"An unchecked buffer condition could allow an attacker to execute
arbitrary code on the remote host.

To execute this flaw, an attacker would need to send a malformed message

Exchange is installed) or by sending an email to a user on the remote
host.

When the email is processed by CDO, an unchecked buffer may allow cause
code execution.");
