Address space layout randomization

Address space layout randomization (ASLR) is a computer security technique involved in preventing exploitation of memory corruption vulnerabilities. In order to prevent an attacker from reliably redirecting code execution to a particular exploited function in memory, ASLR randomly arranges the address space positions of key data areas of a process…
