Microsoft Office Security Feature Bypass Vulnerability

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.
