#2358: Windows ASLR is not enabled for tor.exe, and DEP should be forced
-------------------------+--------------------------------------------------
 Reporter:  special      |       Owner:     
     Type:  enhancement  |      Status:  new
 Priority:  normal       |   Milestone:     
Component:  Tor Client   |     Version:     
 Keywords:               |      Parent:     
-------------------------+--------------------------------------------------
 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
 [http://msdn.microsoft.com/en-us/library/bb736299(v=VS.85).aspx
 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.
