 ///  File Name: StMichael_LKM-0.11.tar.gz
Description:
StMichael is a LKM that attempts to detect and divert attempts to install a kernel-module backdoor into a running linux system. This is done by monitoring the init_module and delete_module process for changes in the system call table. Detects most modern LKM's, including KIS.
Author:Tim Lawless
Homepage:http://www.sourceforge.net/projects/stjude
Changes:Addition of Self Integrity Checks to Detect Attacks Against StMichael itself. Added of configuration options to hard-code memory offsets into the source instead of discovery during load time, permitting loading of Stmichael from an initrd, before init spawns and the filesystems are mounted.

 ///  File Name: linux-2.4.30-ow3.tar.gz
Description:
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.
Author:Solar Designer

 ///  File Name: multiadm-1.0.4.tbz2
Description:
The MultiAdmin security framework kernel module provides a means to have multiple root users with unique UIDs. This bypasses collation order problems with NSCD, allows you to have files with unique owners, and allows you to track the quota usage for every real user. It also implements a sub-admin, a partially restricted root user who has full read-only access to most subsystems, but write rights only to a limited subset, for example writing to files or killing processes only of certain users.

Description:
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.
Author:Solar Designer
Homepage:http://www.openwall.com/linux
Changes:2.4.28-ow1 fixes a number of security-related bugs, including the local root ELF loader vulnerabilities discovered by Paul Starzetz, a race condition with reads from Unix domain sockets (potential local root), and smbfs support vulnerabilities discovered by Stefan Esser (remote DoS by a malicious smbfs server; potential: remote root by a malicious smbfs server).

 ///  File Name: ext2hide-0.99.9.tar.gz
Description:
ext2hide allows the user to save and restore an arbitrary number of files to and from the reserved space in an ext2/3 filesystem's primary and backup superblocks. Using ext2hide, you can use this reserved section to store an arbitrary number of files, where they will be completely invisible to normal filesystem utilities, but still residing in permanent storage on disk. This can be useful for passwords, public keys, anything you like.
