CVE-2026-49014 Details
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.
A stack-based buffer overflow vulnerability has been identified in the GDAL library, specifically within the netCDF driver, versions 3.1.0 through 3.13.0. The issue arises in the 'scanForGeometryContainers' function, where a geometry attribute is read into a fixed-size stack buffer without proper validation of the attribute length. This flaw allows an attacker to embed an oversized geometry attribute in a crafted NetCDF file, leading to arbitrary code execution on the server running GDAL.
Users can update to the latest version of GDAL, where this vulnerability has been addressed. Instructions for updating GDAL can be found in the GDAL documentation.
