New CFEngine Hub packages released

Due to a number of vulnerabilities found in the version of Apache we bundle with CFEngine Hub, we have upgraded the CFEngine Hub packages to use an updated version of Apache. We upgrade from Apache 2.4.39 to Apache 2.4.41. We are now releasing a new version, CFEngine Hub 3.12.2-5. Only new Hub packages are being released, as no other packages are affected by these vulnerabilities.

Speeding up PostgreSQL ETL pipeline with the help of GODS

When working on the new Federated Reporting feature for CFEngine we had to solve the problem of collecting data from multiple CFEngine hubs (feeders) on a single hub (superhub). CFEngine hubs are using PostgreSQL to store data, so, more specifically, the problem was how to collect data from multiple PostgreSQL databases in one PostgreSQL database.

CFEngine 3.12.2-3, 3.14.0-2 released (mitigating CVE-2019-10164)

On [2019-07-29 Mon] we released new builds of our Enterprise Hub packages for 3.12.2 and 3.14.0. This release addresses CVE-2019-10164. PostgreSQL versions 10.x before 10.9 and versions 11.x before 11.4 are vulnerable to a stack-based buffer overflow. Any authenticated user can overflow a stack-based buffer by changing the user’s own password to a purpose-crafted value. This often suffices to execute arbitrary code as the PostgreSQL operating system account.

Writing custom service_methods

CFEngine provides the services promise type to manage the state of a given service. services type promises are an abstraction of agent bundles, they can be used to declare the desired state for a collection of things identified by a name. Most commonly services type promises are used to manage standard operating system services though they can be used for abstracting other logical states.

CVE-2019-9929 - internal authentication secrets leaked in logs

The CFEngine engineering team has recently discovered a severe security issue in the CFEngine Enterprise product. CFEngine is using some internal secrets for authentication to the Mission Portal API and the PostgreSQL database when running background maintenance tasks. These internal secrets are randomly generated during the installation process and stored in files which only the root user has access to.

CFEngine 3.12.2 LTS Released

We are happy to release the 2nd update to the CFEngine 3.12 LTS series. This update comes with many important stability and performance improvements and is thus well worth the upgrade from an older version of 3.12 LTS. CFEngine 3.12 LTS brings a lot of innovation, new features and improved performance to CFEngine, and allows you to make the most efficient use of your time. We are looking forward to your feedback on this release.
