A remote code execution vulnerability exists in Microsoft Excel software when the software fails to properly handle objects in memory, aka "Microsoft Excel Remote Code Execution Vulnerability." This affects Microsoft Office, Microsoft Excel. This CVE ID is unique from CVE-2018-8148, CVE-2018-8162.

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 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-2018-8147)

  - 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-2018-8162)

  - A remote code execution vulnerability exists in Microsoft     PowerPoint software when the software fails to properly validate     XML content. 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-2018-8176)

The Microsoft Office Compatibility Products are 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-2018-8147, CVE-2018-8148)

  - An information disclosure vulnerability exists in     Outlook when a message is opened. This vulnerability     could potentially result in the disclosure of sensitive     information to a malicious site.  (CVE-2018-8160)

  - A remote code execution vulnerability exists in     Microsoft InfoPath 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-2018-8173)

  - A security feature bypass vulnerability exists when the     Microsoft Outlook attachment block filter does not     properly handle attachments. An attacker who successfully     exploited the vulnerability could execute arbitrary     commands. The security feature bypass by itself does not     allow arbitrary code execution. (CVE-2018-8150)
