This morning, I just committed and pushed to GitHub my first major modification to Oliver Pinter’s existing ASLR patches. In order to support legacy applications that won’t work with ASLR, I’ve made it so that ASLR works on a per-jail basis. If you want global protection, you can have ASLR set in your global jail. You can stick the non-compatible application in a jail that has ASLR turned off. That way, you can provide security for everything but the applications that don’t work with ASLR enabled. Additionally, if you are a jails-based hosting provider and your customer doesn’t want ASLR, the customer can turn it off [him/her]self. My next goal is to get execbase randomization working. This will require a bit of additional research. Once execbase randomization is working, we’ll have a technically complete ASLR implementation!
