Catdoc is a MS Word file decoding tool that doesn't attempt to analyze file formatting (it just extracts readable text), but is able to handle all versions of Word and convert character encodings. A Tcl/Tk graphical viewer is also included. It can also read RTF files and convert Excel and PowerPoint files.
Tenable Nessus is a world-leader in active vulnerability scanners. It features high-speed discovery, configuration auditing, asset profiling, sensitive data discovery, and vulnerability analysis of your security posture. Nessus scanners may be distributed throughout an entire enterprise, inside DMZs, and across physically separate networks. It is free of charge for personal use in a non-enterprise environment.
omnisode generates a Ruby program to use long Taylor series to solve systems of ordinary differential equations. It generates code to solve the equations in either Maple or Maxima. Using the Taylor series, estimates are made of the location and order of poles. It has been greatly re-worked the last few years, and tested quite a bit recently. Support may be extended to other languages in the future.
The audit package contains the user-space utilities for creating audit rules, as well as for storing, searching, and generating reports from the audit records generated by the audit subsystem in the Linux 2.6 kernel and higher. It has a real-time plugin interface for event analysis and remote logging of events.
radare2 aims to create a complete, portable, multi-architecture, Unix-like toolchain for reverse engineering. It is composed of a hexadecimal editor (radare) with a wrapped I/O layer supporting multiple backends for local/remote files, debugger (OS X, BSD, Linux, W32), stream analyzer, assembler/disassembler (rasm) for x86, ARM, PPC, m68k, Java, MSIL, and SPARC, code analysis modules, and scripting facilities. It also has a bindiffer named radiff, base converter (rax), a shellcode development helper (rasc), a binary information extractor supporting PE, Mach0, ELF, class, etc. named rabin, and a block-based hash utility called rahash. Radare was rewritten as radare2, and the old version is only maintained for bugfixes.
libjpeg-turbo is a high-speed version of libjpeg for x86 and x86-64 processors. It uses SIMD instructions (MMX, SSE, SSE2) to accelerate baseline JPEG compression and decompression. libjpeg-turbo is generally 2-4 times as fast as the unmodified version of libjpeg. It also includes a wrapper library for the TurboJPEG API used by VirtualGL and TurboVNC. It was originally based on libjpeg/SIMD but has improved support for Mac OS X, 64-bit platforms, 32-bit and big endian pixel formats (RGBA/BGRA/ABGR/ARGB), accelerated Huffman encoding/decoding, and various other fixes.
PC/SC-Proxy allows for access to PC/SC daemons on remote machines. There are two use cases. It can be used with thin clients and a terminal server to make the session access readers connected to the thin client. In this case, the address of the remote PC/SC service is taken from the login information (utmp). The second use case is when applications running inside a virtual machine (e.g. VirtualBox) need access to card readers of the host machine without disturbing operations on the host itself.
