{"id":"DEBIAN-CVE-2026-65969","details":"OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1, A truncated tga can leave a pending gif frame that is processed during output close. gifsplitpalette() computes numpixels multiplied by the palette partition width in signed 32-bit arithmetic; a large image overflows that intermediate, corrupts subpixelsa, and drives an out-of-bounds read while building the gif palette, resulting in a process crash and denial of service. The affected implementation is identified by src/gif.imageio/gif.h, GifSplitPalette(), numPixels, subPixelsA, GIFOutput, and truncated TGA input, which define the relevant source path, functions, state, and trigger. This issue is fixed in versions 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1.","modified":"2026-09-24T08:47:26.378948916Z","published":"2026-09-18T16:17:08.433Z","upstream":["CVE-2026-65969"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-65969"}],"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-2026-65969.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-2026-65969.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-2026-65969.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"}]}
