"The Microsoft Office Products are missing security updates.
It is, therefore, affected by multiple vulnerabilities :
- An information disclosure vulnerability exists in
Microsoft Office software when the software fails to
properly handle objects in memory. An attacker who
successfully exploited this vulnerability could obtain
information to further compromise the users system.
(CVE-2019-1402)
- 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-2019-1448)
- A security feature bypass vulnerability exists in the
way that Office Click-to-Run (C2R) components handle a
specially crafted file, which could lead to a standard
user, any AppContainer sandbox, and Office LPAC
Protected View to escalate privileges to SYSTEM.
(CVE-2019-1449)
- An information disclosure vulnerability exists when
Microsoft Excel improperly discloses the contents of its
memory. An attacker who exploited the vulnerability
could use the information to compromise the users
computer or data. (CVE-2019-1446)");
