Microsoft Word 2016 in Microsoft Office 2016 allows a remote code execution vulnerability due to the way objects are handled in memory, aka "Microsoft Word Remote Code Execution Vulnerability". This CVE is unique from CVE-2018-0794.

The Microsoft Office 2016 application installed on the remote macOS or Mac OS X host is missing a security update. It is, therefore, affected by the following vulnerabilities:

  - A remote code execution vulnerability exists in Microsoft Office     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. Users whose accounts     are configured to have fewer user rights on the system could be     less impacted than users who operate with administrative user     rights. (CVE-2018-0792)

  - A remote code execution vulnerability exists in the way that     Microsoft Outlook parses specially crafted email messages. An     attacker who successfully exploited the vulnerability could take     control of an affected system. An attacker could then install     programs; view, change, or delete data; or create new accounts     with full user rights. (CVE-2018-0793)

  - A remote code execution vulnerability exists in Microsoft Office     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. Users whose accounts     are configured to have fewer user rights on the system could be     less impacted than users who operate with administrative user     rights. (CVE-2018-0794)

  - A spoofing vulnerability exists when Microsoft Outlook for MAC     does not properly handle the encoding and display of email     addresses. This improper handling and display may cause antivirus     or antispam scanning to not work as intended. (CVE-2018-0819)

The Microsoft Words Products are missing security updates. It is therefore affected by multiple issues involving handling of Office and RTF (Rich Text Format) files. If successfully exploited, an attacker could execute code in the context of the current user.

The Microsoft Office Online Server or Microsoft Office Web Apps installation on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities :

  - An Office RTF remote code execution vulnerability exists     in Microsoft Office software when the Office software     fails to properly handle RTF files. 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-2018-0797)

  - A remote code execution vulnerability exists in     Microsoft Office 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-2018-0792)

The Microsoft SharePoint Server or Microsoft Project Server installation on the remote host is missing security updates. It is, therefore, affected by the following vulnerabilities :

  - An elevation of privilege vulnerability exists when Microsoft     SharePoint Server does not properly sanitize a specially crafted     web request to an affected SharePoint server. An authenticated     attacker could exploit the vulnerability by sending a specially     crafted request to an affected SharePoint server.
    (CVE-2018-0789, CVE-2018-0790)

  - A remote code execution vulnerability exists in Microsoft Office     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. Users whose accounts     are configured to have fewer user rights on the system could be     less impacted than users who operate with administrative user     rights. (CVE-2018-0792)

  - An Office RTF remote code execution vulnerability exists in     Microsoft Office software when the Office software fails to     properly handle RTF files. 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. Users     whose accounts are configured to have fewer user rights on the     system could be less impacted than users who operate with     administrative user rights. (CVE-2018-0797)

  - A cross-site-scripting (XSS) vulnerability exists when Microsoft     Access does not properly sanitize inputs to image fields edited     within Design view. An attacker could exploit the vulnerability by     sending a specially crafted file to a victim, or by hosting the     file on a web server. (CVE-2018-0799)
