Explanation EXEC SHIELD: Exec Shield is a security patch for the Linux kernel that adds an NX bit to x86 CPUs. It was developed by Ingo Molnar of Red Hat, and is used as a part of Fedora Core 1, 2 and 3. Exec Shield attempts to flag data memory as non-executable and program memory as non-writeable. This suppresses many security exploits, such as those stemming from buffer overflows and other techniques relying on overwriting data and inserting code into those structures. Exec Shield also supplies some address space layout randomization for the mmap() and heap base.
