The remote host is running Ipswitch Collaboration Suite or IMail Server, commercial messaging and collaboration suites for Windows.
The version of Ipswitch Collaboration Suite / IMail server installed on the remote host contains an IMAP server that suffers from a denial of service flaw. Using a specially crafted LIST command of around 8000 bytes, an authenticated attacker can crash the IMAP server on the affected host, thereby denying service to legitimate users.
