In short, ASLR is working as intended and th e configuration issue described by CERT/CC only affects applications where the EXE does not already opt-in to ASLR. In this blog post, we will explain the configuration issue that CERT/CC encountered and describe wo rk arounds to enable the desired behavior. Last week, the CERT/CC published an advisory describing some unexpected behavior they observed when enabling system-wide mandatory Address Space Layout Randomization ( ASLR ) using Windows Defender Exploit Guard (WDEG) and EMET on Windows 8 and above. 64-bit system and application processes can take advantage of a vastly increased memory space, which makes it even more difficult for malware to. Windows 10 applies ASLR holistically across the system and increases the level of entropy many times compared with previous versions of Windows to combat sophisticated attacks such as heap spraying.
