Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Open Babel versions before 3.2.0 (PyPI package openbabel, as listed) contain a NULL pointer dereference in the ChemKin parser's reaction qualifier handling, triggered by a malformed record. An attacker needs a victim to open a crafted ChemKin file with obabel, the OBConversion API, or a language binding, which can cause a crash. Upgrade to 3.2.0 or later.
