Checks for buffer overflows in Mercur Mailserver/Messaging IMAP Services
Detailed Explanation for this Vulnerability Assessment
The remote IMAP server is affected by a remote buffer overflow
The remote host is running MERCUR Messaging Server / Mailserver, a
commercial messaging application for Windows.
The IMAP server component of this software fails to properly copy
overly-long arguments to LOGIN and SELECT commands, which can be
exploited to crash the server and possibly to execute arbitrary code
Note that the services run by default with LOCAL SYSTEM rights,
which means that an unauthenticated attacker can potentially gain
complete control of the affected host.
