{"id":"UBUNTU-CVE-2026-49014","details":"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.","modified":"2026-09-24T18:30:06.056563624Z","published":"2026-05-27T02:16:00Z","related":["USN-8812-1"],"upstream":["CVE-2026-49014"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-49014"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-49014"},{"type":"REPORT","url":"https://github.com/OSGeo/gdal/issues/14594"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-8812-1"}],"affected":[{"package":{"name":"gdal","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/gdal?arch=source&distro=esm-apps%2Fjammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.4.1+dfsg-1ubuntu0.1~esm1"}]}],"versions":["3.2.2+dfsg-3ubuntu2","3.4.0+dfsg-1","3.4.1+dfsg-1","3.4.1+dfsg-1build1","3.4.1+dfsg-1build3","3.4.1+dfsg-1build4"],"ecosystem_specific":{"binaries":[{"binary_version":"3.4.1+dfsg-1ubuntu0.1~esm1","binary_name":"gdal-bin"},{"binary_version":"3.4.1+dfsg-1ubuntu0.1~esm1","binary_name":"gdal-data"},{"binary_name":"libgdal-perl","binary_version":"3.4.1+dfsg-1ubuntu0.1~esm1"},{"binary_name":"libgdal30","binary_version":"3.4.1+dfsg-1ubuntu0.1~esm1"},{"binary_name":"python3-gdal","binary_version":"3.4.1+dfsg-1ubuntu0.1~esm1"}],"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-49014.json"}},{"package":{"name":"gdal","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/gdal?arch=source&distro=esm-apps%2Fnoble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.8.4+dfsg-3ubuntu3+esm1"}]}],"versions":["3.7.1+dfsg-1build1","3.8.0+dfsg-1","3.8.1+dfsg-1build1","3.8.2+dfsg-1","3.8.3+dfsg-1","3.8.4+dfsg-1","3.8.4+dfsg-3ubuntu2","3.8.4+dfsg-3ubuntu3"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"binary_name":"gdal-bin","binary_version":"3.8.4+dfsg-3ubuntu3+esm1"},{"binary_version":"3.8.4+dfsg-3ubuntu3+esm1","binary_name":"gdal-data"},{"binary_name":"gdal-plugins","binary_version":"3.8.4+dfsg-3ubuntu3+esm1"},{"binary_name":"libgdal34t64","binary_version":"3.8.4+dfsg-3ubuntu3+esm1"},{"binary_name":"python3-gdal","binary_version":"3.8.4+dfsg-3ubuntu3+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-49014.json"}},{"package":{"name":"gdal","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/gdal?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.10.2+dfsg-1build3","3.10.3+dfsg-1","3.10.3+dfsg-1build1","3.10.3+dfsg-1build2"],"ecosystem_specific":{"binaries":[{"binary_name":"gdal-bin","binary_version":"3.10.3+dfsg-1build2"},{"binary_name":"gdal-data","binary_version":"3.10.3+dfsg-1build2"},{"binary_name":"gdal-plugins","binary_version":"3.10.3+dfsg-1build2"},{"binary_version":"3.10.3+dfsg-1build2","binary_name":"libgdal36"},{"binary_name":"python3-gdal","binary_version":"3.10.3+dfsg-1build2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-49014.json"}},{"package":{"name":"gdal","ecosystem":"Ubuntu:Pro:26.04:LTS","purl":"pkg:deb/ubuntu/gdal?arch=source&distro=esm-apps%2Fresolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.12.2+dfsg-1ubuntu0.1~esm1"}]}],"versions":["3.10.3+dfsg-1build2","3.10.3+dfsg-1build3","3.11.4+dfsg-1","3.12.0+dfsg-1","3.12.1+dfsg-1","3.12.2+dfsg-1","3.12.2+dfsg-1build1","3.12.2+dfsg-1build2"],"ecosystem_specific":{"binaries":[{"binary_name":"gdal-bin","binary_version":"3.12.2+dfsg-1ubuntu0.1~esm1"},{"binary_name":"gdal-data","binary_version":"3.12.2+dfsg-1ubuntu0.1~esm1"},{"binary_name":"gdal-plugins","binary_version":"3.12.2+dfsg-1ubuntu0.1~esm1"},{"binary_name":"libgdal38","binary_version":"3.12.2+dfsg-1ubuntu0.1~esm1"},{"binary_version":"3.12.2+dfsg-1ubuntu0.1~esm1","binary_name":"python3-gdal"}],"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-49014.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
