  "summary" : "Open Babel has out-of-bounds write in MOPAC translationVectors[] (UNIT CELL TRANSLATION)",
  "details" : "### Summary\n\nA memory-safety vulnerability in Open Babel's MOPAC output parser\nallowed an out-of-bounds write into the `translationVectors[]` array\nwhen reading the \"UNIT CELL TRANSLATION\" block of a crafted input\nfile.\n\n### Details\n\nThe MOPAC output reader stored translation vectors from the UNIT CELL\nTRANSLATION block into a fixed-size `translationVectors[]` array. A\nmalformed block could push more vectors than the array had slots,\ncausing a write past the end of the array. One of five\n`translationVectors[]` OOB writes in the TALOS 2022 batch.\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 MOPAC output file with the\n`obabel` tool, the `OBConversion` API, or any of the language\nbindings (Python, Ruby, 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/40e85213\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 by Cisco TALOS.",
