  • Subscription-manager for the former Red Hat Network User: Part 4 - Understanding Subscription Manifests

    working title: of Men, Mice and Manifests Overview With the introduction of the newer Systems Management tools such as Satellite 6, we introduced a new concept, the Subscription Manifest (which are different from Satellite 5 Entitlement XML certificates), as the means to import Subscriptions into Satellite for the purposes of synchronizing content and attaching subscriptions to systems. What is a subscription manifest? A subscription manifest is a digitally signed zip file containing: A...

  • Making systems ready for Satellite 6.2's remote execution

    Satellite 6.2 ships with the much anticipated remote execution feature, which allows you to run scripts and jobs on a group of systems and then gather and view the output in the Satellite interface. Remote Execution by itself works fine out of the box for new machines, but already existing machines need to be bootstrapped by adding an SSH public key to root's ~/.ssh/authorized_keys. You can use Puppet to do this - assuming you are using Puppet at all - in two distinct ways: - you can use a full...

  • Satellite5, spacewalk-clone-by-date, and you!

    INTRODUCTION A typical workflow for a Satellite 5 installtion involves maintaining strict control over exactly what changes are available to registered systems. This is accomplished by cloning the channels synchronized from Red Hat Network, and limiting the clones to a given subset of the 'current' state of the original channel. spacewalk-clone-by-date is a tool available as part of the Satellite 5 subscription which aims to ease the process of creating and maintaining cloned channels. However...

  • Using the Java Security Manager in Enterprise Application Platform 7

    JBoss Enterprise Application Platform 7 allows the definition of Java Security Policies per application. The way it's implemented means that we'll also be able to define security policies per module, in addition to define one per application. The ability to apply the Java Security Manager per application, or per module in EAP 7, makes it a versatile tool in the mitigation of serious security issues, or useful for applications with strict security requirements. The main difference between EAP 6...

  • Java Deserialization attacks on JBoss Middleware

    Recent research by Chris Frohoff and Gabriel Lawrence has exposed gadget chains in various libraries that allow code to be executed during object deserialization in Java. They've done some excellent research, including publishing some code that allows anyone to serialize a malicious payload that when deserialized runs the operating system command of their choice, as the user which started the Java Virtual Machine (JVM). The vulnerabilities are not with the gadget chains themselves but with the...

  • Redefining how we share our security data.

    Red Hat Product Security has long provided various bits of machine-consumable information to customers and users via our Security Data page. Today we are pleased to announce that we have made it even easier to access and parse this data through our new Security Data API service. While we have provided this information since January 2005, it required end users to download the content from the site, which meant you either downloaded many files and kept a local copy, or you were downloading large...

  • How Red Hat uses CVSSv3 to Assist in Rating Flaws

    Humans have been measuring risk since the dawn of time. "I'm hungry, do I go outside my awesome cave here and forage for food? There might be something bigger, scarier, and hungrier than me out there...maybe I should wait?" Successfully navigating through life is a series of Risk/Reward calculations made each and every day. Sometimes, ideally, the choices are small ("Do I want fries with that?") while others can lead to catastrophic outcomes if the scenario isn't fully thought-through and...

  • The Answer is always the same: Layers of Security

    There is a common misperception that now that containers support seccomp we no longer need SELinux to help protect our systems. WRONG. The big weakness in containers is the container possesses the ability to interact with the host kernel and the host file systems. Securing the container processes is all about shrinking the attack surface on the host OS and more specifically on the host kernel. seccomp does a great job of shrinking the attack surface on the kernel. The idea is to limit the...

  • Security risks with higher level languages in middleware products

    Java-based high-level application-specific languages provide significant flexibility when using middleware products such as BRMS. This flexibility comes at a price as there are significant security concerns in their use. In this article the usage of Drools language and MVEL in JBoss BRMS is looked at to demonstrate some of these concerns. Other middleware products might be exposed to similar risks. Java is an extremely feature-rich portable language that is used to build a great range of...

    When a major security risk like the new OpenSSL DROWN vulnerability strikes, you have to plan your response. Generally, you should start outside (Internet-facing) and work your way inside, and prioritize those servers which expose vulnerable network services over those that simply have an older package installed. For more information on the DROWN security vulnerability (CVE-2016-0800) please refer to this Vulnerability Article. Identifying risk To help you respond to DROWN, Red Hat Insights...

  • Go home SSLv2, you’re DROWNing

    The SSLv2 protocol had its 21st birthday last month, but it’s no cause to celebrate with an alcohol beverage, since the protocol was already deprecated when it turned 18. Announced today is an attack called DROWN that takes advantage of systems still using SSLv2. Many cryptographic libraries already disable SSLv2 by default, and updates from the OpenSSL project and Red Hat today catch up. What is DROWN? CVE-2016-0800, also known as DROWN, stands for Decrypting RSA using Obsolete and Weakened...
