Abstract:
A system-wide service can simultaneously harden multiple running JITs, for example by hooking into the memory protections of a target operating system and randomizing newly generated code on the fly when marked as executable. Some embodiments preserve the contents of the calling stack, presenting each JIT with the illusion that it is executing its own generated code.
