Well, this one was patched (or more accurately, undone).  Perhaps.  Maybe. 

How many other "paid defects" do you estimate there are in Microsoft Windows waiting to be exploited when discovered 
(or disclosed) by someone other than the "Security Agency" buying the defect?

Almost certainly more than just this one ... and almost certainly there is more than a single "payor agency" 
independently purchasing the deliberate introduction of code defects.

Well it was patched by Microsoft of March 14th, just clearly people
running large amounts of probably Windows XP have been owned.

Largely in Russia.

The SMBv1 issue was disclosed a year or two ago and never patched.
Anyone who was paying attention would already have disabled SMBv1.

Thus is the danger and utter stupidity of "overloading" the function of
service listeners with unassociated road-apples.  Wait until the bad guys
figure out that you can access the same "services" via a connection to the
DNS port (UDP and TCP 53) on windows machines ...

(workstations?) to disable SMBv1 entirely.

Kaspersky reckons the exploit applies to SMBv2 as well:

I thought it was a typo in para 2 and the table, but they emailed back
saying nope, SMBv2 is (was) also broken. However, they also say (same
page) that the MS patch released in March this year fixes it.

Assuming they are right, I wonder why Microsoft didn't mention SMBv2?
