Linux Memory Forensics: Using mprotect() with PROT_NONE

In case you didn't catch it on the Volatility Labs blog, I found an interesting bug that we've had in the framework since we've had Linux support. If you've had cases that involved Linux samples and plugins like linux_yarascan, linux_strings etc, you might want to update to the latest code and have another look over those samples. Of course, there's no reason to think that a piece of malware might have used this trick and used a sigsegv handler to access the data, but the idea has been around for years...
