A vulnerability was detected in Open Babel up to 3.1.1. This issue affects the function OBSmilesParser::ParseSmiles of the file /src/formats/smilesformat.cpp. Performing manipulation results in heap-based buffer overflow. The attack needs to be approached locally. The exploit is now public 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.
