pip show openbabel
How to Check if You Are Affected
To determine whether your Python environment is affected by GHSA-95gx-jmhp-5p29, inspect your installed packages using pip:
pip show openbabel
Analyze the terminal output to locate any version of Duplicate Advisory in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.2.0), your application is affected.
Note: The pip show openbabel command checks currently installed packages in your active Python environment.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer, where the product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. this may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data. In Duplicate Advisory, software state validation or input boundaries are circumvented during processing.
