GHSA-wphc-7cm7-8mf7 GDAL: scanForGeometryContainers in the netCDF driver allows code execution via a stack-based buffer overflow

• PyPI gdal: >= 3.1.0, < 3.13.1 → fixed in 3.13.1

In GDAL 3.1.0 through 3.13.0, scanForGeometryContainers in the netCDF driver allows code execution via a stack-based buffer overflow. It reads a geometry attribute into a fixed-size stack buffer without validating the attribute length. The attacker embeds the exploit as an oversized geometry attribute in a crafted NetCDF file. This achieves arbitrary code execution on the server running GDAL. This is in frmts/netcdf/netcdfsg.cpp.
