Description

The Microsoft Office 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 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-2018-8157, CVE-2018-8158, CVE-2018-8161)

- 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)
