IMail Server contains a flaw that may allow a remote denial of service. The issue is due to the IMAP daemon (IMAPD32.EXE) service while parsing malformed LSUB commands. By passing an overly long string of NULL characters to the 'LSUB' command, a remote attacker can cause the daemon to go into an infinite loop and consume all available CPU resources resulting in a loss of availability for the IMAP service.
