{"id":"UBUNTU-CVE-2026-59183","details":"OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. In versions 3.1.0 through 3.2.10, 3.3.0 through 3.3.12, and 3.4.0 through 3.4.13, an int32_t multiplication in OpenEXRCore's unpack_sample_table() can overflow while decoding a crafted deep tiled EXR file, producing an invalid pointer that leads to a read from an unmapped memory address and a crash. Because the overflow occurs in the standard decoding path (exr_decoding_run), any application that decodes deep tiled EXR files is affected. This issue is fixed in versions 3.2.11, 3.3.13, and 3.4.14.","modified":"2026-09-02T16:20:03Z","published":"2026-08-25T01:16:00Z","upstream":["CVE-2026-59183"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-59183"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-59183"},{"type":"REPORT","url":"https://github.com/academysoftwarefoundation/openexr/commit/5e55a64ad1f119a8166542f4b6e034c31b7e043a"},{"type":"REPORT","url":"https://github.com/academysoftwarefoundation/openexr/commit/a6cf183725b5665ac3fdbec640125fba5ee1ab39"},{"type":"REPORT","url":"https://github.com/academysoftwarefoundation/openexr/commit/e2adb5be3bbc3a1f82f2bc06cc9699995a99a607"},{"type":"REPORT","url":"https://github.com/academysoftwarefoundation/openexr/security/advisories/ghsa-rqp5-pmwm-wj6x"},{"type":"REPORT","url":"https://github.com/cveproject/cvelistv5/tree/main/cves/2026/59xxx/cve-2026-59183.json"},{"type":"REPORT","url":"https://nvd.nist.gov/vuln/detail/cve-2026-59183"}],"affected":[{"package":{"name":"openexr","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/openexr?arch=source&distro=esm-infra%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.2.0-1ubuntu3","2.2.0-7ubuntu1","2.2.0-9ubuntu1","2.2.0-10ubuntu2","2.2.0-10ubuntu2.1","2.2.0-10ubuntu2.2","2.2.0-10ubuntu2.3","2.2.0-10ubuntu2.4","2.2.0-10ubuntu2.6","2.2.0-10ubuntu2.6+esm1","2.2.0-10ubuntu2.6+esm2","2.2.0-10ubuntu2.6+esm3","2.2.0-10ubuntu2.6+esm4"],"ecosystem_specific":{"binaries":[{"binary_name":"libopenexr22","binary_version":"2.2.0-10ubuntu2.6+esm4"},{"binary_name":"openexr","binary_version":"2.2.0-10ubuntu2.6+esm4"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-59183.json"}},{"package":{"name":"openexr","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/openexr?arch=source&distro=esm-infra%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.2.0-11ubuntu1","2.2.0-11.1ubuntu1","2.2.0-11.1ubuntu1.1","2.2.0-11.1ubuntu1.2","2.2.0-11.1ubuntu1.3","2.2.0-11.1ubuntu1.4","2.2.0-11.1ubuntu1.6","2.2.0-11.1ubuntu1.7","2.2.0-11.1ubuntu1.8","2.2.0-11.1ubuntu1.9","2.2.0-11.1ubuntu1.9+esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"libopenexr22","binary_version":"2.2.0-11.1ubuntu1.9+esm1"},{"binary_name":"openexr","binary_version":"2.2.0-11.1ubuntu1.9+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-59183.json"}},{"package":{"name":"openexr","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/openexr?arch=source&distro=esm-apps%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.2.1-4.1ubuntu1","2.3.0-6","2.3.0-6build1","2.3.0-6ubuntu0.1","2.3.0-6ubuntu0.2","2.3.0-6ubuntu0.3","2.3.0-6ubuntu0.5","2.3.0-6ubuntu0.5+esm1","2.3.0-6ubuntu0.5+esm2"],"ecosystem_specific":{"binaries":[{"binary_version":"2.3.0-6ubuntu0.5+esm2","binary_name":"libopenexr24"},{"binary_name":"openexr","binary_version":"2.3.0-6ubuntu0.5+esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-59183.json"}},{"package":{"name":"openexr","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/openexr?arch=source&distro=esm-apps%2Fjammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.5.4-2","2.5.7-1","2.5.7-1ubuntu0.1~esm1","2.5.7-1ubuntu0.1~esm2"],"ecosystem_specific":{"binaries":[{"binary_name":"libopenexr25","binary_version":"2.5.7-1ubuntu0.1~esm2"},{"binary_name":"openexr","binary_version":"2.5.7-1ubuntu0.1~esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-59183.json"}},{"package":{"name":"openexr","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/openexr?arch=source&distro=esm-apps%2Fnoble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.5-5.1","3.1.5-5.1build1","3.1.5-5.1build2","3.1.5-5.1build3","3.1.5-5.1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"3.1.5-5.1ubuntu0.1~esm1","binary_name":"libopenexr-3-1-30"},{"binary_name":"openexr","binary_version":"3.1.5-5.1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-59183.json"}},{"package":{"name":"openexr","ecosystem":"Ubuntu:Pro:26.04:LTS","purl":"pkg:deb/ubuntu/openexr?arch=source&distro=esm-apps%2Fresolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.13-2","3.1.13-2build1","3.1.13-2ubuntu0.26.04.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"libopenexr-3-1-30","binary_version":"3.1.13-2ubuntu0.26.04.1~esm1"},{"binary_name":"openexr","binary_version":"3.1.13-2ubuntu0.26.04.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNT
