Execute Bit Support
Intel's Execute Disable Bit functionality can prevent certain classes of malicious
"buffer overflow" attacks when combined with a supporting operating system.
This functionality allows the processor to classify areas in memory by where
application code can execute and where it cannot. When a malicious worm
attempts to insert code in the buffer, the processor disables code execution,
preventing damage or worm propagation.
