"The version of Microsoft Exchange installed on the remote host has the
following vulnerabilities :

  - Multiple code execution vulnerabilities in the Oracle Outside In
    libraries, used by the WebReady Document Viewing feature of
    Outlook Web App (OWA).  An attacker could exploit this by
    sending a malicious email attachment to a user who views it in
    OWA, resulting in arbitrary code execution as LocalService.
    (CVE-2012-3214, CVE-2012-3217)

  - A denial of service caused by Exchange improperly handling
    RSS feeds.  An attacker with a valid email account on the
    Exchange server could create a specially crafted RSS feed,
    which could cause the system to become unresponsive and
    result in data corruption. (CVE-2012-4791)");
