Fetchmail dereferences NULL after SMTP server not accepting his warning mail to postmaster. Attacker could possibly make fetchmail generate a warning (i.e. by sending too big/malformed mail), but is pretty limited in how could he get the SMTP server refuse a message (maybe fill his mail queue storage by sending lots of mails). All he would get would be to crash the fetchmail. The Red Hat Security Response Team has rated this issue as having low security impact, a future update may address this flaw.
