What is YARA?

YARA 4.6.0 is the first minor in two years, and it is almost entirely bounds checks.

4.6.0 is YARA's first minor release since 4.5.0 in September 2024. It adds yr_get_version, nine more e_machine values in the elf module and a man-page sync; everything else is bug fixes across compiled-rule loading, the regex engine, the VM, ELF handling and Authenticode. Loading a compiled rule file now validates indices, external variables, arena buffers and Aho-Corasick states. The release credits Ada Logics and Anthropic among its contributors.

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.

YARA 4.6.0 is the first minor in two years, and it is almost entirely bounds checks.

◆ Current state

4.6.0 is YARA's first minor release since 4.5.0 in September 2024. It adds yr_get_version, nine more e_machine values in the elf module and a man-page sync; everything else is bug fixes across compiled-rule loading, the regex engine, the VM, ELF handling and Authenticode. Loading a compiled rule file now validates indices, external variables, arena buffers and Aho-Corasick states. The release credits Ada Logics and Anthropic among its contributors.

◆ Where it's heading

The parser-under-pressure reading holds, with wider scope. Earlier patches bounded single values; this release treats compiled rules and regex input as hostile throughout. Fixes for exponential growth on nested regex repeats and infinite loops show the review now covers resource exhaustion as well as corruption.

◆ Prediction

Expect 4.6.x patches in the same files, since this list is long and contributor-driven. Nothing here signals new language features; the three additions are small.

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.
