DescriptionNVD

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.

AnalysisAI

Arbitrary code execution in GDAL 3.1.0 through 3.13.0 is reachable through the netCDF driver, where scanForGeometryContainers (frmts/netcdf/netcdfsg.cpp) copies a CF-convention geometry attribute into a fixed-size stack buffer without checking its length. Any service or workflow that feeds attacker-supplied NetCDF files to GDAL can be coerced into overflowing the stack and running attacker code in the process context. …
