Changelog of KB4343897 Update
- Provides protection against a new speculative execution side-channel vulnerability known as L1 Terminal Fault (L1TF) that affects Intel® Core® processors and Intel® Xeon® processors (CVE-2018-3620 and CVE-2018-3646). Make sure previous OS protections against Spectre Variant 2 and Meltdown vulnerabilities are enabled using the registry settings outlined in the Windows Client and Windows Server guidance KB articles. (These registry settings are enabled by default for Windows Client OS editions, but disabled by default for Windows Server OS editions.)
- Addresses an issue that causes high CPU usage that results in performance degradation on some systems with Family 15h and 16h AMD processors. This issue occurs after installing the June 2018 or July 2018 Windows updates from Microsoft and the AMD microcode updates that address Spectre Variant 2 (CVE-2017-5715 – Branch Target Injection).
- Updates support for the draft version of the Token Binding protocol v0.16.
- Addresses an issue that causes Device Guard to block some ieframe.dll class IDs after the May 2018 Cumulative Update is installed.
- Ensures that Internet Explorer and Microsoft Edge support the preload=”none” tag.
- Addresses an issue that displays “AzureAD” as the default domain on the sign-in screen after installing the July 24, 2018 update on a Hybrid Azure AD-joined machine. As a result, users may fail to sign in in Hybrid Azure AD-joined scenarios when users provide only their username and password.
- Addresses an issue that adds additional spaces to content that’s copied from Internet Explorer to other apps.
- Addresses a vulnerability related to the Export-Modulemember() function when used with a wildcard (*) and a dot-sourcing script. After installing this update, existing modules on devices that have Device Guard enabled will intentionally fail. The exception error is “This module uses the dot-source operator while exporting functions using wildcard characters, and this is disallowed when the system is under application verification enforcement”. For more information, see https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2018-8200 and https://aka.ms/PSModuleFunctionExport.
- Addresses an issue that was introduced in the July 2018 .NET Framework update. Applications that rely on COM components were failing to load or run correctly because of “access denied,” “class not registered,” or “internal failure occurred for unknown reasons” errors.
- Addresses a vulnerability issue by correcting the way that the .NET Framework handles high-load or high-density network connections. For more information, see CVE-2018-8360.
- Security updates to Windows Server.
