What is Apereo CAS?

Apereo CAS 8.1.0 reaches a third release candidate with 8.0.0 still not final.

CAS runs long release-candidate trains. 8.0.0 reached RC6 in June without a final in this feed, and the 8.1.0 line has since moved through RC1 in August, RC2 in September and RC3 in October. A 7.3.7.1 patch in June fixed a published OIDC vulnerability on the maintenance branch. The release entries list only documentation links and contributor credits, so their contents are not visible here.

What is Icinga?

Icinga 2 has now shipped security releases in July, August and October.

Icinga 2 patches security issues as simultaneous releases across its supported branches. On 28 October v2.16.6 and v2.15.7 fixed mail-flag injection in the default notification scripts plus several API issues. That follows the August pair closing a /v1/events permission bypass and a node-to-node memory exhaustion path, and the July trio covering 2.14, 2.15 and 2.16 with fixes for unauthenticated takeover and crash bugs.

2.5

Apereo CAS 8.1.0 reaches a third release candidate with 8.0.0 still not final.

◆ Current state

CAS runs long release-candidate trains. 8.0.0 reached RC6 in June without a final in this feed, and the 8.1.0 line has since moved through RC1 in August, RC2 in September and RC3 in October. A 7.3.7.1 patch in June fixed a published OIDC vulnerability on the maintenance branch. The release entries list only documentation links and contributor credits, so their contents are not visible here.

◆ Where it's heading

Candidates arrive about monthly, and 8.1 has overtaken 8.0 as the active line. Without notes in the entries, the feed tracks timing rather than content.

◆ Prediction

An 8.1.0-RC4 or an 8.1.0 final is the next likely entry, on the same roughly monthly rhythm.

Icinga 2 has now shipped security releases in July, August and October.

◆ Current state

Icinga 2 patches security issues as simultaneous releases across its supported branches. On 28 October v2.16.6 and v2.15.7 fixed mail-flag injection in the default notification scripts plus several API issues. That follows the August pair closing a /v1/events permission bypass and a node-to-node memory exhaustion path, and the July trio covering 2.14, 2.15 and 2.16 with fixes for unauthenticated takeover and crash bugs.

◆ Where it's heading

Three security rounds in four months point to a sustained audit of the API and cluster protocol, now reaching the shipped notification scripts. The 2.14 branch got the July fixes but no 2.14 release appears in the feed for August or October, which suggests its support is narrowing.

◆ Prediction

Further paired 2.16.x and 2.15.x security releases are likely while the audit continues; watch whether 2.14 gets the October fixes at all.
