-----------------------------------------------------------------------------

Description:

            A buffer overflow exists in the LDAP component of Ipswitch's IMail
            software suite.  Exploitation of this vulnerability allows remote
            execution of arbitrary code with the privileges of the IMail daemon
            (default is SYSTEM).

Details:

            The IMail server ships with several components including an LDAP
            service.  The LDAP server allows a remote client read access to
            the IMail directory.  A vulnerability exists during the authentication
            process which allows an outside attacker remote access to the
            server with the privileges of the SYSTEM account.

            When "binding" to the server with simple authentication a "bind DN"
            and password can be specified.  By providing an overly long string to
            the "bind DN" parameter, it is possible to overwrite the saved return
            address, control the instruction pointer and execute arbitrary code in
            the remote process.

Solution:

            Refer to the advisory published by Ipswitch at

http://www.ipswitch.com/Support/IMail/patch-upgrades.html

            Customers should obtain upgraded software by contacting their customer
            support representative to receive the required patches.
