  • More Intel microcode updates released through the Update Catalog

    Posted on February 5th, 2019 at 14:37 admin Comment on the AskWoody Lounge

    I count 14 separate updates in the Microsoft Update Catalog, all of which are dated “2019-01” but released on Feb. 4. The main ones:

    Win10 1809 – KB 4465065

    Win10 1803 – KB 4346084

    Win10 1709 – KB 4346085

    and several lesser releases of the same ilk.

    Of course, you shouldn’t install them, unless your company’s mentat predicts a Spectre 3a, 4, or L1TF attack that no one else has seen.

  • Hangover Tuesday: Every version of Windows 10 gets yet another Intel microcode patch

    Posted on August 21st, 2018 at 14:28 woody Comment on the AskWoody Lounge

    There are 13 new August patches in the Microsoft Update Catalog, all dated August 20, all released in the past hour or two.

    They’re Intel microcode updates, e.g., KB 4346084 is for Win10 version 1803.

    Intel recently announced that they have completed their validations and started to release microcode for recent CPU platforms related to Spectre Variant 3a (CVE-2018-3640: “Rogue System Register Read (RSRE)”), Spectre Variant 4 (CVE-2018-3639: “Speculative Store Bypass (SSB)”), L1TF (CVE-2018-3615, CVE-2018-3620, CVE-2018-3646: “L1 Terminal Fault”). In addition to microcode updates previously released in KB4100347​ to address Spectre Variant 2 (CVE 2017-5715: “Branch Target Injection”), this update also includes microcode updates from Intel for the following CPUs.

    Susan Bradley notes that the KB articles were changed recently to say that they’re only available for direct download on the Microsoft Update Catalog. You shouldn’t be getting them through Windows Update. Fingers crossed.

    Of course, we’re at MS-DEFCON 2, so I’d suggest you give them a pass. Nope, there still aren’t any Meltdown or Spectre (Variant n, n=1 to 4) exploits in the wild that you need to be concerned about.

    UPDATE: Crysta notes that there are two more microcode updates, both dated Aug 21, but they appear to be re-issues for last month’s microcode updates. KB 4090007 for Win10 1709 and KB 4100347 for 1803.  jescott418 notes that KB 4100347 is arriving via Windows Update on his Win10 Home 1803 computer.

    ANOTHER UPDATE: I’m not sure WHAT those two re-issued updates cover.
