Machine-written summary

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

Open Babel versions before 3.2.0 are vulnerable to a NULL pointer dereference in the CACAO format parser, triggered in the CacaoFormat::SetHilderbrandt function. An attacker can cause a crash by getting a user to open a malicious CACAO file with obabel, the OBConversion API, or a language binding. Upgrade the openbabel package to version 3.2.0 or later.
