The first Patch Tuesday of the decade has arrived with a bang. There’s been a lot of buzz regarding essential updates that were set to be released this January, and sure enough, the vendors have delivered! We’ve consolidated all the important fixes and more so that you can get off to a great start in diligently patching and safeguarding your systems this year. Before getting into the gritty details, here’s a quick overview of Patch Tuesday.
What is Patch Tuesday?
Microsoft regularly releases security and non-security updates to address vulnerabilities in its software, as well as upgrades for its applications and operating systems (OSs). Patch Tuesday is the specific day that all the relevant updates for Windows OS and other components and applications are officially posted on the Microsoft Bulletin.
When is Patch Tuesday?
Patch Tuesday is coined as such because it falls on the second Tuesday of every month. Microsoft released the first Patch Tuesday updates in October 2003, and they have faithfully upheld this tradition ever since.
Highlights of Patch Tuesday January 2020
The first Patch Tuesday of the year comes with fixes for 50 vulnerabilities. Out of these, 8 are rated Critical and 41 are rated Important.
Patch for the vulnerability in CRYPT32.DLL rated Important
The much anticipated patch for the spoofing vulnerability in the usermode cryptographic library CRYPT32.DLL, which affects Windows 10 machines, has been rated Important as it has not been used in active cyberattacks yet. The CVE ID of this vulnerability is CVE-2020-0601. If unpatched, this vulnerability could allow attackers to create a code-signing certificate, making a malicious executable look like it’s from a trusted source. This could easily pave the way for ransomware and malware being trusted and installed on endpoints.
Vulnerabilities in Remote Desktop Protocol (RDP) software patched
In keeping with trends of vulnerabilities in RDP-related software, this Patch Tuesday also fixes five vulnerabilities in Remote Desktop Gateway Server, Remote Desktop Client, and Remote Desktop Web Access. The CVE IDs are as follows: CVE-2020-0609, CVE-2020-0610, CVE-2020-0611, CVE-2020-0612, and CVE-2020-0637.

Best practices to handle Microsoft Patch Tuesday updates for January 2020
Patching and updating all your endpoints might seem like an impossible task, but there are best practices you can follow to streamline the patching process:
- Prioritize patching for Critical vulnerabilities first. The eight Critical vulnerabilities this Patch Tuesday are CVE-2020-0603, CVE-2020-0605, CVE-2020-0606, CVE-2020-0609, CVE-2020-0610, CVE-2020-0611, CVE-2020-0640, and CVE-2020-0646.
- Automate all other Important and Moderate updates after that.
- Schedule updates to go out during non-business hours for optimal user convenience and conservation of bandwidth.
- Create a test group to verify the stability of Patch Tuesday updates before mass deployment to systems and servers in your network.
- Decline less critical updates and dispatch them only after the important issues have been addressed.
- Postpone or schedule reboots for critical machines and servers.
- Run patch reports to ensure network endpoints are up-to-date with the latest patches.
