Description

Peter Kruse has reported a vulnerability in GFI MailSecurity and GFI MailEssentials, which can be exploited by malicious people to cause a DoS (Denial of Service).

The vulnerability is reportedly caused due to an error in a Microsoft HTML library used by the application for processing HTML emails. This can be exploited to stop the processing of emails by sending a malicious HTML email containing specially crafted JavaScript code.

Manual removal of the malicious email in the mail queue is required to regain normal functionality.


Solution
Apply patches.
