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

Description The issue is caused by a buffer overflow in the JavaScript ChakraCore engine, which can lead to remote code execution. This could allow an attacker to execute arbitrary code in the context of the current user. If the current user has administrative rights, the attacker could take control of the affected system, install programs, view, change, or delete data, or create new accounts with full user rights.

Recommendations For Microsoft Edge, update to a version that includes the fix for this issue. For Internet Explorer, update to a version that includes the fix for this issue. As a temporary workaround, consider restricting access to sensitive data and limiting user privileges to minimize the risk of exploitation.
