CVE-2017-11791

LOW 3.1EPSS 5.49%

Does this matter?

Lower severity and a low EPSS score (5.49%). Track it; it rarely justifies an emergency change on its own.

Description

ChakraCore and Internet Explorer in Microsoft Windows 7 SP1, Windows Server 2008 SP2 and R2 SP1, Windows 8.1 and Windows RT 8.1, Windows Server 2012 and R2, and Microsoft Edge and Internet Explorer in Windows 10 Gold, 1511, 1607, 1703, 1709, Windows Server 2016 and Windows Server, version 1709 allows an attacker to obtain information to further compromise the user's system, due to how the scripting engine handles objects in memory, aka "Scripting Engine Information Disclosure Vulnerability". This CVE ID is unique from CVE-2017-11834.
