Take your time, get it right for March Patch Tuesday

March 17, 2020 admin Microsoft Office, PCs, Security, windows

This is a big update to the Windows platform for the Microsoft March Patch Tuesday release cycle. Consisting of 115 patches, mostly to the Windows desktop, with almost all of the critical issues relating to browser-based scripting engine memory issues, this will be a difficult set of updates to release and manage.

The testing profile for the Windows desktop platform is very large, with a lower than usual exploitability/risk rating. For this month, we do not have any reports of publicly exploited or disclosed vulnerabilities (zero-days), so my recommendation is to take your time, test the changes to each platform, create a staged rollout plan and wait for future (potentially) imminent changes from Microsoft.

Microsoft Patch Alert: February 2020 patches bring fire and ice but seem to have settled – finally.

The real stinker this month, KB 4524244, rolled out the automatic update chute for four full days until Microsoft yanked it – leaving a trail of wounded PCs, primarily HP machines, in its wake. The other big-time bug in this month’s patches, a race condition in the KB 4532693 Win10 version 1903 and 1909 cumulative update installer, hasn’t been officially acknowledged by Microsoft outside of a blog post. But at least it’s well known and understood.

Folks running SQL Server and Exchange Server networks need to get patched right away.

Win10 UEFI update KB 4524244 blockages

Patch Tuesday brought KB 4524244 for Windows 10 owners, a bizarre single-purpose patch apparently directed at one specific UEFI bootloader. I talked about it last week.

Microsoft springs last-minute demand on buyers of Windows 7 after-expiration support

Microsoft this week threw a wrench into the workings of its long-touted Windows 7 post-retirement support, telling IT administrators that there was a brand new prerequisite that must be installed before they can download the patches they’d already paid for.

The last-minute requirement was titled “Extended Security Updates Licensing Preparation Package” and identified as KB4538483 in Microsoft’s numerical format.

The licensing prep package can be downloaded manually from the Microsoft Update Catalog. It should also appear in WSUS (Windows Server Update Services), the patch management platform used by many commercial customers. It will not, however, be automatically delivered through the Windows Update service, which some very small businesses rely on to provide them necessary patches.

A large – but manageable – February Patch Tuesday brings critical browser updates

February 13, 2020 admin PCs, Security, windows

With 99 reported vulnerabilities and patches to both Microsoft browsers, Office and Windows, this month’s Patch Tuesday update is not as large an administrative burden as you might initially think. We’ve rated the browser updates as a “Patch Now” update due to issues with the Chakra engine, but both Office and Windows can be scheduled according to a regular patch cadence. Unfortunately, we have another Adobe Flash update to deploy, but no critical development updates for February.

Patch Tuesday: 99 holes, 'exploited' IE fix, Win7 mayhem and UEFI ghost

February 12, 2020 admin PCs, Security, windows

What a month it’s been – and the Patch Tuesday patches have only been out for 24 hours. There are many February patching foibles to report.

Every version of Windows 10, stretching back to the beginning of time (except for the long-neglected version 1511) got patches this month.

Welcome to the new, improved, paid-for Win7 patches

There was no free Windows 7 update this month, even though Microsoft released a Monthly Rollup Preview in January. Anyone concerned about the well-documented “Stretch” black wallpaper bug caused by last month’s Win7 Monthly Rollup apparently can pound sand – or manually download and install the fix. Your choice.

The perils of shouting 'fire' in a crowd of PC patchers

Time and again we see the same drama play out. Microsoft releases a security patch and scary warnings appear from every corner. When your local news broadcast tells you that you better patch Windows right now…, more temperate advice should prevail.

A little over two weeks ago, on Patch Tuesday, Microsoft released a patch for a security hole known as CVE-2020-0601 – the Crypt32.dll vulnerability also called ChainOfFools or CurveBall.

Microsoft Patch Alert: January 2020 patches look relatively benign

January 23, 2020 admin microsoft, Microsoft Office, PCs, Security, windows

Credit to Author: Woody Leonhard| Date: Thu, 23 Jan 2020 07:17:00 -0800

The big patching problems this month fell at the feet of admins who had to deal with an unholy mess of pressing exposures: Fixing the holes in Microsoft’s RD Gateway (CVE-2020-0610; see Susan Bradley’s Patch Watch, paywalled); dealing with Server 2008 R2 systems that booted to Recovery mode after installing the January patches; scrambling to pick up after breaches in Citrix networking products; or the 334 Oracle security patches. They all took a toll.
