{"id":"UBUNTU-CVE-2026-42217","details":"OpenEXR provides the specification and reference implementation of the EXR file format, an image storage format for the motion picture industry. From versions 3.0.0 to before 3.2.9, 3.3.0 to before 3.3.11, and 3.4.0 to before 3.4.11, readVariableLengthInteger() decodes a variable-length integer from untrusted EXR input without bounding the shift count. After enough continuation bytes, the code executes a left shift by 70 on a 64-bit value, which is undefined behavior. This issue has been patched in versions 3.2.9, 3.3.11, and 3.4.11.","modified":"2026-05-14T14:44:48.814359Z","published":"2026-05-07T04:16:00Z","upstream":["CVE-2026-42217"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-42217"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-42217"},{"type":"REPORT","url":"https://github.com/AcademySoftwareFoundation/openexr/security/advisories/GHSA-3c67-4wwp-w52m"},{"type":"REPORT","url":"https://github.com/AcademySoftwareFoundation/openexr/pull/2378"}],"affected":[{"package":{"name":"openexr","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/openexr@2.2.0-10ubuntu2.6+esm4?arch=source&distro=esm-infra/xenial"},"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-2026-42217.json"}},{"package":{"name":"openexr","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/openexr@2.2.0-11.1ubuntu1.9+esm1?arch=source&distro=esm-infra/bionic"},"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-2026-42217.json"}},{"package":{"name":"openexr","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/openexr@2.3.0-6ubuntu0.5+esm2?arch=source&distro=esm-apps/focal"},"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_name":"libopenexr24","binary_version":"2.3.0-6ubuntu0.5+esm2"},{"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-2026-42217.json"}},{"package":{"name":"openexr","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/openexr@2.5.7-1ubuntu0.1~esm2?arch=source&distro=esm-apps/jammy"},"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-2026-42217.json"}},{"package":{"name":"openexr","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/openexr@3.1.5-5.1ubuntu0.1~esm1?arch=source&distro=esm-apps/noble"},"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_name":"libopenexr-3-1-30","binary_version":"3.1.5-5.1ubuntu0.1~esm1"},{"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-2026-42217.json"}},{"package":{"name":"openexr","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/openexr@3.1.13-2?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.13-2"],"ecosystem_specific":{"binaries":[{"binary_name":"libopenexr-3-1-30","binary_version":"3.1.13-2"},{"binary_name":"openexr","binary_version":"3.1.13-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-42217.json"}},{"package":{"name":"openexr","ecosystem":"Ubuntu:Pro:26.04:LTS","purl":"pkg:deb/ubuntu/openexr@3.1.13-2ubuntu0.26.04.1~esm1?arch=source&distro=esm-apps/resolute"},"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
