Tenants' rights during foreclosures?

[Vonetta Booker]

A girlfriend of mine called with an issue: The building that she rents an apartment in month-to-month is up for auction next month (it was scheduled for auction on 6/27, but it was cancelled).  She says her landlord refuses to give her any info; she's cautious about paying rent (due tomorrow)--and then being out on the street at a moment's notice. 

What are her rights during a foreclosure? I'm not sure offhand, but I told her I'd ask around & get back to her. :-)  (This is in the state of CT.)
