    descriptionThe Microsoft Office Products are missing security updates. It is, therefore, affected by multiple vulnerabilities : - A remote code execution vulnerability exists when Microsoft Office fails to properly handle certain files. (CVE-2019-0801) - A remote code execution vulnerability exists in the way that Microsoft Graphics Components handle objects in memory. An attacker who successfully exploited the vulnerability could execute arbitrary code on a target system. (CVE-2019-0822) - A remote code execution vulnerability exists when the Microsoft Office Access Connectivity Engine improperly handles objects in memory. An attacker who successfully exploited this vulnerability could execute arbitrary code on a victim system. An attacker could exploit this vulnerability by enticing a victim to open a specially crafted file. The update addresses the vulnerability by correcting the way the Microsoft Office Access Connectivity Engine handles objects in memory. (CVE-2019-0823, CVE-2019-0824, CVE-2019-0825, CVE-2019-0826, CVE-2019-0827) - 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-2019-0828)
