==== 1. In Focus: Add VMware Player to Your Security Toolkit 
   by Mark Joseph Edwards, News Editor, mark at ntsecurity / net

VMware is a tool that lets you run various OSs as virtual machines 
(VMs) on a single computer. The Windows IT Pro Web site has many 
articles about VMware, which you can find listed at

I've been testing VMware Workstation lately, and last week I woke up to 
a pleasant surprise. While doing a little early morning blog surfing, I 
came across a blog I hadn't read before called Wubble. As it turns out, 
the blog author, Philip Langdale, works at VMware. 

In a blog entry, "VMs for Everyone!" (at the first URL below), I 
learned that during the VMworld 2005 conference in Las Vegas (Oct. 18-
20), VMware released a new standalone tool, VMware Player (at the 
second URL below). If you've used VMware Workstation, the VMware 
servers, or VMware ACE (Assured Computing Environment), then you know 
how incredibly useful VMware is. The new Player (which will also ship 
with the upcoming VMware Workstation 5.5) is equally useful for two 
particular reasons. First, it lets you run existing VMs created by 
other VMware tools and supports VMs created with Microsoft Virtual 
Server as well as Symantec LiveState Recovery snapshots. Second, it's 

As with many free tools, VMware Player has some limitations. For 
example, you can't create new VMs and you can't add new hardware to a 
VM. You can learn about other limitations in VMware's comparison chart.

Even with some limitations, VMware Player is a great offering. As you 
might suspect, you can use it to run Windows, Linux, Novell NetWare, 
Sun Microsystems Solaris, and FreeBSD as guest OSs. Another nice thing 
is that if you don't have a VM to run in VMware Player or don't want to 
create one, you can download one from VMware's Web site. Available are 
VMs for Novell Linux Desktop, Novell SUSE Linux Enterprise Server, and 
Red Hat Enterprise Linux, plus several other VMs provided by various 
application vendors. VMware also provides a VM based on Ubuntu Linux 
that's configured as a Browser Appliance and designed to let you surf 
the Internet while protecting your underlying OS from malware. 

If you've run a honeypot or a honeymonkey or had to test various 
software and tools, you probably know (or can imagine) how using a VM 
can be of great benefit. For example, you can build your honeypot on 
any supported OS and run it inside a VM. Then if the honeypot is 
compromised, it's not a problem--just shut down the VM and restart it 
again, and any changes made by an intruder are gone. The same goes for 
running a honeymonkey or testing spyware and other forms of malware. 
Plus, you can run Linux-based security tools on a Windows desktop by 
loading them into a Linux-based VM. With VMware Player, you can extend 
your use to other systems quickly and easily--and that's what makes 
VMware Player a great addition for your security toolkit. Check it out.

Recent Security Vulnerabilities
   If you subscribe to this newsletter, you also receive Security 
Alerts, which inform you about recently discovered security 
vulnerabilities. You can also find information about these 
discoveries at

Exchange Server 2003 SP2 Improves Security
   Microsoft released Exchange Server 2003 Service Pack 2 (SP2), which 
includes a number of new features, including some security 
enhancements. Learn about the new features in a news story on our Web 
site (at the first URL below), in Paul Robichaux's article "Exchange 
Server 2003 SP2 Ships" (at the second URL below), and in Tony Redmond's 
article "Exploring Exchange 2003 Service Pack 2" (at the third URL 

Multiple Vulnerabilities in Oracle Products
   Multiple high-risk vulnerabilities exist in Oracle9i Database 
Server, Oracle Database Server 10g, and many other Oracle products. 
They consist of one buffer overflow condition and numerous possible SQL 
injection attacks, many of which could be exploited by an intruder to 
gain complete control of the products. Oracle released a Critical Patch 
Update (at the URL below) to correct many (but not all) of the 

Buffer Overflow Vulnerability in Snort and Sourcefire
   Internet Security Systems (ISS) X-Force discovered a buffer overflow 
vulnerability in Snort, which according to ISS also affects 
Sourcefire--the commercial version of Snort. The vulnerability exists 
in the Back Orifice preprocessor; systems that don't use Back Orifice 
aren't affected. Snort 2.4.3 was released to correct the problem. For 
more details about the problem in Snort, read the announcement on the 
Snort.org Web site (first URL below) and ISS's advisory at the second 
URL below. At the time of this writing, no information was available 
about updates to Sourcefire. 

Secure Your Wireless Network
   Along with the benefits of wireless networks comes a need to keep 
them secure. John Howie gives you a look at some practical steps you 
can take to secure your wireless networks, methods to automate 
configuration-setting deployment, and tools you can use to probe for 
unsecured and unauthorized wireless networks.

Security Matters Blog: New Linksys Wireless Adapter Puts a Wi-Fi 
Scanner in Your Pocket
   by Mark Joseph Edwards, http://list.windowsitpro.com/t?ctl=179A0:4FB69

The new Linksys Wireless-G USB Network Adapter with Wi-Fi Finder is a 
really slick and innovative product. It has a built-in wireless scanner 
to detect available networks, and it works as a standalone unit so you 
can detect 802.11b/g networks before you power up your laptop. Having 
one of these is sort of like having NetStumbler in a device the size of 
a pack of gum! Check it out in this blog entry.
