GHSA-M982-7Q3H-R784

Vulnerability from github – Published: 2026-07-01 17:42 – Updated: 2026-07-01 17:42

Summary

Open Babel has out-of-bounds read in PQS lowerit (pre-buffer read)

Details

Summary

A memory-safety vulnerability in Open Babel's PQS parser caused an out-of-bounds (pre-buffer) read when reading a crafted input file.

Details

The flaw was in the lowerit helper used by the PQS parser. A malformed input caused the helper to read one or more bytes before the start of its input buffer.

Impact

Open Babel is a C++ library and CLI used to read and write chemistry file formats; it is shipped by Linux distributions and embedded in services that may parse untrusted input. Triggering this vulnerability requires the victim to open a malicious PQS file with the obabel tool, the OBConversion API, or any of the language bindings (Python, Ruby, Java, R, Perl, C#, PHP).

Affected versions

All releases up to and including 3.1.1.

Patched version

3.2.0 (released 2026-05-26).

Patch

Fix commit: https://github.com/openbabel/openbabel/commit/f4a5ebae Fixes consolidated in #2913.

A minimized reproducer for this CVE is checked in under test/files/fuzz_regress/ and is exercised on every CI build under ASAN+UBSAN by the fuzzregresstest harness.

Credit

  "details": "### Summary\n\nA memory-safety vulnerability in Open Babel\u0027s PQS parser caused an\nout-of-bounds (pre-buffer) read when reading a crafted input file.\n\n### Details\n\nThe flaw was in the `lowerit` helper used by the PQS parser. A\nmalformed input caused the helper to read one or more bytes before\nthe start of its input buffer.\n\n### Impact\n\nOpen Babel is a C++ library and CLI used to read and write chemistry\nfile formats; it is shipped by Linux distributions and embedded in\nservices that may parse untrusted input. Triggering this vulnerability\nrequires the victim to open a malicious PQS file with the `obabel`\ntool, the `OBConversion` API, or any of the language bindings (Python,\nRuby, Java, R, Perl, C#, PHP).\n\n### Affected versions\n\nAll releases up to and including 3.1.1.\n\n### Patched version\n\n3.2.0 (released 2026-05-26).\n\n### Patch\n\nFix commit: https://github.com/openbabel/openbabel/commit/f4a5ebae\nFixes consolidated in #2913.\n\nA minimized reproducer for this CVE is checked in under\n`test/files/fuzz_regress/` and is exercised on every CI build under\nASAN+UBSAN by the `fuzzregresstest` harness.\n\n### Credit\n\nReported via OSS-Fuzz.",

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
