What is Cobbler?

Cobbler's 3.3 branch adds Kerberos single sign-on to the web UI.

Cobbler's public releases are all 3.3-branch backports. 3.3.10 adds Kerberos/GSSAPI single sign-on for the web UI through an Apache-terminated bridge and hardens the passthru authentication module against timing attacks. It follows the 3.3.8/3.3.9 pair, which brought openSUSE Leap 16 and Agama installer support, XCP-ng network installs and Python 3.13 support, and had to be re-cut after a CI publishing failure.

What is mod_auth_openidc?

mod_auth_openidc 2.4.20.4 closes a provider-to-host command execution path.

This Apache module implements OpenID Connect relying-party support, and its 2.4.20.x line has been a sustained security programme. 2.4.20.4 fixes a case where a provider could have a command run on the host via the exec: prefix in client metadata, sub-request session reuse that exposed protected content, a front-channel logout that could end another user's session, and quadratic memory use on large responses. It also adds interval-based access token refresh, cache metrics and a real readiness probe.

Cobbler's 3.3 branch adds Kerberos single sign-on to the web UI.

◆ Current state

Cobbler's public releases are all 3.3-branch backports. 3.3.10 adds Kerberos/GSSAPI single sign-on for the web UI through an Apache-terminated bridge and hardens the passthru authentication module against timing attacks. It follows the 3.3.8/3.3.9 pair, which brought openSUSE Leap 16 and Agama installer support, XCP-ng network installs and Python 3.13 support, and had to be re-cut after a CI publishing failure.

◆ Where it's heading

The branch is still gaining features aimed at enterprise data centres rather than winding down: new installer ecosystems in August, directory-backed single sign-on now. Authentication has been a recurring concern since the CVE-2024-47533 admin-API bypass. Releases continue to arrive as rollups from main.

◆ Prediction

Expect further 3.3.x rollups; whether the main line cuts a 3.4 is not visible from these entries.

2.5

mod_auth_openidc 2.4.20.4 closes a provider-to-host command execution path.

◆ Current state

This Apache module implements OpenID Connect relying-party support, and its 2.4.20.x line has been a sustained security programme. 2.4.20.4 fixes a case where a provider could have a command run on the host via the exec: prefix in client metadata, sub-request session reuse that exposed protected content, a front-channel logout that could end another user's session, and quadratic memory use on large responses. It also adds interval-based access token refresh, cache metrics and a real readiness probe.

◆ Where it's heading

Each 2.4.20.x release has taken one area through review: session crypto, the state-cookie parser, cache storage, and now metadata handling, sub-requests and logout. Observability is the second thread, with Prometheus self-health metrics and trace propagation added in this release.

◆ Prediction

Further 2.4.20.x security releases are likely while the review continues. The sub-request change can trigger re-authentication where OIDCStripCookies or POST-body tokens are used, so operators should test before upgrading.
