<div class="IPBDescription">You need to read this!</div> This doesn't really belong in general but it's a MAJOR problem and a lot of NS people are being hit by it so the message needs to reach as many as possible!

---

This isn't very new (About a month old) but recently it seems worms have been written to use exploit this and it's been happening to a lot of people, so if you haven't installed this patch or have been getting strange crashes you need this!

This does not effect 95/95/ME because they are not based on NT.

Firewalls will help against this exploit but it would be a good idea to install this patch anyway.

Critical security rating for the following Windows Versions:

What?s the scope of the vulnerability?

This is a buffer overrun vulnerability. An attacker who successfully exploited this vulnerability could gain complete control over a remote computer. This would give the attacker the ability to take any action on the server that they want. For example, and attacker could change Web pages, reformat the hard disk, or add new users to the local administrators group.

Who could exploit the vulnerability?

Any user who could deliver a TCP request to an RPC interface to an affected computer could attempt to exploit the vulnerability. Because RPC requests are on by default in all versions of Windows, this in essence means that any user who could establish a connection with an affected computer could attempt to exploit the vulnerability. <!--QuoteEnd--></td></tr></table><span class='postcolor'><!--QuoteEEnd-->

For anyone having problems getting the patch (Thanks NEWSBOT3):

1. Stop the problem from shutting you down, so you can fix it.
press Start-run, type 'dcomcnfg' (without the quotes) and press enter
Now goto Component Services, and double-click Computers.
Right-click My Computer and select properties. Goto the Default Properties tab, and DESELECT Enable Distributed COM on this computer
Press Apply, then ok, and close Component services.

2. THIS IS VERY IMPORTANT TO DO
Now, reboot your machine. If you do not do this, someone can still have access to your machine, and can be causing more damage etc.

3. Goto the MS site, and get the patch for this problem.

WinXP users should choose the '32 bit' option

4. Install patch

5. THIS IS VERY IMPORTANT TO DO
Reboot your machine for the final time.

At this stage you can re-visit step 1 and re-enable Enable Distributed COM on this computer , its fine to do this as long as you have followed all the steps above.

6. THIS IS EXTREMELY IMPORTANT TO DO
Virus scan your machine. Since potentially, someone could have had complete control of your pc, you need to be sure its clean.

    <a href='http://www.grc.com' target='_blank'>www.grc.com</a> Has more information
    <a href='https://grc.com/x/portprobe=135' target='_blank'>Click this link</a> to see if you are vulnerable.
    If the above link says "Closed" or "Stealth" You are not vulnerable, if it says "Open!" you are.

    Of course, using the free software firewall <a href='http://www.zonelabs.com/store/content/company/products/znalm/freeDownload.jsp' target='_blank'>Zonealarm</a> causes any attempt to connect to my computer blocked and logged. It also prevents software from accessing the internet without your permission. It also closes the affected port, makeing me protected before it was detected
    Lets look at what Zonealarm blocked on my computer: 13889, yes 13889 attempts at connecting to my computer by anyone on the internet, who wasnt supposed to. Out of those, 7852 have been high-rated. Not all of those are bad, but many are. Even more are people scanning the internet, looking for unsecured machines.. Is yours one of these unsecured machines?

    I personally will be getting the GRC patch as opposed to the MS patch

    See <a href='http://grc.com/default.htm' target='_blank'>http://grc.com/default.htm</a> for more information about this, Messenger annoyances, and various other security resources, including a web based port scanner (it can only scan your computer) and information about closing the netbios port.

    I'm going to guess that my router is probably going to make it impossible for them to gain control. But I've recently updated windows anyways.

    Thanks for the heads up though Commando.

    I don't know how you managed to get spyware from the official Microsoft page but try Spybot to remove it.

    Or for that matter, why we still use languages which don't have built in concept of string length... <i>/me ducks</i>

    Does the online virus scanner remove the viruses? Because it picked up a trojan and I couldn't find the file, was wondering if it removed it :|

    Yes, it seems this exploit popped up over the weekend. It hit two of my business computers and restarted them every couple hours. You can also stop this exploit by editing your registry. One of my friends figured out how to do it so I will have to talk to him to see exactly what he did.

    Use the test I had above, to check if its good, if not:
    Open zonealarm
    Click Firewall
    Move the slider in internet to high

    Repeat test
