{"id":"DEBIAN-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":"2026-09-25T08:47:29.357107080Z","published":"2026-09-18T16:17:06.980Z","upstream":["CVE-2026-59156"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-59156"}],"affected":[{"package":{"name":"openimageio","ecosystem":"Debian:12","purl":"pkg:deb/debian/openimageio?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4.12.0+dfsg-1","2.4.13.0+dfsg-1","2.4.14.0+dfsg-1","2.4.16.0+dfsg-1","2.4.17.0+dfsg-1","2.4.17.0+dfsg-1.1","2.4.7.1+dfsg-2","2.4.9.0+dfsg-1","2.5.10.1+dfsg-1","2.5.12.0+dfsg-1","2.5.12.0+dfsg-2","2.5.14.0+dfsg-1","2.5.15.0+dfsg-1","2.5.16.0+dfsg-1","2.5.18.0+dfsg-1","2.5.19.1+dfsg-1","2.5.19.1+dfsg-2","2.5.7.0+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-59156.json"}},{"package":{"name":"openimageio","ecosystem":"Debian:13","purl":"pkg:deb/debian/openimageio?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.5.18.0+dfsg-1","2.5.19.1+dfsg-1","2.5.19.1+dfsg-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-59156.json"}},{"package":{"name":"openimageio","ecosystem":"Debian:14","purl":"pkg:deb/debian/openimageio?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.5.18.0+dfsg-1","2.5.19.1+dfsg-1","2.5.19.1+dfsg-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-59156.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
