Windows ASLR is not enabled for tor.exe, and DEP should be forced
To mitigate the potential impact of vulnerabilities, the Tor executable for Windows should be built with support for Address Space Layout Randomization. See http://www.ziki.com/fr/gcouprie+37899/post/enable-dep-and-aslr-with-mingw+10897502 for a potentially dated explanation of how this could be done for MinGW.
Additionally, Tor should permanently enable DEP by calling SetProcessDEPPolicy at startup. By default, non-server versions of Windows only apply DEP to processes that opt-in with this call, and it prevents the possibility of malicious code causing the process to opt out.
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
