{"id":"UBUNTU-CVE-2026-59156","details":"OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.20.0, 3.1.15.0, and 3.2.0.3-beta1, A crafted fits stream containing consecutive 2880-byte header blocks without the mandatory end keyword makes fitsinput::read_fits_header() call itself without a depth bound. repeated recursive parsing exhausts the application stack, resulting in denial of service. The affected implementation is identified by src/fits.imageio/fitsinput.cpp, FitsInput::read_fits_header(), END keyword, and 2880-byte FITS header blocks, which define the relevant source path, functions, state, and trigger. This issue is fixed in versions 3.0.20.0, 3.1.15.0, and 3.2.0.3-beta1.","modified":"2026-09-21T21:39:52.044260354Z","published":"2026-09-21T00:00:00Z","upstream":["CVE-2026-59156"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-59156"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-59156"},{"type":"REPORT","url":"https://github.com/AcademySoftwareFoundation/OpenImageIO/security/advisories/GHSA-xvwr-x6ch-v2fq"},{"type":"REPORT","url":"https://github.com/AcademySoftwareFoundation/OpenImageIO/pull/5248"},{"type":"REPORT","url":"https://github.com/AcademySoftwareFoundation/OpenImageIO/commit/b0de7d40d06eb4abc7ef14c1321a1a2a976d8c1c"},{"type":"REPORT","url":"https://github.com/AcademySoftwareFoundation/OpenImageIO/commit/b0de7d40d06eb4abc7ef14c1321a1a2a976d8c1c"},{"type":"REPORT","url":"https://github.com/AcademySoftwareFoundation/OpenImageIO/releases/tag/v3.0.20.0"},{"type":"REPORT","url":"https://github.com/AcademySoftwareFoundation/OpenImageIO/releases/tag/v3.1.15.0"}],"affected":[{"package":{"name":"openimageio","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/openimageio?arch=source&distro=esm-apps-legacy%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.5.17~dfsg0-1ubuntu2","1.5.20~dfsg0-1ubuntu2","1.5.23~dfsg0-1ubuntu1","1.6.9~dfsg0-4ubuntu1","1.6.10~dfsg0-1ubuntu1","1.6.10~dfsg0-2ubuntu1","1.6.11~dfsg0-1ubuntu1","1.6.11~dfsg0-1ubuntu1+esm2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.6.11~dfsg0-1ubuntu1+esm2","binary_name":"libopenimageio1.6"},{"binary_name":"openimageio-tools","binary_version":"1.6.11~dfsg0-1ubuntu1+esm2"},{"binary_version":"1.6.11~dfsg0-1ubuntu1+esm2","binary_name":"python-openimageio"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-59156.json"}},{"package":{"name":"openimageio","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/openimageio?arch=source&distro=esm-apps%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.6.17~dfsg0-1ubuntu5","1.7.17~dfsg0-1ubuntu2","1.7.17~dfsg0-1ubuntu2+esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"libopenimageio1.7","binary_version":"1.7.17~dfsg0-1ubuntu2+esm1"},{"binary_name":"openimageio-tools","binary_version":"1.7.17~dfsg0-1ubuntu2+esm1"},{"binary_version":"1.7.17~dfsg0-1ubuntu2+esm1","binary_name":"python-openimageio"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-59156.json"}},{"package":{"name":"openimageio","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/openimageio?arch=source&distro=esm-apps%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.0.10~dfsg0-1","2.0.11~dfsg0-1","2.0.12~dfsg0-1","2.0.12~dfsg0-1build1","2.0.12~dfsg0-1build2","2.1.10.1~dfsg0-5ubuntu4","2.1.10.1~dfsg0-5ubuntu5","2.1.12.0~dfsg0-1","2.1.12.0~dfsg0-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"libopenimageio2.1","binary_version":"2.1.12.0~dfsg0-1ubuntu0.1~esm1"},{"binary_name":"openimageio-tools","binary_version":"2.1.12.0~dfsg0-1ubuntu0.1~esm1"},{"binary_name":"python3-openimageio","binary_version":"2.1.12.0~dfsg0-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-59156.json"}},{"package":{"name":"openimageio","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/openimageio?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.2.10.1+dfsg-1build1","2.2.18.0+dfsg-1","2.2.18.0+dfsg-1build2","2.2.18.0+dfsg-1ubuntu2"],"ecosystem_specific":{"binaries":[{"binary_name":"libopenimageio2.2","binary_version":"2.2.18.0+dfsg-1ubuntu2"},{"binary_version":"2.2.18.0+dfsg-1ubuntu2","binary_name":"openimageio-tools"},{"binary_name":"python3-openimageio","binary_version":"2.2.18.0+dfsg-1ubuntu2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-59156.json"}},{"package":{"name":"openimageio","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/openimageio?arch=source&distro=esm-apps%2Fnoble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4.14.0+dfsg-1","2.4.16.0+dfsg-1","2.4.16.0+dfsg-1build1","2.4.17.0+dfsg-1","2.4.17.0+dfsg-1build1","2.4.17.0+dfsg-1.1build3","2.4.17.0+dfsg-1.1build4","2.4.17.0+dfsg-1.1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"libopenimageio2.4t64","binary_version":"2.4.17.0+dfsg-1.1ubuntu0.1~esm1"},{"binary_name":"openimageio-tools","binary_version":"2.4.17.0+dfsg-1.1ubuntu0.1~esm1"},{"binary_version":"2.4.17.0+dfsg-1.1ubuntu0.1~esm1","binary_name":"python3-openimageio"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-59156.json"}},{"package":{"name":"openimageio","ecosystem":"Ubuntu:Pro:26.04:LTS"
