Microsoft has eased us into the brand new new 12 months with simply 48 updates for the Home windows, Workplace and .NET platforms. There have been no zero-days for January, and no stories of publicly uncovered vulnerabilities or exploited safety points.
Builders of advanced, line-of-business purposes would possibly must pay specific consideration to how Microsoft has up to date the Message Queue system. Printing has been patched and minor updates to bluetooth and Home windows shell sub-systems (shortcuts and wallpaper) require some testing earlier than deployment.
The workforce at Readiness has crafted a helpful infographic that outlines the dangers related to every of the updates for this January launch.
Recognized points
Every month, Microsoft features a listing of identified points that relate to the working system and platforms included within the newest replace cycle.
- Microsoft reported the next error message for all Home windows 10/11 desktop platforms: Utilizing the FixedDrivesEncryptionType or SystemDrivesEncryptionType coverage settings within the BitLocker configuration service supplier (CSP) node in cellular machine administration (MDM) apps would possibly incorrectly present a 65000 error within the “Require System Encryption” setting for some units in your setting.
Given the significance of emojis in right this moment’s computing setting, Microsoft additionally has a problem with the colour scale of sure 3D-like emoticons on all Home windows builds. (As I’m “coloration dumb,” unsure if I must be 🙂 or 😞.)
Main revisions
So had been there main revisions among the many January updates? There are two solutions. The brief reply is there don’t look like any patches with important revisions that require administrator consideration this month.
The lengthy reply: there might be a problem with the Microsoft replace database and the way knowledge is introduced and deployed. With every replace cycle, the Readiness workforce employs an automatic system to parse/course of Microsoft updates and their related manifests and payloads. Our system reported many modifications, which after a while proved to be false alarms. (By “giant variety of modifications,” we imply a number of thousand.) We double-checked — it isn’t us — it’s the knowledge. We’ll see if the issue persists and replace our methods/bulletins accordingly.
Mitigations and workarounds
Microsoft printed the next vulnerability associated mitigations for this month’s launch:
- CVE-2024-21320: Home windows Themes Spoofing Vulnerability. Microsoft suggested that those that have disabled NTLM will not be affected by this minor situation. If this vulnerability is a priority to your group, apply the Prohibit NTLM group coverage.
Every month, the Readiness workforce detailed analyses the Patch Tuesday updates and offers detailed, actionable testing steerage. This steerage is predicated on assessing a big software portfolio and the patches’ potential affect on the Home windows platforms and software installations.
The next modifications had been included on this month’s replace and haven’t been raised as both elevated danger (of sudden outcomes) and don’t embrace useful modifications:
- Printing has been up to date to forestall a distant code execution state of affairs. Printer redirection processes/configurations will want a check cycle.
- Bluetooth system information have been up to date on all at present supported Home windows desktop builds. I’ve actual hassle with Bluetooth testing as I discover Bluetooth connectivity flaky at finest. This month, check Bluetooth mice, keyboards, and your headsets.
- Base log information (BLF) had been a essential part of ransomware assaults all through 2023 as attackers exploited vulnerabilities within the Home windows Error Reporting and Log file system (WER). These (BLF) file varieties had been up to date this month, and a Home windows Error Log Reporting file check might be required that features file create, learn, replace, and delete operations.
- Core elements of the Microsoft Group Coverage (GPO) administration instruments have been up to date, so GPO templates would require testing by directors and extra importantly, by delegated non-administrators.
- There’s one other replace to how Home windows handles file compression. This time we should always nonetheless count on to check file extraction, with much less deal with file-level compression. We recommend utilizing a command/batch file to run EXTRACT/Extrac32 on at the very least a couple of hundred small to mid-size information.
- You’ll have to embrace a background picture or “Wallpaper” check this month resulting from an replace to Home windows Shell. That is a straightforward one. Can I see my company wallpaper after I login? Sure? Joyful days!
For builders: Microsoft made a significant replace on how Message Queuing (MSMQ) works in Home windows desktops this month. One sub-component of the MSMQ characteristic offers with Distant Process Calls (RPC) generally utilized in distributed purposes. To check your distributed, MSMQ, and RPC-driven company apps (you already know who you’re) please make sure that the next part areas are included in your venture check and launch schedule:
- Message Queue (MSMQ) Companies .
- MSMQ Lively Listing Area Companies Integration.
- MSMQ Triggers .
- HTTP, Routing Service and Multicasting Assist.
- MSMQ DCOM Proxy.
Automated testing will assist with these eventualities (particularly a testing platform that gives a “delta” or comparability between builds). Nonetheless, to your line-of-business purposes, getting the applying proprietor (doing UAT) to check and approve the outcomes remains to be important.
Home windows lifecycle replace
This part contains necessary modifications to servicing (and most safety updates) to Home windows desktop and server platforms.
- REMINDER: House, Professional, Professional Schooling, and Professional for Workstation editions of Home windows 11, model 21H2 reached finish of service on Oct. 10, 2023.
Every month, we break down the replace cycle into product households (as outlined by Microsoft) with the next fundamental groupings:
- Browsers (Microsoft IE and Edge).
- Microsoft Home windows (each desktop and server).
- Microsoft Workplace.
- Microsoft Change Server.
- Microsoft Improvement platforms (NET Core, .NET Core and Chakra Core).
- Adobe (or, should you get this far).
Browsers
Microsoft has launched 4 very small updates to the Chromium venture:
We’re fairly fortunate, as these are very lightweight updates. Nothing in comparison with the urgency and problem we used to expertise with updating Web Explorer. Add these updates to your normal patch launch schedule.
Home windows
Microsoft launched two essential updates and 38 patches rated necessary to the Home windows platform that cowl the next key elements:
- Home windows Kerberos.
- Home windows Hyper-V.
- Home windows Error log and reporting.
- Networking and Bluetooth.
- Home windows Shell and Lively Listing Group Coverage objects.
With solely two patches (CVE-2024-20674 and CVE-2024-20700) rated essential and no reported zero-days, that is one other comparatively mild month. Our focus for testing and deployment must be on administrator duties (validating backups, telemetry, and log information) and a few of the core inside options employed by builders for enterprise logic pushed distributed purposes. Add this replace to your normal Home windows platform launch schedule.
Microsoft Workplace
Microsoft launched simply two (CVE-2024-20677 and CVE-2024-21318) patches for Workplace and Microsoft SharePoint. These are low-impact updates that ought to not have an effect on how Excel or Phrases handles numbers or formulation. Add these Workplace updates to your normal launch schedule.
Microsoft Change Server
As in December, Microsoft didn’t launch any updates for Microsoft Change Server. Do not get too comfy. We expect the February replace goes to be an enormous one.
Microsoft growth platforms
Microsoft launched six updates affecting Microsoft .NET, Visible Studio, and the SQL Consumer characteristic. All updates are rated necessary. The SQL Consumer replace (CVE-2024-0056) would require some consideration. Scan your company Line of Enterprise (LOB) or inside purposes for .NET’s System.Knowledge.SqlClient dependencies. After getting a prioritized software listing, please add these updates to your normal developer launch schedule.
Adobe Reader (should you get this far)
No updates from Adobe for Reader or Acrobat this month however Microsoft has launched a single replace to the third social gathering database engine SQLite (CVE-2022-35737). This database engine replace ought to actually be included within the developer part, however strictly talking it is an open supply venture supported by Microsoft. Given our analysis on final 12 months’s patch and replace traits, we expect a larger-than-normal replace bundle for February. Automated testing goes to be key, with AI (most likely a “PatchGPT”) enjoying a big position in patch summaries, vulnerability assessments, and testing suggestions.
