For a decade, every major operating system has relied on a technique known as address space layout randomization to provide a first line of defense against malware attacks. By randomizing the computer memory locations where application code and data are loaded, ASLR makes it hard for attackers to execute malicious payloads when exploiting buffer overflows and similar vulnerabilities. As a result, exploits cause a simple crash rather than a potentially catastrophic system compromise.

Now, researchers have devised an attack that could spell the end of ASLR as the world knows it now.
