Summary
ChakraCore vulnerable to privilege escalation due to exposure from scriptFunction
Details

ChakraCore and Microsoft Edge in Windows 10 1511, 1607, 1703, 1709, and Windows Server 2016 allows an attacker to gain the same user rights as the current user, due to how the scripting engine handles objects in memory, aka "Scripting Engine Memory Corruption Vulnerability". The JavascriptGeneratorFunction::GetPropertyBuiltIns exposes scriptFunction while trying to get the length property passed the generator function.

This CVE ID is unique from CVE-2017-11886, CVE-2017-11889, CVE-2017-11890, CVE-2017-11893, CVE-2017-11894, CVE-2017-11895, CVE-2017-11901, CVE-2017-11903, CVE-2017-11905, CVE-2017-11905, CVE-2017-11907, CVE-2017-11908, CVE-2017-11909, CVE-2017-11910, CVE-2017-11911, CVE-2017-11912, CVE-2017-11913, CVE-2017-11916, CVE-2017-11918, and CVE-2017-11930.
