      MSN Messenger Authentication DoS
    ------------------------------------------------------------------------

    SUMMARY

    " <http://messenger.msn.com/> Microsoft's MSN Messenger is an instant
    messaging client for Windows and Mac, based machines, based on the
    Passport system."

    MSN Messenger does not validate user authentication when account logon
    fails, allowing attackers to cause the account of the victims to become
    temporarily suspended.

    DETAILS

    Any person can try to brute force a victim's MSN messenger password, until
    MSN temporarily suspends the account. While the account is temporarily
    suspended, not even the real owner of the MSN Messenger Passport account
    can login (even if the correct password is used).
