Openwall Linux Kernel Patch

Openwall Linux Kernel Patch
Posted Aug 23, 2009
Authored by Solar Designer | Site openwall.com

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: Besides being an update to the 2.4.37.5 kernel release, this revision of the patch adds a fix for the sigaltstack local information leak affecting 64-bit kernel builds.)
