{"id":"DEBIAN-CVE-2026-42450","details":"OpenColorIO is a color management framework for visual effects and animation. Prior to version 2.5.2, `FileFormatSpi3D.cpp:163` uses `sscanf` with `%s` into 64-byte stack buffers when parsing LUT data lines. Input comes from `lineBuffer[4096]`, so a crafted .spi3d file can overflow by ~4000 bytes on non-Windows. Version 2.5.2 fixes the issue.","modified":"2026-09-14T17:03:34.087989276Z","published":"2026-06-24T14:17:31.190Z","upstream":["CVE-2026-42450"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-42450"}],"affected":[{"package":{"name":"opencolorio","ecosystem":"Debian:12","purl":"pkg:deb/debian/opencolorio?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.1.2+dfsg1-4","2.1.2+dfsg1-4.1","2.1.2+dfsg1-4.2","2.1.3+dfsg-1","2.1.3+dfsg-1.1","2.1.3+dfsg-1.1+loong64","2.1.3+dfsg-1.1~exp1","2.1.3+dfsg-1.2","2.1.3+dfsg-2","2.5.1+dfsg-1","2.5.1+dfsg-2","2.5.1+dfsg-3","2.5.1+dfsg-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-42450.json"}},{"package":{"name":"opencolorio","ecosystem":"Debian:13","purl":"pkg:deb/debian/opencolorio?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.1.3+dfsg-1.2","2.1.3+dfsg-2","2.5.1+dfsg-1","2.5.1+dfsg-2","2.5.1+dfsg-3","2.5.1+dfsg-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-42450.json"}},{"package":{"name":"opencolorio","ecosystem":"Debian:14","purl":"pkg:deb/debian/opencolorio?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.1.3+dfsg-1.2","2.1.3+dfsg-2","2.5.1+dfsg-1","2.5.1+dfsg-2","2.5.1+dfsg-3","2.5.1+dfsg-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-42450.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
