I am guessing it is a matter of time before the application (Citrix provisioning server) accesses the bad page and freaks out, but will the problem get worse?
Corruption won't spread if that's what you're asking. It's not an infectious disease. That said, depends on the cause. Corruption is typically due to a bad IO subsystem. If it was a once off glitch (power spike or similar) then maybe that's it. If the IO subsystem is misbehaving, then other parts of the DB could be corrupt or become corrupt and without any way to check, you won't know until something important breaks.
Looks like you need to create a new database and start moving data.
