{"id":"CVE-2025-48071","summary":"OpenEXR's Forged Unpacked Size can Lead to Heap-Based Buffer Overflow in Deep Scanline Parsing","details":"OpenEXR provides the specification and reference implementation of the EXR file format, an image storage format for the motion picture industry. In versions 3.3.2 through 3.3.0, there is a heap-based buffer overflow during a write operation when decompressing ZIPS-packed deep scan-line EXR files with a maliciously forged chunk header. This is fixed in version 3.3.3.","aliases":["GHSA-h45x-qhg2-q375","PYSEC-2026-1747"],"modified":"2026-08-27T09:37:40.465997Z","published":"2025-07-31T20:13:14.436Z","related":["openSUSE-SU-2025:15415-1"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-122"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/48xxx/CVE-2025-48071.json"},"references":[{"type":"WEB","url":"https://github.com/AcademySoftwareFoundation/openexr/releases/tag/v3.3.3"},{"type":"ADVISORY","url":"https://github.com/AcademySoftwareFoundation/openexr/security/advisories/GHSA-h45x-qhg2-q375"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/48xxx/CVE-2025-48071.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-48071"},{"type":"FIX","url":"https://github.com/AcademySoftwareFoundation/openexr/commit/916cc729e24aa16b86d82813f6e136340ab2876f"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/academysoftwarefoundation/openexr","events":[{"introduced":"c7d3eac70ccde2c4ed484c6638b83ba872f71464"},{"fixed":"da760aa4b6bee4b9d74b8c6a151221b035fc47b7"},{"fixed":"916cc729e24aa16b86d82813f6e136340ab2876f"}],"database_specific":{"cpe":"cpe:2.3:a:openexr:openexr:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"3.3.0"},{"fixed":"3.3.3"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["v3.3.3-rc","v3.3.2-rc4","v3.3.2","v3.3.2-rc3","v3.3.2-rc2","v3.3.2-rc","v3.3.1-rc","v3.3.1","v3.3.0-rc2","v3.3.0"],"database_specific":{"vanir_signatures":[{"signature_type":"Line","signature_version":"v1","source":"https://github.com/academysoftwarefoundation/openexr/commit/916cc729e24aa16b86d82813f6e136340ab2876f","target":{"file":"src/lib/OpenEXRCore/internal_zip.c"},"deprecated":false,"digest":{"line_hashes":["236554309323941681442902780184542278622","215692014661767331559617667733471439449","17146640194290669469922204778186888796","253648945683594711445023860716404119097"],"threshold":0.9},"id":"CVE-2025-48071-b9cfc41c"},{"deprecated":false,"digest":{"function_hash":"189907468790423021866405460083792139662","length":468},"id":"CVE-2025-48071-f6e27b48","signature_type":"Function","signature_version":"v1","source":"https://github.com/academysoftwarefoundation/openexr/commit/916cc729e24aa16b86d82813f6e136340ab2876f","target":{"file":"src/lib/OpenEXRCore/internal_zip.c","function":"undo_zip_impl"}}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-48071.json","vanir_signatures_modified":"2026-08-27T09:37:40Z"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
