ZENworks Patch Updates

1.1 What is a Server Patch?

The server patches are released to improve the security, fix bugs or improve the performance of the product running on the server. The release version is considered the base server patch. If any server patch is baselined, then that becomes the base for future server patches. Server patches are cumulative.

1.2 What is Baseline Patch?

A baseline patch is a pre-requisite patch that is required for all future patches.

Once a patch is baselined, subsequent patches will be cumulative.

1.3 What is Agent Patch?

Similar to server patches, agent patches are released to improve the efficiency of the agents. Unlike server patches, agent patches are not cumulative.

1.4 Dependencies Between Agent and Server Patches

Depending on customer needs or due to binary dependencies as per implementation, agent patches might be dependent on the server patch, which implies that the server patch should be installed before installing the agent patch. If a server patch is required to be applied, then the readme provided with the server and agent patches will have cross-references to each other.

4.1 Server Patches

This section lists all the server patches that are released for ZENworks 2020 Update 3. As server patches are cumulative, you can install the latest patch that is released.

4.2 Agent Patches

Unlike server patches, agent patches are not cumulative. Hence, agent patches should be installed in the following release order:

The following table lists all the released agent patches, the latest released agent patch is at the end of the list:

4.3 Standalone Patches

A standalone patch is a type of update that can be applied independently. It is designed to fix a specific issue or vulnerability and can be installed without the need to update or upgrade the entire system. Standalone patches are typically small and focused and are often released in response to a bug that needs to be addressed quickly.

The following table lists the standalone patches:

4.4 Imaging Driver Updates

ZENworks Imaging driver updates are designed to enhance the functionality, compatibility, and performance of ZENworks imaging, making it easier for IT administrators to manage and deploy system images. ZENworks provides driver update packages that can be imported into ZENworks. These packages contain the latest drivers for supported hardware devices, allowing administrators to easily update driver libraries to ensure that when creating or deploying system images, the most current drivers are available.

4.5 Appliance Patches

Appliance patches are a type of update that is specifically designed for ZENworks Appliance. These patches are used to update and maintain the ZENworks Appliance, including the ZENworks server, operating system, and other components. These patches typically include bug fixes, security updates, and other improvements to the software.

For more information on applying Appliance patches, see Online Update in the ZENworks Appliance Deployment and Administration Reference.

4.6 Security Patches

Security patches are software updates that fix vulnerabilities that could be exploited by malicious attackers. These vulnerabilities might allow attackers to gain unauthorized access to the system, steal sensitive information, or carry out other actions.

Security patches are usually released when a security flaw or vulnerability is detected. These patches are typically released on a regular schedule or as soon as a critical vulnerability is detected.

Security patches are released to address security vulnerabilities, whereas other patches to improve performance, fix bugs, or add new features. Security patches are high-priority updates that should be installed immediately to ensure security.

4.7 Product Recognition Update (PRU)

A Product Recognition Update (PRU) is a type of software update that is used to identify and classify software products on managed devices. After applying, the PRU enables ZENworks to recognize and classify new software products that may not have been previously identified.

The PRU is important as it enables ZENworks to accurately identify and manage all software products on a managed device, including those that may be less common or not well known. This allows administrators to effectively monitor and manage software license compliance, security vulnerabilities, and software updates for all devices on the network.

PRUs are released regularly and are designed to be compatible with specific versions of ZENworks. It is important to ensure that the correct PRU is downloaded and applied to the appropriate ZENworks server or zone to ensure proper identification and management of software products.

For more information, see Downloading and Installing the PRU.
