A security vulnerability has been detected in Open Babel up to 3.1.1. This vulnerability affects the function zlib_stream::basic_unzip_streambuf::underflow in the library /src/zipstreamimpl.h. Such manipulation leads to memory corruption. Local access is required to approach this attack. The exploit has been disclosed publicly and may be used.

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)
