Name of the Vulnerable Software and Affected Versions Microsoft Edge (affected versions not specified)

Description The issue is caused by a buffer overflow in the JavaScript engine of the Microsoft Edge browser, leading to memory corruption when handling objects. This could allow a remote attacker to execute arbitrary code in the context of the current user by displaying specially crafted content. If the current user has administrative rights, a successful exploitation could grant the attacker control over the affected system, enabling them to install programs, view, change, or delete data, or create new accounts with full user rights.
