ALAS2023-2026-1833


Amazon Linux 2023 Security Advisory: ALAS2023-2026-1833
Advisory Released Date: 2026-06-22
Advisory Updated Date: 2026-06-22
Severity: Important

Issue Overview:

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. (CVE-2026-49014)


Affected Packages:

gdal310


Issue Correction:
Run dnf update gdal310 --releasever 2023.12.20260622 or dnf update --advisory ALAS2023-2026-1833 --releasever 2023.12.20260622 to update your system.
