"The Microsoft Office Products are affected by multiple vulnerabilities.");
  script_set_attribute(attribute:"description", value:
"The Microsoft Office Products are missing security updates.
It is, therefore, affected by multiple vulnerabilities :

  - A remote code execution vulnerability exists when the
    Windows Jet Database Engine improperly handles objects
    in memory. An attacker who successfully exploited this
    vulnerability could execute arbitrary code on a victim
    system. An attacker could exploit this vulnerability by
    enticing a victim to open a specially crafted file. The
    update addresses the vulnerability by correcting the way
    the Windows Jet Database Engine handles objects in
    memory. (CVE-2019-1246)

  - A remote code execution vulnerability exists in
    Microsoft Excel software when the software fails to
    properly handle objects in memory. An attacker who
    successfully exploited the vulnerability could run
    arbitrary code in the context of the current user. If
    the current user is logged on with administrative user
    rights, an attacker could take control of the affected
    system. An attacker could then install programs; view,
    change, or delete data; or create new accounts with full
    user rights.  (CVE-2019-1297)

  - 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 users
    computer or data.  (CVE-2019-1263)

  - A security feature bypass vulnerability exists when
    Microsoft Office improperly handles input. An attacker
    who successfully exploited the vulnerability could
    execute arbitrary commands. In a file-sharing attack
    scenario, an attacker could provide a specially crafted
    document file designed to exploit the vulnerability, and
    then convince a user to open the document file and
    interact with the document by clicking a specific cell.
    The update addresses the vulnerability by correcting how
    Microsoft Office handles input. (CVE-2019-1264)");
