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 Snort 3?

Snort 3.13.2 is a broad bounds-checking sweep across SMB, HTTP and industrial protocol parsers

Snort 3.13.2.0, released 5 November, is a large roll-up that mostly bounds and validates input: SMB header checks, a fix for an SMB inspection bypass via crafted keep-alive lengths, OLE2 VBA heap fixes, MMS and DNP3 length limits, and a heap out-of-bounds write in the Unix transport. It also adds new http_inspect alerts for malformed or oversized headers, file cache control commands, and appid support for MCP inspector verdicts. The 3.13 line requires the Talos LightSPD rules package from 14 September onward because of an API bump in 3.13.0.0.

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

Snort 3.13.2 is a broad bounds-checking sweep across SMB, HTTP and industrial protocol parsers

◆ Current state

Snort 3.13.2.0, released 5 November, is a large roll-up that mostly bounds and validates input: SMB header checks, a fix for an SMB inspection bypass via crafted keep-alive lengths, OLE2 VBA heap fixes, MMS and DNP3 length limits, and a heap out-of-bounds write in the Unix transport. It also adds new http_inspect alerts for malformed or oversized headers, file cache control commands, and appid support for MCP inspector verdicts. The 3.13 line requires the Talos LightSPD rules package from 14 September onward because of an API bump in 3.13.0.0.

◆ Where it's heading

Memory safety and input bounding now dominate every release, with feature work limited to new alerts and operator controls. The appid line about MCP inspector verdicts is the one hint that Snort is starting to classify AI agent traffic, though the entry gives no detail.

◆ Prediction

Expect more parser hardening in 3.13.3 and a 3.12.x maintenance release alongside it; whether MCP inspection becomes a documented feature is unclear from these entries.
