Hi tfichtner,
You are absolutely right, it should apply only to windows 8.1 and 8 according to the article http://support.microsoft.com/en-us/kb/3025417
I double checked the affected platform and windows 2012 is among which is an mistake from our patch content team.
No bug have been so far filed up yet according to our system, then please open right away a case with support and provide the information with the MS link I provided you,
Hopefully, it answered to your question,
Good luck!
