not the case with the Mac software, according to Caceres. Wikipedia zegt hierover: Address space randomization hinders some types of security attack by preventing an attacker being able to easily predict target addresses. For example attackers trying to execute return-to-libc attacks must locate the code to be executed; while other attackers trying to execute shellcode injected on the stack have to first find the stack. In both cases, the related memory addresses are obscured from the attackers; these values have to be guessed, and a mistaken guess is not usually recoverable due to the application crashing. Als OS X hier niet aan doet, zal Vista dus veiliger met zijn geheugen omgaan. But, he adds, Apple’s Unix roots, more frequent operating system release cycle and ...
