Well, if you're really 'affected' you'll likely know it. Upon update we
lost all service to campus. At that point everyone switched to our
wireless infrastructure, which very nearly came down as well. That
proved to be a fun evening... =)

A recently published Cisco NAC rule contained a software defect that
may result in a loss of service for NAC Servers (Clean Access
Servers). Customers with NAC Managers (Clean Access Managers) which
updated their Cisco Updates rulesets between 3:15AM PST 11/11/2008 and
11:15AM PST 11/11/2008 are affected and subsequent updates will not be
downloaded. The affected version of the rule is OS Detection
Fingerprint Version 7.
Note: "OS Detection Fingerprint" is referred to as "OSDF" for the
remainder of this document.
