Patching computers increases vulnerability?

[pne]

Someone pointed out this quote to me from [1]:

In einem internen Testlauf stellten wir fest, dass das Exploit auf einem Windows XP mit IE 6.0 erst lauffähig war, nachdem wir alle aktuellen Sicherheitspatches von windowsupdate.com eingespielt hatten

or in English:

In an internal test we found that the exploit would only run on a Windows XP system with IE 6.0 after we had installed all current security patches from windowsupdate.com.

well, think about all the times a bug was introduced on LJ while patching another one? the other week, a bug i reported was fixed in a way that didn't allow non supporthelps to submit screened answers. that was fixed quickly, but it happens.
