Is this a new trend? Revealing that there had been a couple of exploitables, backdoors in your s/w when you patch some other ones and then have to roll back because you p.’d off the wrong ones since you accidentally also patched or disabled some hitherto secret ones.
At least, this is what it seems like when reading this; M$ stealthily (apparently not secretly enough) patching some stuff in negative time i.e., before-zero day. When later there’s rumours about this patch(ing, possibly parts of) is retracted.
For this, there appear (again) to be two possible reasons:
a. You flunked the patch and it kills some Important peoples’ system(s);
b. You ‘flunked’ the patch and you did right, but the patch effectively killed some still-not-revealed (in the stash) backdoors that the Important peoples (TLAs) still had some use for and were double-secretly requested to put back in place.
I’m in a Movie Plot mood (come to think of it, for no reason; ed.) and go for the second option. Because reasons (contradictory; ed.). Your 2¢ please.
