I installed the out-of-band MS KB 958644 last friday on our CSA management console server (only app on that server), rebooted and was greeted with a BSOD shortly after the server came up.
Tried a couple more times and got same results. Lots of event ID# 333 in the log.
I restored the server to my previous night's backup image and it is running again.
Might try re applying the KB again to see if it happens again.
Specifics are Win2003 RS SP2 with all relevant MS patches / 2 GB RAM / Running on a VMware ESX3i virtual machine. CSA Ver 6.0.201
