John The Ripper 1.7.4
Posted Dec 30, 2009
Authored by Solar Designer | Site openwall.com

John the Ripper is a fast password cracker, currently available for many flavors of Unix (11 are officially supported, not counting different architectures), DOS, Win32, and BeOS. Its primary purpose is to detect weak Unix passwords, but a number of other hash types are supported as well.

Changes: The word mangling rules engine has been enhanced in many ways, including addition of support for back-references and "parallel" ranges to the preprocessor, the notion of numeric variables, more rule commands and reject flags, as well as performance improvements. The default rulesets have been revised to make use of the new features, for speed, to produce fewer duplicates, and to generate additional kinds of candidate passwords. The idle priority emulation code has been optimized for lower overhead, and the Idle setting has been enabled by default.

Openwall Linux Kernel Patch 2.4.37.7-ow1
Posted Nov 18, 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: The patch has been updated to Linux 2.4.37.7.

Also tightens down file descriptors 0, 1, and 2, implements process limits and shared memory destruction.

Changes: The patch has been updated to Linux 2.4.37.6. A fix for a typographical error in one of the information leak fixes included into 2.4.37.6 has been added.

John The Ripper 1.7.3.4
Posted Sep 21, 2009
Authored by Solar Designer | Site openwall.com

John the Ripper is a fast password cracker, currently available for many flavors of Unix (11 are officially supported, not counting different architectures), DOS, Win32, and BeOS. Its primary purpose is to detect weak Unix passwords, but a number of other hash types are supported as well.

Changes: "make check" has been implemented (for Unix-like systems only), primarily for use by packages of JtR. The "--test" option will now take an optional argument - the duration of each benchmark in seconds. The section .note.GNU-stack has been added to all assembly files to avoid the stack area unnecessarily being made executable on Linux systems that use this mechanism. Some very minor bugs that did not affect normal operation have been fixed.

Also tightens down file descriptors 0, 1, and 2, implements process limits and shared memory destruction.

Changes: Besides being an update to the 2.4.37.3 kernel release, this revision of the patch introduces an additional security hardening measure where the kernel would no longer allow the "personality" feature (which is needed to support some program binaries from other operating systems) to be abused to bypass the vm.mmap_min_addr restriction via SUID-root programs with a certain class of design errors in them.
