What is Open Babel?

Six years quiet, then a feature release and a fuzzing-driven security cleanup.

Open Babel is a chemical file format conversion and cheminformatics toolkit. After 3.1.0 in 2020 the project went effectively dormant, then returned in May 2026 with 3.2.0 — a release combining real 3D geometry work with the results of a sustained fuzzing campaign run through OSS-Fuzz, with reports from Cisco TALOS, Trail of Bits, and ADA Logics. The 3.2.1 follow-up continues that: a CVE in the MMD parser, sscanf validation across several formats, and a stack overflow in the Gaussian and cube readers.

What is SimpleSAMLphp?

Two maintenance branches, patched in lockstep, with release notes that say nothing but a checksum.

SimpleSAMLphp is running parallel 2.4 and 2.5 maintenance branches and patching both on the same day whenever a fix lands. The August releases are a coordinated security drop across the 2.5 line plus a 2.4 bugfix a day earlier. Release bodies carry no changelog text at all — just a download link, upgrade-notes pointer, and SHA256 checksums, so the feed tells operators when to patch but never what changed.

Open Babel vs SimpleSAMLphp: editorial side-by-side

O0.0

Six years quiet, then a feature release and a fuzzing-driven security cleanup.

◆ Current state

Open Babel is a chemical file format conversion and cheminformatics toolkit. After 3.1.0 in 2020 the project went effectively dormant, then returned in May 2026 with 3.2.0 — a release combining real 3D geometry work with the results of a sustained fuzzing campaign run through OSS-Fuzz, with reports from Cisco TALOS, Trail of Bits, and ADA Logics. The 3.2.1 follow-up continues that: a CVE in the MMD parser, sscanf validation across several formats, and a stack overflow in the Gaussian and cube readers.

◆ Where it's heading

The project has re-engaged around two things at once — improving initial 3D structure generation, and hardening the format parsers that make Open Babel useful in the first place. Because it reads dozens of chemical file formats, often from untrusted sources, the parser surface is the attack surface, and the release notes now devote as much space to crash fixes as to chemistry. The project says more bug-fix releases are expected through 2026.

◆ Prediction

Expect continued fuzz-driven parser fixes on the 3.2.x line, since the crash reports arrive from external infrastructure rather than a roadmap.

S5.0

Two maintenance branches, patched in lockstep, with release notes that say nothing but a checksum.

◆ Current state

SimpleSAMLphp is running parallel 2.4 and 2.5 maintenance branches and patching both on the same day whenever a fix lands. The August releases are a coordinated security drop across the 2.5 line plus a 2.4 bugfix a day earlier. Release bodies carry no changelog text at all — just a download link, upgrade-notes pointer, and SHA256 checksums, so the feed tells operators when to patch but never what changed.

◆ Where it's heading

This is pure maintenance cadence, not product development. The pattern across the last ten releases is consistent: security issues get simultaneous twin tags on both supported branches, everything else lands as branch-local bugfix points. The only release in the window that documented its own content was v2.4.6/v2.5.1 in May, which listed three GHSA advisories.

◆ Prediction

Expect the next tags to continue the twin-branch pattern — a paired 2.4.x and 2.5.x whenever an advisory lands, with content again deferred to the external changelog.
