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 ChakraCore JavaScript engine's memory operation. This could allow a remote attacker to execute arbitrary code in the context of the current user by using a specially crafted web page. The vulnerability can corrupt memory, enabling an attacker to gain the same user rights as 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 At the moment, there is no information about a newer version that contains a fix for this vulnerability.
