"The Microsoft Excel Products are missing security updates. They are,
therefore, affected by multiple vulnerabilities :

  - An information disclosure vulnerability exists when Microsoft
    Excel improperly discloses the contents of its memory. An
    attacker who exploited the vulnerability could use the
    information to compromise the user's computer or data. To exploit
    the vulnerability, an attacker could craft a special document
    file and then convince the user to open it. An attacker must know
    the memory address location where the object was created.
