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 [HIGH] GDAL up to 3.13.0 netCDF Driver netcdfsg.cpp geometry stack-based overflow (Issue 14594 / EUVD-2026-32039)
A vulnerability, which was classified as critical, was found in GDAL up to 3.13.0. Affected by this issue is some unknown functionality of the file frmts/netcdf/netcdfsg.cpp of the component netCDF Driver. The manipulation of the argument geometry results in stack-based buffer overflow.
This vulnerability is known as CVE-2026-49014. Attacking locally is a requirement. No exploit is available.

CVE-2026-49014 [HIGH] CWE-121 GHSA-wphc-7cm7-8mf7: In GDAL 3
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.

Title: GDAL vulnerabilities
Summary: Several security issues were fixed in GDAL.
It was discovered that GDAL incorrectly handled certain netCDF files. An
attacker could possibly use this issue to execute arbitrary code. This issue
only affected Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, and Ubuntu 26.04 LTS.
(CVE-2026-49014)
It was discovered that GDAL incorrectly handled certain HDF-EOS files. An
attacker could possibly use this issue to cause a crash or execute arbitrary
code. (CVE-2026-8086, CVE-2026-8087, CVE-2026-8212, CVE-2026-8213)
It was discovered that GDAL incorrectly handled certain HDF-EOS file
metadata. An attacker could possibly use this issue to cause GDAL to crash,
resulting in a denial of service. (CVE-2026-8084, CVE-2026-8088)
