Address Space Layout Randomization (ASLR) is a security technique used to prevent exploitation of memory corruption vulnerabilities. It randomizes the memory addresses where key data areas of a process (such as the base of the executable and the location of libraries, heap, and stack) are loaded. This makes it more difficult for attackers to predict the location of target code or data, hindering the effectiveness of techniques like buffer overflows and return-to-libc attacks.
