Update Patch



Patches are software and operating system (OS) updates that address security vulnerabilities within a program or product. Software vendors may choose to release updates to fix performance bugs, as well as to provide enhanced security features.




Update Patch



When software updates become available, vendors usually put them on their websites for users to download. Install updates as soon as possible to protect your computer, phone, or other digital device against attackers who would take advantage of system vulnerabilities. Attackers may target vulnerabilities for months or even years after updates are available.


If possible, only apply automatic updates from trusted network locations (e.g., home, work). Avoid updating software (automatically or manually) while connected to untrusted networks (e.g., airport, hotel, coffee shop). If updates must be installed over an untrusted network, use a Virtual Private Network connection to a trusted network and apply updates.


Sometimes vendors will discontinue support for a software program or issue software updates for it (also known as end-of-life [EOL] software). Continued use of EOL software poses consequential risk to your system that can allow an attacker to exploit security vulnerabilities. The use of unsupported software can also cause software compatibility issues as well as decreased system performance and productivity.


New vulnerabilities are continually emerging, but the best defense against attackers exploiting patched vulnerabilities is simple: keep your software up to date. This is the most effective measure you can take to protect your computer, phone, and other digital devices.


Oracle has released its Critical Patch Update for October 2022. This update addresses 366 vulnerabilities across multiple products. A remote attacker could exploit some of these vulnerabilities to take control of an affected system.


A patch filter consists of a key and a set of values. The filter key is a patch property. For example, the available filter keys for WINDOWS are PATCH_SET , PRODUCT , PRODUCT_FAMILY , CLASSIFICATION , and MSRC_SEVERITY .


The filter values define a matching criterion for the patch property indicated by the key. For example, if the filter key is PRODUCT and the filter values are ["Office 2013", "Office 2016"] , then the filter accepts all patches where product name is either "Office 2013" or "Office 2016". The filter values can be exact values for the patch property given as a key, or a wildcard (*), which matches all values.


You can view lists of valid values for the patch properties by running the DescribePatchProperties command. For information about which patch properties can be used with each major operating system, see DescribePatchProperties .


For information about accepted formats for lists of approved patches and rejected patches, see About package name formats for approved and rejected patch lists in the Amazon Web Services Systems Manager User Guide .


The specific operating system versions a patch repository applies to, such as "Ubuntu16.04", "AmazonLinux2016.09", "RedhatEnterpriseLinux7.2" or "Suse12.7". For lists of supported product values, see PatchFilter .


This most recent patch for Valheim has been implemented to fix issues where Xbox and PC players got different heightmaps, resulting in a bug that caused character models to levitate or walk below ground-level.


The output shows that the running Pods have different names from the Pods thatwere running previously. The Deployment terminated the old Pods and created twonew Pods that comply with the updated Deployment spec. The 2/2 indicates thateach Pod has two Containers:


The patch you did in the preceding exercise is called a strategic merge patch.Notice that the patch did not replace the containers list. Instead it added a newContainer to the list. In other words, the list in the patch was merged with theexisting list. This is not always what happens when you use a strategic merge patch on a list.In some cases, the list is replaced, not merged.


With a strategic merge patch, a list is either replaced or merged depending on itspatch strategy. The patch strategy is specified by the value of the patchStrategy keyin a field tag in the Kubernetes source code. For example, the Containers field of PodSpecstruct has a patchStrategy of merge:


Notice that the tolerations list in the PodSpec was replaced, not merged. This is becausethe Tolerations field of PodSpec does not have a patchStrategy key in its field tag. So thestrategic merge patch uses the default patch strategy, which is replace.


A strategic merge patch is different from aJSON merge patch.With a JSON merge patch, if youwant to update a list, you have to specify the entire new list. And the new list completelyreplaces the existing list.


The retainKeys strategy does not work for all objects. It only works when the value of the patchStrategy key in a field tag in the Kubernetes source code contains retainKeys. For example, the Strategy field of the DeploymentSpec struct has a patchStrategy of retainKeys:


The flag --subresource=[subresource-name] is used with kubectl commands like get, patch,edit and replace to fetch and update status and scale subresources of the resources(applicable for kubectl version v1.24 or more). This flag is used with all the API resources(built-in and CRs) that have status or scale subresource. Deployment is one of theexamples which supports these subresources.


In this exercise, you used kubectl patch to change the live configurationof a Deployment object. You did not change the configuration file that you originally used tocreate the Deployment object. Other commands for updating API objects includekubectl annotate,kubectl edit,kubectl replace,kubectl scale,andkubectl apply.


Our Home Updater is a free, easy-to-use program that keeps over 300 applications up-to-date on your computer. It is an easy way to update or install a large list of programs on to your computer.


If you've gotten multiple update messages, make sure the last update is fully installed. Some browsers download to a separate update window. In these browsers, double-click the Reader or Acrobat file to complete the installation.


Quarterly update (Q): A scheduled update that includes functional improvements, new security updates, and previously released out-of-cycle patch updates. For Reader, these updates are sometimes available as full installers.


Optional Update: An update targeted at a narrow set of functional fixes with limited impact. Adobe recommends that you apply these patches if you are seeing an impact by one of more of the functional fixes being delivered.


Note: Continuous releases, quarterly updates, out-of-cycle patches and optional updates can provide security enhancements. Adobe recommends that all updates and patches be applied when available.


Note We highly recommend that you install the latest security update available. They provide advanced protections from the latest security threats. They also provide capabilities that we have added to support migration.
