CVE-2026-49014
"GDAL NetCDF Driver Stack Buffer Overflow"
Description
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.
