Title: Alt-N MDaemon Server SMTP HELO Argument Buffer Overflow Vulnerability
Severity: HIGH
Description:
MDaemon is a Microsoft Windows based mail server product.
It has been reported that Alt-N MDaemon server is prone to an SMTP HELO command argument buffer overflow vulnerability.
The issue presents itself likely due to insufficient bounds checking performed when handling malicious SMTP HELO command arguments of excessive length. It has been reported that a remote attacker may exploit this condition to trigger a denial of service in the affected daemon.
Due to the nature of this vulnerability it has been conjectured that it may be possible to leverage the exploitation of this issue to execute arbitrary code in the context of the vulnerable daemon. This however has not been confirmed.
Affected Products:
- Alt-N MDaemon 2.71.0 SP1
