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 Routinator?

Routinator 0.16 now validates ASPA and BGPsec, and runs strict, by default

Routinator is a mature RPKI validator with a slow, release-candidate-gated cadence. 0.16.0 shipped on 6 November with the candidate's defaults: ASPA and BGPsec on, strict validation on, the old flags replaced by --disable-aspa, --disable-bgpsec and --relaxed, plus RSC (RFC 9323), SLURM v2 and a new repository logging scheme that changes the /status JSON. Three days later 0.16.1 fixed a crash on start when TLS is enabled for the HTTP or RTR servers.

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.

Routinator 0.16 now validates ASPA and BGPsec, and runs strict, by default

◆ Current state

Routinator is a mature RPKI validator with a slow, release-candidate-gated cadence. 0.16.0 shipped on 6 November with the candidate's defaults: ASPA and BGPsec on, strict validation on, the old flags replaced by --disable-aspa, --disable-bgpsec and --relaxed, plus RSC (RFC 9323), SLURM v2 and a new repository logging scheme that changes the /status JSON. Three days later 0.16.1 fixed a crash on start when TLS is enabled for the HTTP or RTR servers.

◆ Where it's heading

After a year of security fixes, Routinator has moved route-origin hardening from opt-in to default, which shifts the work onto operators who must now opt out. The quick 0.16.1 suggests the new release is meeting more varied deployments than the candidate did.

◆ Prediction

Further 0.16.x fixes as operators upgrade into the new defaults are the likely next releases; nothing in the entries points to new features soon.
