"The Microsoft Office application installed on the remote macOS or Mac
OS X host is missing a security update. It is, therefore, affected by
multiple vulnerabilities :

  - An information disclosure vulnerability exists in the
    Graphics Device Interface (GDI) component due to
    improper handling of objects in memory. A local attacker
    can exploit this, via a specially crafted application,
    to circumvent the Address Space Layout Randomization
    (ASLR) feature and disclose sensitive memory
    information. (CVE-2016-7257)

  - Multiple remote code execution vulnerabilities exist in
    Microsoft Office software due to a failure to properly
    handle objects in memory. An unauthenticated, remote
    attacker can exploit these vulnerabilities by convincing
    a user to open a specially crafted Office file,
    resulting in the execution of arbitrary code in the
    context of the current user. (CVE-2016-7263,
    CVE-2016-7298)

  - Multiple information disclosure vulnerabilities exist in
    Microsoft Office software due to an out-of-bounds memory
    read error. An unauthenticated, remote attacker can
    exploit these vulnerabilities by convincing a user to
    open a specially crafted Office file, resulting in the
    disclosure of memory contents. (CVE-2016-7264,
    CVE-2016-7268, CVE-2016-7276, CVE-2016-7290,
    CVE-2016-7291)

  - An arbitrary command execution vulnerability exists in
    Microsoft Office due to improper validation of registry
    settings when running embedded content. An
    unauthenticated, remote attacker can exploit this by
    convincing a user to open a specially crafted document
    file multiple times, resulting in a bypass of security
    restrictions and the execution of arbitrary commands.
    (CVE-2016-7266)

  - An elevation of privilege vulnerability exists in the
    Microsoft AutoUpdate (MAU) application due to improper
    validation of updates. A local attacker can exploit this
    by placing a specially crafted application in a location
    used by the update application, resulting in the ability
    to execute arbitrary code in a privileged context.
