Address Space Layout Randomization
A runtime security measure that randomizes the memory addresses that programs load data and code into. Usually implemented at the Operating System level, this will change the location of loaded code at each boot for libraries that are nx compliant. ASLR Bypass is a technique typically achieved by exploiting a non nx compliant library in the context of an nx compliant operating system.
ASLR is implemented in Linux Kernel 2.6*, Windows XP SP3 and more recent (Vista and 7).
