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

  - A remote code execution vulnerability exists in     Microsoft Word software when it fails to properly handle     objects in memory. An attacker who successfully     exploited the vulnerability could use a specially     crafted file to perform actions in the security context     of the current user. For example, the file could then     take actions on behalf of the logged-on user with the     same permissions as the current user.  (CVE-2019-0585)

  - An information disclosure vulnerability exists when     Microsoft Word macro buttons are used improperly. An     attacker who successfully exploited this vulnerability     could read arbitrary files from a targeted system.
    (CVE-2019-0561)

The Microsoft Office Products are missing security updates.
It is, therefore, affected by multiple vulnerabilities:

  - A remote code execution vulnerability exists in the way     that the MSHTML engine improperly validates input. An     attacker could execute arbitrary code in the context of     the current user. (CVE-2019-0541)

  - An information disclosure vulnerability exists when     Microsoft Outlook improperly handles certain types of     messages. An attacker who successfully exploited this     vulnerability could gather information about the victim.
    An attacker could exploit this vulnerability by sending     a specially crafted email to the victim. The update     addresses the vulnerability by correcting the way     Microsoft Outlook handles these types of messages.
    (CVE-2019-0559)

  - An information disclosure vulnerability exists when     Microsoft Office 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-2019-0560)

  - An information disclosure vulnerability exists when     Microsoft Office 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-2019-0560)

  - A remote code execution vulnerability exists in     Microsoft Word software when it fails to properly handle     objects in memory. An attacker who successfully     exploited the vulnerability could use a specially     crafted file to perform actions in the security context     of the current user. For example, the file could then     take actions on behalf of the logged-on user with the     same permissions as the current user. (CVE-2019-0585)

The Microsoft Sharepoint Server installation on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities :

  - A remote code execution vulnerability exists in     Microsoft Word software when it fails to properly handle     objects in memory. An attacker who successfully     exploited the vulnerability could use a specially     crafted file to perform actions in the security context     of the current user. For example, the file could then     take actions on behalf of the logged-on user with the     same permissions as the current user.  (CVE-2019-0585)

  - An information disclosure vulnerability exists when     Microsoft Word macro buttons are used improperly. An     attacker who successfully exploited this vulnerability     could read arbitrary files from a targeted system.
    (CVE-2019-0561)

  - A cross-site-scripting (XSS) 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. The attacker who     successfully exploited the vulnerability could then     perform cross-site scripting attacks on affected systems     and run script in the security context of the current     user. The attacks could allow the attacker to read     content that the attacker is not authorized to read, use     the victim's identity to take actions on the SharePoint     site on behalf of the user, such as change permissions     and delete content, and inject malicious content in the     browser of the user. The security update addresses the     vulnerability by helping to ensure that SharePoint     Server properly sanitizes web requests. (CVE-2019-0556,     CVE-2019-0557, CVE-2019-0558)

  - 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. The attacker who     successfully exploited the vulnerability could then     perform cross-site scripting attacks on affected systems     and run script in the security context of the current     user. These attacks could allow the attacker to read     content that the attacker is not authorized to read, use     the victim's identity to take actions on the SharePoint     site on behalf of the user, such as change permissions     and delete content, and inject malicious content in the     browser of the user. The security update addresses the     vulnerability by helping to ensure that SharePoint     Server properly sanitizes web requests. (CVE-2019-0562)

The Microsoft Word Products are missing security updates. It is, therefore, affected by multiple vulnerabilities :

  - A remote code execution vulnerability exists in     Microsoft Word software when it fails to properly handle     objects in memory. An attacker who successfully     exploited the vulnerability could use a specially     crafted file to perform actions in the security context     of the current user. For example, the file could then     take actions on behalf of the logged-on user with the     same permissions as the current user.  (CVE-2019-0585)

  - An information disclosure vulnerability exists when     Microsoft Word macro buttons are used improperly. An     attacker who successfully exploited this vulnerability     could read arbitrary files from a targeted system.
    (CVE-2019-0561)

The Microsoft Office 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 Word     software when it fails to properly handle objects in memory. An     attacker who successfully exploited the vulnerability could use a     specially crafted file to perform actions in the security context     of the current user. For example, the file could then take actions     on behalf of the logged-on user with the same permissions as the     current user.

    To exploit the vulnerability, a user must open a specially crafted     file with an affected version of Microsoft Word software. In an     email attack scenario, an attacker could exploit the vulnerability     by sending the specially crafted file to the user and convincing     the user to open the file. In a web-based attack scenario, an     attacker could host a website (or leverage a compromised website     that accepts or hosts user-provided content) that contains a     specially crafted file that is designed to exploit the     vulnerability. However, an attacker would have no way to force the     user to visit the website. Instead, an attacker would have to     convince the user to click a link, typically by way of an     enticement in an email or Instant Messenger message, and then     convince the user to open the specially crafted file.

    The security update addresses the vulnerability by correcting how     Microsoft Word handles files in memory. (CVE-2019-0585)

  - An information disclosure vulnerability exists when Microsoft Word     macro buttons are used improperly. An attacker who successfully     exploited this vulnerability could read arbitrary files from a     targeted system. To exploit the vulnerability, an attacker could     craft a special document file and convince the user to open it.
    An attacker must know the file location whose data they wish to     exfiltrate. The update addresses the vulnerability by changing the     way certain Word functions handle security warnings.
