How to Fix GHSA-q5fm-55c2-v6j9

To remediate this vulnerability, upgrade all affected Fiona dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

fiona fixed: 1.10b1 
pip install fiona>=1.10b1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show fiona

How to Check if You Are Affected

To determine whether your Python environment is affected by GHSA-q5fm-55c2-v6j9, inspect your installed packages using pip:

pip show fiona

Analyze the terminal output to locate any version of Fiona in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.10b1), your application is affected.

Note: The pip show fiona command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-190: Integer Overflow or Wraparound, where the product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. this occurs when an integer value is incremented to a value that is too large to store in the associated representation. when this occurs, the value may become a very small or negative number. In Fiona, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary Vulnerability scan of fiona shows [CVE-2023-45853](https://nvd.nist.gov/vuln/detail/CVE-2023-45853). The vulnerability is in GDAL, a dependency of fiona. ### Details Fiona depends on GDAL and GDAL has a port of minizip. MiniZip in zlib through 1.3 has an integer overflow and resultant heap-based buffer overflow in zipOpenNewFileInZip4_64 via a long filename, comment, or extra field. The GDAL project has addressed the CVE in version 3.8.0. See https://lists.osgeo.org/pipermail/gdal-dev/2023-November/057881.html. The Fiona version 1.9.6 wheels on PyPI include GDAL version 3.6.4 and thus could be vulnerable. All of the Fiona 1.10 pre-release wheels in PyPI include GDAL version 3.8.4 and are not vulnerable. ### Impact Systems which use GDAL versions prior to 3.8.0 to open unchecked zip files, whether in combination with fiona or not, could be susceptible to buffer overflows.
