Buffer Overflow
The Mercur Mailserver is a small Mail Transfer Agent (MTA). It has been reported that there is a buffer overflow in the IMAP AUTH command. The issue occurs when an overly long command is submitted. This could lead to privileged access to the vulnerable system.
This vulnerability has been resolved in version 4.2 Service Pack 3a. See referenced vendor advisory for additional details.
