I'd advise caution in rolling Patch 1 out. It is definitely buggy.
One of our boxes loses network connectivity with 8.7i Patch 1 installed after it has been running for a few hours - a reboot brings it back.
But it would be nice to know why McAfee pulled it. A few lines of explanation on the support portal replacing the box exhorting us all to apply it immediately would have been appropriate.
McAfee, the lack of explanation sucks, as does the product
