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.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - 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)

The remote Ubuntu 14.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 26.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8812-1 advisory.

    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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2026-1833 advisory.

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
