A vulnerability in the Windows kernel can be triggered via SMB in Microsoft Windows versions ranging from Windows 2000 through to Windows 7. This vulnerability allows an attacker to trigger a kernel pool corruption by sending a specially crafted SMB_COM_TRANSACTION2 request. Successful exploitation of this issue may result in remote code execution with kernel privileges, while failed attempts will result in a denial of service condition.

RPM Finder Project version 1.2 is a utility that works much like the rpmfind.net site. It supports RedHat and Mandrake Linux.

The Linux Security Auditing Tool (LSAT) is a post install security auditor for Linux/Unix. It checks many system configurations and local network settings on the system for common security/config errors and for packages that are not needed. It (for now) works under Linux (x86: Gentoo, RedHat, Debian, Mandrake; Sparc: SunOS (2.x), Redhat sparc, Mandrake Sparc; Apple OS X).

The Bastille Hardening program locks down an operating system, configuring the system for increased security. It currently supports Red Hat, Fedora Core, Red Hat Enterprise, SuSE, SuSE Enterprise, Mandrake, Debian, and Gentoo, HP-UX, and Apple's Mac OS X. Screenshot available here..

vthrottle is an implementation of an SMTP throttling engine for Sendmail servers, based upon M. Williamson's mechanisms, as described in his 2003 Usenix Security paper. It allows the administrator to control how much email users and hosts may send, hindering the rapid spread of viruses, worms, and spam. Exceptions can be made using a whitelist mechanism, which can be generated manually or with the included tool vmeasure.

If you are a security engineer, a researcher, a hacker or just someone who keeps your ear to the ground when it comes to computer security, chances are you have seen the name Michal Zalewski. He has been responsible for an abundance of tools, research, proof of concepts and helpful insight to many over the years. He recently released a book called "The Tangled Web - A Guide To Securing Modern Web Applications".

Normally, when I read books about securing web applications, I find many parallels where authors will give an initial lay of the land, dictating what technologies they will address, what programming languages they will encompass and a decent amount of detail on vulnerabilities that exist along with some remediation tactics. Such books are invaluable for people in this line of work, but there is a bigger picture that needs to be addressed and it includes quite a bit of secret knowledge rarely divulged in the security community. You hear it in passing conversation over beers with colleagues or discover it through random tests on your own. But rarely are the oddities documented anywhere in a thorough manner.

Before we go any further, let us take a step back in time. Well over a decade ago, the web was still in its infancy and an amusing vulnerability known as the phf exploit surfaced. It was nothing more than a simple input validation bug that resulted in arbitrary code execution. The average hacker enjoyed this (and many more bugs like it) during this golden age. At the time, developers of web applications had a hard enough time getting their code to work and rarely took security implications into account. Years later, cross site scripting was discovered and there was much debate about whether or not a cross site scripting vulnerability was that important. After all, it was an issue that restricted itself to the web ecosystem and did not give us a shell on the server. Rhetoric on mailing lists mocked such findings and we (Packet Storm) received many emails saying that by archiving these issues we were degrading the quality of the site. But as the web evolved, people starting banking online, their credit records were online and before you knew it, people were checking their social network updates on their phone every five minutes. All of a sudden, something as small as a cross site scripting vulnerability mattered greatly.

To make the situation worse, many programs were developed to support web-related technologies. In the corporate world, being first to market or putting out a new feature in a timely fashion trumphs security. Backwards compatibility that feeds poor design became a must for any of the larger browser vendors. The "browser wars" began and everyone had different ideas on how to solve different issues. To say web-related technologies brought many levels of complexity to the modern computing experience is a great understatement. Browser-side programming languages, such as JavaScript, became a playground for hackers. Understanding the Document Object Model (DOM) and the implications of poorly coded applications became one of those lunch discussions that could cause you to put your face into your mashed potatoes. Enter "The Tangled Web".

This book puts some very complicated nuances in plain (enough) english. It starts out with Zalewski giving a brief synopsis of the security industry and the web. Breakdowns of the basics are provided and it is written in a way that is inviting for anyone to read. It goes on to cover a wide array of topics inclusive to the operation of browsers, the protocols involved, the various types of documents handled and the languages supported. Armed with this knowledge, the reader is enabled to tackle the next section detailing browser security features. As the author puts it, it covers "everything from the well-known but often misunderstood same-origin policy to the obscure and proprietary zone settings of Internet Explorer". Browsers, it ends up, have a ridiculous amount of odd dynamics for even the simplest acts. The last section wraps things up with upcoming security features and various browser mechanisms to note.

I found it a credit to the diversity of the book that technical discussion could also trail off to give historical notes on poor industry behavior. When it noted DNS hijacking by various providers it reminded me of the very distinct and constantly apparent disconnect between business and knowledge of technology. When noting how non-HTTP servers were being leveraged to commit cross site scripting attacks, Zalewski also made it a point to note how the Internet Explorer releases only have a handful of prohibited ports but all other browsers have dozens that they block. The delicate balance of understanding alongside context is vital when using information from this book and applying it to design.

Every page offers some bit of interesting knowledge that dives deep. It takes the time to note the odd behaviors small mistakes can cause and also points out where flawed security implementations exist. This book touches on the old and the new and many things other security books have overlooked. Another nice addition is that it provides security engineering cheatsheets at the end of each chapter. To be thorough, it explains both the initiatives set out by RFCs while it also documents different paths various browser vendors have taken in tackling tricky security issues. Google's Chrome, Mozilla's Firefox, Microsoft's Internet Explorer, Apple's Safari and Opera are compared and contrasted greatly throughout this book.

In my opinion, the web has become a layer cake over the years. New shiny technologies and add-ons have been thrown into the user experience and with each of them comes a new set of security implications. One-off findings are constantly discovered and documented (and at Packet Storm we try to archive every one of them), but this is the first time I have seen a comprehensive guide that focuses on everything from cross-domain content inclusion to content-sniffing. It is the sort of book that should be required reading for every web developer.
