{"id":"CVE-2026-59983","summary":"OpenEXR: Out-of-bounds read in DeepTiledInputFile sample-count table decode on ILP32","details":"OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. OpenEXR versions before 3.2.11, 3.3.0 through 3.3.12, and 3.4.0 through 3.4.13 are vulnerable on ILP32 builds to an out-of-bounds read. The vulnerability is reached when a crafted uncompressed deep-tile EXR causes the sample-count table size calculation in OpenEXRCore decoding.c to wrap before unpack_sample_table() iterates over the full attacker-controlled tile dimensions, allowing denial of service. This issue is fixed in versions 3.2.11, 3.3.13, and 3.4.14.","aliases":["GHSA-p42q-g5c9-mh9w"],"modified":"2026-10-28T11:18:14.572084761Z","published":"2026-08-25T18:02:42.977Z","related":["SUSE-SU-2026:23604-1","openSUSE-SU-2026:11612-1","openSUSE-SU-2026:12184-1","openSUSE-SU-2026:21737-1"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-125"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/59xxx/CVE-2026-59983.json"},"references":[{"type":"ADVISORY","url":"https://github.com/AcademySoftwareFoundation/openexr/security/advisories/GHSA-p42q-g5c9-mh9w"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/59xxx/CVE-2026-59983.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-59983"},{"type":"FIX","url":"https://github.com/AcademySoftwareFoundation/openexr/commit/0efec58d2d28a0ee322f5028dee6fb57d459580e"},{"type":"FIX","url":"https://github.com/AcademySoftwareFoundation/openexr/commit/78e91146fceeee317820a146ba99a96f380945b8"},{"type":"FIX","url":"https://github.com/AcademySoftwareFoundation/openexr/commit/f0e404f7298cd8563a1d30a64a1c982dbd68fc49"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/academysoftwarefoundation/openexr","events":[{"introduced":"0"},{"fixed":"ba4b1af3a096e8f69e1836b210976585189a5fca"},{"introduced":"c7d3eac70ccde2c4ed484c6638b83ba872f71464"},{"fixed":"ca50a6bb1f64c4d53362e4b67aec33e67cb7d425"},{"introduced":"20a65852895894434bea88613f6d29ac8e88bd6e"},{"fixed":"777d231a179de1711d2a942810d9559216ab3f4c"},{"fixed":"0efec58d2d28a0ee322f5028dee6fb57d459580e"},{"fixed":"78e91146fceeee317820a146ba99a96f380945b8"},{"fixed":"f0e404f7298cd8563a1d30a64a1c982dbd68fc49"}],"database_specific":{"extracted_events":[{"strategy":"StringRangeExpression","range":[{"introduced":"0"},{"fixed":"3.2.11"}],"source":"AFFECTED_FIELD"},{"range":[{"introduced":"3.3.0"},{"fixed":"3.3.13"}],"source":"AFFECTED_FIELD","strategy":"StringRangeExpression"},{"range":[{"introduced":"3.4.0"},{"fixed":"3.4.14"}],"source":"AFFECTED_FIELD","strategy":"StringRangeExpression"},{"source":"REFERENCES_COMMIT","range":[{"fixed":"0efec58d2d28a0ee322f5028dee6fb57d459580e"}]},{"range":[{"fixed":"78e91146fceeee317820a146ba99a96f380945b8"}],"source":"REFERENCES_COMMIT"},{"range":[{"fixed":"f0e404f7298cd8563a1d30a64a1c982dbd68fc49"}],"source":"REFERENCES_COMMIT"}]}}],"versions":["v3.4.13-rc3","v3.4.13","v3.3.12-rc","v3.3.12","v3.2.10-rc","v3.2.10","v3.2.9-rc","v3.2.9","v3.3.11-rc3","v3.3.11","v3.4.13-rc2","v3.4.13-rc","v3.4.12","v3.4.12-rc2","v3.4.11-rc3","v3.4.11","v3.4.11-rc2","v3.4.11-rc","v3.4.10-rc","v3.4.10","v3.3.10-rc2","v3.3.10","v3.2.8-rc","v3.2.8","v3.3.10-rc","v3.2.7-rc","v3.2.7","v3.3.9-rc2","v3.3.9","v3.4.9","v3.3.9-rc","v3.2.6-rc","v3.2.6","v3.3.8-rc","v3.3.8","v3.4.9-rc","v3.4.8-rc","v3.4.8","v3.4.7","v3.4.7-rc","v3.4.6","v3.4.6-rc","v3.2.5-rc","v3.2.5","v3.3.7-rc4","v3.3.7","v3.4.5","v3.4.5-rc","v3.3.7-rc3","v3.3.7-rc2","v3.3.7-rc","v3.3.6","v3.4.4-rc2","v3.4.4","v3.4.4-rc","v3.4.3-rc3","v3.4.3","v3.3.6-rc4","v3.3.6-rc3","v3.4.3-rc2","v3.2.4-rc2","v3.2.4","v3.3.6-rc2","v3.4.3-rc","v3.3.6-rc","v3.3.5","v3.4.2-rc2","v3.4.2","v3.4.2-rc","v3.4.1-rc2","v3.4.1","v3.4.1-rc","v3.4.0","v3.3.5-rc3","v3.3.5-rc","v3.3.4-rc","v3.3.4","v3.3.3-rc1","v3.3.3","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","v3.2.4-rc","v3.2.3-rc2","v3.2.3","v3.2.3-rc","v3.2.2","v3.2.2-rc2","v3.2.2-rc","v3.2.1-rc","v3.2.1","v3.2.0-rc4","v3.2.0","v3.2.0-rc3","v3.2.0-rc2","v3.2.0-rc","v3.0.0-beta","v2.5.0","v2.4.0","v2.4.0-beta.1","v2.3.0","v2.1.0","v2.0.1","v2.0.0.GM","v2.0.0","v1.7.1","OPENEXR_1_0_4"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-59983.json","vanir_signatures":[{"digest":{"function_hash":"339408909512260573092273825431912123811","length":1534},"id":"CVE-2026-59983-6e265ebe","signature_type":"Function","signature_version":"v1","source":"https://github.com/academysoftwarefoundation/openexr/commit/78e91146fceeee317820a146ba99a96f380945b8","target":{"file":"src/lib/OpenEXRCore/decoding.c","function":"update_pack_unpack_ptrs"},"deprecated":false},{"id":"CVE-2026-59983-87d130e2","signature_type":"Line","signature_version":"v1","source":"https://github.com/academysoftwarefoundation/openexr/commit/0efec58d2d28a0ee322f5028dee6fb57d459580e","target":{"file":"src/lib/OpenEXRCore/decoding.c"},"deprecated":false,"digest":{"threshold":0.9,"line_hashes":["338149736148742830300084897856731932702","183122052018604722738171854198928537985","178106560355941550759265943021031180573","164868186857540652901670056307331008853","328528351640039101856825666883211199849","26917533211081568291890224810403432545","210149596594307807756661450506056727661","185730338530026942004507408900026126760"]}},{"deprecated":false,"digest":{"line_hashes":["338149736148742830300084897856731932702","183122052018604722738171854198928537985","178106560355941550759265943021031180573","1648681
