Per Windows 7, Microsoft ha rilasciato l’aggiornamento KB4284826 con il seguente changelog:

  • Provides support to control use of Indirect Branch Prediction Barrier (IBPB) on some AMD processors (CPUs) for mitigating CVE-2017-5715, Spectre Variant 2 when switching from user context to kernel context. (See AMD Architecture Guidelines for Indirect Branch Control and AMD Security Updatesfor more details). For Windows client (IT pro) guidance, follow the instructions in KB4073119. For Windows Server guidance, follow the instructions in KB4072698. Use these guidance documents to enable use of IBPB on some AMD processors (CPUs) for mitigating Spectre Variant 2 when switching from user context to kernel context.
  • Provides protections from an additional subclass of speculative execution side channel vulnerability known as Speculative Store Bypass (CVE-2018-3639). These protections aren’t enabled by default. For Windows client (IT pro) guidance, follow the instructions in KB4073119. For Windows Server guidance, follow the instructions in KB4072698. Use this guidance document to enable mitigations for Speculative Store Bypass (CVE-2018-3639) in addition to the mitigations that have already been released for Spectre Variant 2 (CVE-2017-5715) and Meltdown (CVE-2017-5754).
  • Increased the Internet Explorer cookie limit from 50 to better align with industry standards.
  • Improves the reliability of Internet Explorer when using geolocation.
  • Security updates to Internet Explorer, Windows apps, Windows Server, Windows storage and filesystems, Windows wireless networking, and Windows virtualization and kernel.

Per Windows 8.1, Microsoft ha rilasciato l’aggiornamento KB4284815 con il seguente changelog:

  • Addresses an issue where firmware updates cause devices to go into BitLocker recovery mode when BitLocker is enabled, but Secure Boot is disabled or not present. This update prevents firmware installation on devices in this state. Administrators can install firmware updates by:
    1. Temporarily suspending BitLocker.
    2. Immediately installing firmware updates before the next OS startup.
    3. Immediately restarting the device so that BitLocker doesn’t remain in the suspended state.
  • Permits a band-capable disk that has only one partition, and it is an MSR partition, to convert to a dynamic disk.
  • Increases the Internet Explorer cookie limit from 50 to better align with industry standards.
  • Improves the reliability of Internet Explorer when using geolocation.
  • Security updates to Internet Explorer, Windows apps, remote code execution, Windows Server, Windows storage and filesystems, and Windows wireless networking.
