An attacker who successfully     exploited the vulnerability could view out of bound     memory. Exploitation of the vulnerability requires that     a user open a specially crafted file with an affected     version of Microsoft Office software. The security     update addresses the vulnerability by properly     initializing the affected variable. (CVE-2018-8378)

The Microsoft Office Viewer / Office Compatibility 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 information disclosure vulnerability exists when     Microsoft Office software reads out of bound memory due     to an uninitialized variable, which could disclose the     contents of memory. An attacker who successfully     exploited the vulnerability could view out of bound     memory. Exploitation of the vulnerability requires that     a user open a specially crafted file with an affected     version of Microsoft Office software. The security     update addresses the vulnerability by properly     initializing the affected variable. (CVE-2018-8378)
