Critical Updates

Oracle Critical Patch Update Advisory - January 2021 Description. A Critical Patch Update is a collection of patches for multiple security vulnerabilities. These patches address vulnerabilities in Oracle code and in third-party components included in Oracle products. Looking at the remaining Critical-rated updates, only one (surprisingly) impacts the browser. That patch corrects a bug within the JIT compiler. By performing actions in JavaScript, an attacker can trigger a memory corruption condition, which leads to code execution.

Critical product updates are packages that address a Microsoft-released security bulletin or that contain a change in time zone definitions. When in Mainstream Support, critical product updates are released as needed on a monthly basis for the most recently released CU and for the immediately previous CU. When in Extended Support, critical product updates are released as needed on a monthly basis for only the most recently released CU.

To get the latest version of Exchange 2019, download and install Cumulative Update 9 for Exchange Server 2019.

Servicing Stack Updates (SSU)

Critical Updates Required Valorant

The servicing stack is the code that installs other operating system updates. Additionally, it contains the component-based servicing stack (CBS), which is a key underlying component for several elements of Windows deployment, such as:

• DISM
• SFC
• Changing Windows features or roles
• Repairing components

The CBS is a small component that typically doesn't have updates released every month.
