Finding Important Errata and CVE Information on ULN

I have recently received several questions about how to find information relating to critical security updates or important errata releases for Oracle Linux. I realized that perhaps people were not aware of the new features and improvements to Unbreakable Linux Network (ULN), which assist users with common administrative tasks. I wanted to take a quick moment to highlight for you some of the changes we have made. First, there are two links you will want to bookmark:

Each link will allow the user to evaluate what updates have been made available for Oracle Linux.

With https://linux.oracle.com/errata you are able to view all errata releases available, listed by type, severity, advisory, summary and release date. In addition, you are also able to filter this list by release and/or type (Bug, Security, Enhancement) and if you select an item from the list you will receive additional details regarding the errata, including a description, related CVEs and the packages updated by the errata.  You can also navigate to this same information by logging into ULN and selecting the 'Errata' tab from the options across the top.

For those who need information on security errata involving CVE identifiers (Common Vulnerabilities and Exposures) we have created https://linux.oracle.com/cve. This site allows you to gather information on important CVE identifiers, by providing a summary of all CVE offered through ULN. This summary is listed by CVE identifier and includes a brief synopsis and the release date. You can also filter the list by year. In addition, when you select a specific CVE identifier, you will receive additional details, such as information on CVSS v2 metrics as well as affected platforms.

We have been working to bring more features to ULN and these updates should provide more tools to simplify your administrative activities. Happy patching!

Introducing the Ksplice Offline client

We are excited to announce the availability of a new feature in our Ksplice service, known as the Ksplice offline client.  This new option eliminates the requirement on a direct connection to the internet to apply zero-downtime Ksplice patches.  The Ksplice offline client allows the user to create a local YUM repository which will mirror the Ksplice channel from ULN (Unbreakable Linux Network).  Once you have mirrored the channel on your local network, you simply apply the patch using the same Ksplice tools and commands you are already familiar with.  Ksplice is available to all customers with Oracle Linux Premier or Oracle Linux Premier Limited support.  Take a look at Wim's blog, where he provides an excellent example for how to setup and use this new service and if you are using Red Hat and want to try Ksplice, you can sign up for a 30 Day Free trial

You'll be able to perform real-world tasks with Oracle Linux and if you have questions you can ask for help from the Oracle experts through chat window. There's one caveat: you'll have to do a little homework ahead of time. Load the virtual images onto your laptop, find the instructions, and make sure everything is working properly. 

This wiki https://wikis.oracle.com/display/virtualsysadminday/Home explains what you need to do. If you have questions, ask them as comments to the wiki:https://wikis.oracle.com/display/virtualsysadminday/Home

Oracle Linux Track 

1. Oracle Linux Technology Overview - In this session we will go over the latest Oracle Linux features including tools for Linux administration such as the Unbreakable Linux Network (ULN) and public yum. We will also show you a demo of Ksplice zero downtime kernel updates, only available to Oracle Linux customers. You will see how easy it is to switch from Red Hat support to Oracle Linux support by using ULN. Last but not least, we’ll introduce the 3 hands-on labs that will follow this session in the Linux track.

2. HOL: Package Management -  In this lab session you will use the package management on Oracle Linux using RPM and yum. Some of the tasks that you will experience include listing installed packages, obtaining additional information about packages, searching for packages and installing/updating them as well as verifying package integrity and removing software. We’ll also review Linux services and run levels, how to start and stop them, checking the status of a particular service and enabling a service to be started automatically at system boot.

3. HOL: Storage Management - In this hands-on lab session, you will learn about storage management with LVM2, the Linux Logical Volume Manager, preparing block devices, creating physical and logical volumes, creating file systems on top of logical volumes, and resizing file systems dynamically. You will also practice setting up software RAID devices, configuring encrypted block devices.Btrfs File System - In this hands-on lab session, we will introduce you to Btrfs file system. You will be able to create and mount a Btrfs file system and learn to setup a mirrored/striped file system across multiple block devices. You’ll also learn how to add and remove block devices, and create file system snapshots.
