Critical Information about the SharePoint Server 2010 October 2010 Cumulative Update

From the SharePoint Team Blog:

Microsoft has discovered a critical issue in the recently released October Cumulative Updates for SharePoint Server 2010 and Project Server 2010, and we have removed the files from download availability.  If you have already downloaded the CU, do not install it. If you have installed the CU, please contact Microsoft Support for assistance.  We will be posting additional information about the issue here as soon as we have it, and will make the Cumulative Update available for download again as soon as the issue has been fully resolved.

Pretty simple. DO NOT install it! If you already have, get in touch with CSS as soon as possible, and keep an eye on the Team blog for further updates in the near future.

[UPDATE] the details of the workaround have been posted here.
