{"id":"DEBIAN-CVE-2026-50291","details":"OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to versions 3.0.16.0 and 3.1.11.0, processing a crafted BMP file through oiiotool or an application linked to OpenImageIO can reach BMP palette handling in src/bmp.imageio/bmpinput.cpp with an empty color table. BmpInput::read_native_scanline then performs an invalid palette read while decoding an RLE-compressed scanline, causing a process crash and denial of service. This issue is fixed in versions 3.0.16.0 and 3.1.11.0.","modified":"2026-09-25T08:47:27.054953279Z","published":"2026-09-17T22:16:59.450Z","upstream":["CVE-2026-50291"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-50291"}],"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-2026-50291.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-2026-50291.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-2026-50291.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
