    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.
