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

Description A remote code execution issue exists in the way JavaScript scripting engines handle objects in memory in Microsoft browsers. This could allow an attacker to corrupt memory and execute arbitrary code in the context of the current user. If the current user has administrative rights, a successful exploitation could lead to an attacker taking control of the affected system, enabling them to install programs, view, change, or delete data, or create new accounts with full user rights.

Recommendations For Microsoft Internet Explorer, update to a version that includes the fix for this issue. For Microsoft Edge, update to a version that includes the fix for this issue. As a temporary workaround, consider restricting the use of JavaScript in these browsers until a patch is available.
