What is Clair?

Clair 4.10 RC can read SBOMs to match Java vulnerabilities.

Clair cut its first 4.10.0 release candidate on November 13, eleven months after 4.9.0. Its Java indexers can now read CycloneDX SBOM files and treat them as the source of truth, and Red Hat's VEX data now covers Maven advisories, so Java packages in Red Hat images can be matched. It also reduces memory use when many packages share a source package.

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.

Clair 4.10 RC can read SBOMs to match Java vulnerabilities.

◆ Current state

Clair cut its first 4.10.0 release candidate on November 13, eleven months after 4.9.0. Its Java indexers can now read CycloneDX SBOM files and treat them as the source of truth, and Red Hat's VEX data now covers Maven advisories, so Java packages in Red Hat images can be matched. It also reduces memory use when many packages share a source package.

◆ Where it's heading

Since 4.8 Clair has moved from Red Hat's older OVAL data to VEX, and each release follows Red Hat's security data more closely. 4.10 adds SBOMs as an input, so Clair can match what an image's own manifest declares, not only what it finds on disk.

◆ Prediction

More 4.10 release candidates and then a final are likely; the long gap between releases suggests that could take weeks.

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.
