CVE-2017-8609

Status: ModifiedHigh (7.5)—

Microsoft Internet Explorer in Microsoft Windows 10 Gold, 1511, 1607, and 1703, and Windows Server 2016 allow an attacker to execute arbitrary code in the context of the current user when the JavaScript engine fails to render when handling objects in memory in Microsoft Internet Explorer, aka "Scripting Engine Memory Corruption Vulnerability". This CVE ID is unique from CVE-2017-8596, CVE-2017-8610, CVE-2017-8618, CVE-2017-8619, CVE-2017-8595, CVE-2017-8601, CVE-2017-8603, CVE-2017-8604, CVE-2017-8605, CVE-2017-8606, CVE-2017-8607, CVE-2017-8608, and CVE-2017-8609.
