The Microsoft Office Compatibility Products are missing a security update. It is, therefore, affected by the following vulnerability :

  - 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. 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-2018-8577)

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 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-2018-8577)

  - 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-2018-8539)

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 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-2018-8577)

  - 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-2018-8539)

  - An information disclosure vulnerability exists when     Microsoft SharePoint Server improperly discloses its     folder structure when rendering specific web pages. An     attacker who took advantage of this information     disclosure could view the folder path of scripts loaded     on the page. To take advantage of the vulnerability, an     attacker would require access to the specific SharePoint     page affected by this vulnerability. The security update     addresses the vulnerability by correcting how scripts     are referenced on some SharePoint pages. (CVE-2018-8578)

  - 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-2018-8568,     CVE-2018-8572)

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 vulnerability:

  - 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. 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.

  Exploitation of the vulnerability requires that a user open a   specially crafted file with an affected version of Microsoft Excel.
  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)   containing a specially crafted file designed to exploit the   vulnerability. An attacker would have no way to force users to visit   the website. Instead, an attacker would have to convince users to   click a link, typically by way of an enticement in an email or   instant message, and then convince them to open the specially   crafted file. The security update addresses the vulnerability by   correcting how Microsoft Excel handles objects in memory   (CVE-2018-8574, CVE-2018-8577)
