That advice would be true if it properly implemented the defense known as Address Space Layout Randomization (ASLR).
This technique, called address space layout randomization (ASLR), stores data in different locations each and every time the application is run.
In basic address space layout randomization
(ASLR), the begin cope with of the code segment is randomized.
64-bit processes in general, and browser processes in particular, get significant security advantages by making Windows ASLR (Address Space Layout Randomization
"One of them in particular is Address Space Layout Randomization
. And in particular, they've added it to the kernel.
He cited one obstacle as address space layout randomization
, a function included in Windows Vista that rearranges the positions of key system code when a PC restarts.<p>But attackers searching for vulnerabilities in Microsoft products are as active as ever, he said.<p>One Chinese researcher at the forum demonstrated a tool for fuzz testing of software, a technique used by software vendors and attackers that involves feeding a program invalid data inputs to see what causes a crash.
Moving to a 64-bit process allows Chrome to use features such as High Entropy ASLR (address space layout randomization
) and improve defenses against JIT spraying, which should make the browser significantly more secure against some zero-day vulnerabilities.
Rakshasa's malware payload then proceeds to disable the NX (no-execute) bit, remove anti-SMM protections, and disable ASLR (address space layout randomization
According to his latest blog post, ASLR (or Address Space Layout Randomization
) featured introduced in Android 4.0 ICS has been finally "implemented" in the latest Android 4.1 Jelly Bean release.
