A remote code execution issue exists in the Equation Editor of Microsoft Office and WordPad due to improper memory object handling, leading to a buffer overflow. An attacker can exploit this by inducing a user to open a specially crafted file, allowing the execution of arbitrary code within the context of the current user. If the user possesses administrative privileges, the attacker could gain full control of the system, enabling them to install software, modify or delete data, and create new accounts with full user rights. This issue has been exploited by multiple Chinese threat groups since late 2018.
