The security update addresses the vulnerability by correcting how Microsoft Word handles objects in memory. (CVE-2019-1461)

– An information disclosure vulnerability exists in Microsoft Access 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-2019-1400, CVE-2019-1463)

– A remote code execution vulnerability exists in Microsoft PowerPoint 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.
