Technical details
A stack-based buffer overflow exists in GDAL's netCDF driver within the `scanForGeometryContainers` function in `frmts/netcdf/netcdfsg.cpp`. The vulnerability is caused by reading a geometry attribute into a fixed-size stack buffer using `nc_get_att_text()` without first validating the attribute's length. An attacker can exploit this by embedding an oversized geometry attribute in a malicious NetCDF file. While the attack vector is local, it requires no specific privileges or user interaction beyond the library attempting to parse the file. The issue is addressed in version 3.13.1 by implementing length checks before reading attributes.
