Is this a new zero-day denial-of-service attack or a new CVE being exploited? Dovecot suddenly started acting really strangely on my system lately. PAM authentication started failing randomly, so I reconfigured for shadow authentication instead, which works now, but messages I have received from other domains since about 11:00 am AKST today are "invisible" and not being synced in my inbox for some reason.

Something is really, really bad is going on.

Does this mean I have some problems with filesystem uid's? Currently I have only u=rwx, go is nothing.
