An out-of-bounds write vulnerability exists in the MOL2 format attribute and value functionality of Open Babel 3.1.1 and master commit 530dbfa3. A specially crafted malformed file can lead to arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability.

The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:21190-1 advisory.

    Changes in openbabel:

    - Update to version 3.2.0:
      * Add an L-BFGS optimizer, used by default for gen3d and         conformer searches
      * New macrocycle ring builder (Dale codes) for better initial         3D geometry of large rings
      * Add KET (Ketcher JSON) and ChemicalJSON (.cjson) format         support
      * Drop Python 2 support; Python 3.13 supported
      * Faster, vectorized distance-geometry implementation
      * Full CMake 4 compatibility and modernized build
      * Backwards compatible with 3.0 and 3.1
      * Fix many crash and memory-safety bugs found via OSS-Fuzz         and TALOS, including the following security issues:
        CVE-2022-37331 (boo#1217676), CVE-2022-41793, CVE-2022-42885,         CVE-2022-43467, CVE-2022-43607, CVE-2022-44451,         CVE-2022-46280, CVE-2022-46289, CVE-2022-46290,         CVE-2022-46291, CVE-2022-46292, CVE-2022-46294,         CVE-2022-46295, CVE-2025-10994, CVE-2025-10995,         CVE-2025-10996, CVE-2025-10997, CVE-2025-10998,         CVE-2025-10999, CVE-2025-11000,         CVE-2026-2704 (boo#1258501), CVE-2026-2705 (boo#1258507) and         CVE-2026-3408 (boo#1259041)

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
