I found this in one of the mailing lists I subscribe to:
There is no external KB article at this time, as far as I know. The hotfix readme shows the KB article as http://support.microsoft.com/?kbid=889525, which doesn't exist. The hotfix number is the same -- 889525.
I am running Exchange 2003 SP1, don't know if one is in the works for Exchange 2000.
