Overview

Multiple remote code execution vulnerabilities are reported in Microsoft Word when handling malicious Office and Rich Text Format RTF files. An attacker can exploit these issues by tricking an unsuspecting victim into opening a malicious file. A successful exploit will result in the execution of arbitrary code in the context of the currently logged-in user.
