Abstract
A method for timely address space randomize includes loading a code region from a program binary to a first location within the address space, detecting, during execution of the program, an output-input call pair from the program and, in response to detecting the output-input call pair from the program: selecting a second location within the address space to move the code region to, determining memory locations of one or more references to the code region, updating the values of the references in memory based on the second location and using annotation information within the program binary, and moving the code region to the second location within the address space.
