Description
Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-j9pp-7wfg-q7fj. This link is maintained to preserve external references.
Original Description
A vulnerability has been found in Open Babel up to 3.1.1. The affected element is the function ChemKinFormat::ReadReactionQualifierLines of the file /src/formats/chemkinformat.cpp. The manipulation leads to null pointer dereference. The attack can only be performed from a local environment. The exploit has been disclosed to the public and may be used.
Affected versions
PyPI
| Package | Vulnerable | Fixed in |
|---|---|---|
| openbabel | < 3.2.0 |
3.2.0 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
openbabel PyPI → 3.2.0
- pip
pip install --upgrade "openbabel>=3.2.0"- poetry
poetry add "openbabel>=3.2.0"- uv
uv add "openbabel>=3.2.0"

Weakness
CWE-404: Improper Resource Shutdown or Release
The product does not release or incorrectly releases a resource before it is made available for re-use.
How to prevent it
- Requirements: Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, languages such as Java, Ruby, and Lisp perform automatic garbage collection that releases memory for objects that have been deallocated.
- Implementation: It is good practice to be responsible for freeing all resources you allocate and to be consistent with how and where you free memory in a function. If you allocate memory that you intend to free upon completion of the function, you must be sure to free the memory at all exit points for that function including error conditions.
- Implementation: Memory should be allocated/freed using matching functions such as malloc/free, new/delete, and new[]/delete[].
- Implementation: When releasing a complex object or structure, ensure that you properly dispose of all of its member components, not just the object itself.
