The issue is caused by a buffer overflow in Microsoft Office software, including Word Viewer and Microsoft Word, allowing a remote attacker to execute arbitrary code using a specially crafted file. Multiple remote code execution vulnerabilities exist due to the software's failure to properly handle objects in memory. Successful exploitation could allow an attacker to run arbitrary code in the context of the current user, potentially taking control of the affected system if the user has administrative rights. This could enable the attacker to install programs, view, change, or delete data, or create new accounts with full user rights.
