The Openwall Linux kernel patch is a collection of security "hardening" features for the Linux kernel which can stop most 'cookbook' buffer overflow exploits. The patch can also add more privacy to the system by restricting access to parts of /proc so that users may not see what others are doing. Also tightens down file descriptors 0, 1, and 2, implements process limits and shared memory destruction.

Changes: Fixed an x86-specific Linux kernel vulnerability where local users could abuse a binary compatibility interface (lcall) to kill processes not belonging to them, including system processes.
