Details
Summary Vulnerability scan of fiona shows 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 zipOpenNewFileInZip464 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.
