Technical Tidbits™

Posts Tagged ‘oxymoron’

As much as I preach and preach in my courses about Microsoft and their lame excuse for security – whether within their code or in an alleged security application – people continue to get suckered into the delusional image Microsoft presents about knowing what’s best for you in security.

I’ve posted before about this so I won’t rehash the same old arguments. I’m just going to illustrate YET ANOTHER reason why I continue to harp on the subject in an effort to educate users about the subject of their security.

I was reading my RSS feeds and ran across the current Microsoft Security Bulletin summary for May. Don’t know why I felt compelled to read it – I just did.

Published on May 13th (so I’m a little behind but give me a break, our PC Security course just launched!), the bulletin summary contains a “Moderate” severity listing hidden under the lovely plus signs [+] they use liberally to discourage people from actually reading the details.

First, if you click the link to see just what a Moderate severity rating is, you are taken to a page that explains the rating in such terms as: exploitability, mitigated, default configuration, and auditing. Yeah, right! I’m sure you all understand that right?

But okay, let’s give them a break since the technical writer was probably a nerd.

Moving on….. I click the nefarious plus sign [+] to expose the underlying dirt that M$ doesn’t want us to see. And what do I get?

This bulletin title:

Vulnerabilities in Microsoft Malware Protection Engine Could Allow Denial of Service (952044)

Imagine that! A vulnerability in another Microsoft product!

Okay, so I’m not surprised by that, but what interests me is the fact that it’s in the Malware Protection Engine of their product. So, hmmmmm, I wonder… “could that be one of their so-called security products?” I ask myself as I start reading further.

I hit the jackpot! Not only is it one of their so-called security products, it’s a good many of them!

Specifically, the affected software is: Windows Live OneCare, Microsoft Antigen, Microsoft Windows Defender, Microsoft Forefront Security.

So now I’m REALLY interested! I clicked the link to go to the actual full bulletin – which is located here if you want to follow the whole story with me: http://www.microsoft.com/technet/security/Bulletin/MS08-029.mspx

And once again tackling the plus signs [+] I get to see the “down and dirty” details of what’s really going on here!

There are two specific CVE references to this vulnerability:

1. Microsoft Malware Protection Engine Vulnerability- CVE-2008-1437

2. Microsoft Malware Protection Engine Vulnerability- CVE-2008-1438

(For those who do not know, the CVE is sponsored by the National Cyber Security Division of the U.S. Department of Homeland Security and they track all reported vulnerabilities.)

The first one is pretty odd and just annoying. The vulnerability causes their software engine to “hang and reboot“. And that’s different from any other Microsoft program because?????

The second CVE report is what’s fascinating to me and interesting the way M$ plays it down in the initial bulletin.

CVE reports:

…allows context-dependent attackers to cause a denial of service (disk space exhaustion) via a file with “crafted data structures” that trigger the creation of large temporary files, a different vulnerability than CVE-2008-1437.

To translate that into common, every day language, the vulnerability allows an attacker to use a specially crafted file (crafted data structures) that when the Microsoft product scans the file for malicious content, it causes you to use up all your disk space (disk space exhaustion) by creating large temporary files on your computer which results in your not being able to use your computer (denial of service).

I vaguely remember an old virus that used to do that!

The updated fix is available, but that’s not the point. (Although if you’re running this garbage, you should update immediately!)

The point is Microsoft has been selling you a line of marketing bull sh**!

Here’s their sales pitches directly from their website:

Anyone else see a problem with this besides me? (HINT: I’ve bolded all the products they’re wanting you to use for your security that were affected by this vulnerability!) I’m going to trust a company who has never put security first since day one and can’t even build a secure product designed to be secure to protect me???

Oh, and in case you don’t want to go read what caused this vulnerability in the first place, here’s the actual cause described by Microsoft in the bulletin – under the plus signs of course!

CVE-1437 portion of the vulnerability: The Microsoft Malware Protection Engine does not properly validate input when parsing specially crafted files.

CVE-1438 portion of the vulnerability: The Microsoft Malware Protection Engine does not properly validate certain data structures when parsing files.

Now let me see….. security means, in part, authentication and validation of data, access, and execution of files. And it seems that Microsoft managed to botch the major portion of that basic programming again!

So, I reitterate: Using Microsoft and security in the same sentence is an oxymoron.

Yeah, I think I’ll trust them with my security! NOT!
