Definition Edit

Address space layout randomization (ASLR) is a computer security technique involved in protection from buffer overflow attacks. To prevent an attacker from reliably jumping to a particular exploited function in memory (for example), ASLR involves randomly arranging the positions of key data areas of a program, including the base of the executable and the positions of the stack, heap, and libraries, in a process's address space.
