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 Tailscale?

Tailscale makes a device's public IP a posture check, after three client security patches.

Tailscale is moving tailnet administration into policy and automation: MagicRoute, declarative node sharing, OAuth device provisioning and posture alerts all landed in October. The 1.104 client line underneath turned into a run of security patches, v1.104.2, v1.104.4 and v1.104.5, in under two weeks. November opened with the public IP address posture attribute going GA and the India relay servers moving from Bengaluru to Mumbai.

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.

5.0

Tailscale makes a device's public IP a posture check, after three client security patches.

◆ Current state

Tailscale is moving tailnet administration into policy and automation: MagicRoute, declarative node sharing, OAuth device provisioning and posture alerts all landed in October. The 1.104 client line underneath turned into a run of security patches, v1.104.2, v1.104.4 and v1.104.5, in under two weeks. November opened with the public IP address posture attribute going GA and the India relay servers moving from Bengaluru to Mumbai.

◆ Where it's heading

Device posture keeps gaining inputs: alerts and badges in October, now where a device connects from. Access rules are drifting from who you are toward what the device is and where it sits, all expressed in policy.

◆ Prediction

More posture attributes and posture-driven actions in the admin console look likely, given monitoring, alerts and now public IP shipped within a month.
