MERCUR Mailserver SMTP / IMAP / POP3 Servers Remote Overflows

Critical Nessus Plugin ID 11910


The remote mail server is prone to a buffer overflow attack.


The remote Atrium MERCUR SMTP server (mail server) seems to be vulnerable to a remote buffer overflow. Successful exploitation of this vulnerability would give a remote attacker administrative access to the mail server and access to potentially confidential data.

The IMAP and POP3 servers are affected by similar issues involving the AUTHENTICATE and AUTH commands respectively.


Upgrade to MERCUR Mailserver 4.2 SP3a or later.
