SynopsisThe Microsoft Office Products are affected by multiple vulnerabilities.
DescriptionThe Microsoft Office Products are missing security updates.
It is, therefore, affected by multiple vulnerabilities :
- A remote code execution vulnerability exists when the Windows Jet Database 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 Windows Jet Database Engine handles objects in memory. (CVE-2019-1246)
- 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-2019-1297)
- 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-2019-1263)
- A security feature bypass vulnerability exists when Microsoft Office improperly handles input. An attacker who successfully exploited the vulnerability could execute arbitrary commands. In a file-sharing attack scenario, an attacker could provide a specially crafted document file designed to exploit the vulnerability, and then convince a user to open the document file and interact with the document by clicking a specific cell.
The update addresses the vulnerability by correcting how Microsoft Office handles input. (CVE-2019-1264)
SolutionMicrosoft has released the following security updates to address this issue:
-KB4475591 For Office 365, Office 2016 C2R, or Office 2019, ensure automatic updates are enabled or open any office app and manually perform an update.
