ASLR (Address Space Layout Randomization) is a form of data security used to randomize data on the Template:Wp to help prevent exploits from taking control of the system. It first appeared in Template:Wp.
Program and dyld
- On program load, the address space offset of the program is randomized between 0x0 and 0x100000
- It always falls on a 0x1000 page boundary
- dyld is included in this sliding section
- The system libraries are now stored in a big cache file, see
- This address randomized at boot time, in many possible places, higher in the address space than the program
- The functions retain a fixed offset to each other.
