True North eMailServer < 5.3.4 Build 2019 LIST Command Remote DoS (deprecated)



The remote host is vulnerable to a Denial of Service (DoS) attack.


The remote host is running the True North eMailServer. This version of eMailServer is vulnerable to a content-parsing flaw where a malformed IMAP request can cause the server to fail. An attacker exploiting this flaw would be able to disable the service remotely.


Upgrade to version 5.3.4 Build 2019 or higher.
