Summary
Remote code execution vulnerability in the ChakraCore scripting engine. An attacker can exploit this flaw to execute arbitrary code in the context of the current user, potentially leading to system compromise if the user has administrative rights.
Risk Assessment
Risk of system compromise, malware installation, data theft, or creation of new accounts with full user rights.
Recommendation
Install the security update that modifies how ChakraCore handles objects in memory.
Original NVD description (English source)
A remote code execution vulnerability exists in the way that the ChakraCore scripting engine handles objects in memory. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. The security update addresses the vulnerability by modifying how the ChakraCore scripting engine handles objects in memory.
