NASL family MacOS X Local Security Checks NASL id MACOS_MS18_JAN_OFFICE.NASL description 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.
