Microsoft URL Redirection

It seems like microsoft is having a bad year end to 2008 as the host of security vulnerabilities being published not only in its products but also on their website. The following is one more to the pile of security issues faced by the company these days. Although it is a simple url redirect but the purpose it can be used and is being used is really dangerous mainly because of the domain name itself.

The Url redirection bug would basically redirect users clicking on the unsuspected URL as it has the familiar microsoft dot com domain name. For those of us using NOSCRIPT with firefox normally allow microsoft as the trusted source as it hinders with the browsing of the web contents on thier website.

Let us see how quick Microsoft fixes this vulnerability.

Update: The vulnerability has been patched my Microsoft, the reacted faster then I expected way to go.

MSN Messenger 0day

MSN Messenger 8.x has a rather scary bug that is being exploited by people online.  When any of the strings given below are pasted into the private message box on your MSN Messenger, your Messenger will immediately disconnect.  It happens so quickly that you will think that it has not connected in the first place.

If any of your friends asks you to paste the following in your personal message, do not do this, and if for any reason you have done this then have a look at the temporary workaround mentioned below. Temporary because Microsoft have not yet given a patch for this.

Exploit:

n—a_Á—ay±m—aÁÇáç±Çáß±Çá§ÁaÇáDZOÇá—±Çá§±Çár×ÁÇ á+NÇ áLáÇá

OR

(Error) 'A


Workaround:


There are a couple of workarounds for this bug in case you have been a victim.
First is to delete the following folders from your computer and then sign in

C:\Documents and Settings\Username\Application Data\Microsoft\MSN Messenger
C:\Documents and Settings\Username\Local Settings\Application Data\Microsoft\MSN Messenger
C:\Documents and Settings\Username\Local Settings\Application Data\Microsoft\Windows Live Contacts
C:\Documents and Settings\Username\Contacts\

Second is to login using any web messenger and remove the message in the private message area.

This bug exists only in Windows Live Messenger 8.x so using previous versions will also solve the problem.
