Description

Microsoft Edge in Microsoft Windows 10 1511, 1607, 1703, and Windows Server 2016 allows an attacker to execute arbitrary code in the context of the current user, due to the way that Microsoft browser JavaScript engines render content when handling objects in memory, aka "Scripting Engine Memory Corruption Vulnerability".
