"The installed version of Microsoft Exchange / Windows SMTP Service
is affected by at least one vulnerability :

  - Incorrect parsing of DNS Mail Exchanger (MX) resource
    records could cause the Windows Simple Mail Transfer
    Protocol (SMTP) component to stop responding until
    the service is restarted. (CVE-2010-0024)

  - Improper allocation of memory for interpreting SMTP
    command responses may allow an attacker to read random
    email message fragments stored on the affected server.
    (CVE-2010-0025)

  - Predictable transaction IDs are used, which could allow
    a man-in-the-middle attacker to spoof DNS responses.
    (CVE-2010-1689)

  - There is no verification that the transaction ID of a
    response matches the transaction ID of a query, which
    could allow a man-in-the-middle attacker to spoof DNS
    responses. (CVE-2010-1690)"
