{"id":"CVE-2026-65969","published":"2026-09-18T16:17:08.433","lastModified":"2026-09-23T18:12:04.247","description":"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.","cvssScore":5.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","cwes":["CWE-125","CWE-190"],"vendors":[],"products":[],"references":[{"url":"https://github.com/AcademySoftwareFoundation/OpenImageIO/commit/134977da625a84fc5a09a34321806f1fe0093c24","tags":[]},{"url":"https://github.com/AcademySoftwareFoundation/OpenImageIO/pull/5292","tags":[]},{"url":"https://github.com/AcademySoftwareFoundation/OpenImageIO/releases/tag/v3.0.21.0","tags":[]},{"url":"https://github.com/AcademySoftwareFoundation/OpenImageIO/releases/tag/v3.1.16.0","tags":[]},{"url":"https://github.com/AcademySoftwareFoundation/OpenImageIO/security/advisories/GHSA-9mwc-fjgj-8wmq","tags":[]}],"exploitRefs":[{"url":"https://github.com/AcademySoftwareFoundation/OpenImageIO/commit/134977da625a84fc5a09a34321806f1fe0093c24","tags":[]},{"url":"https://github.com/AcademySoftwareFoundation/OpenImageIO/pull/5292","tags":[]},{"url":"https://github.com/AcademySoftwareFoundation/OpenImageIO/releases/tag/v3.0.21.0","tags":[]},{"url":"https://github.com/AcademySoftwareFoundation/OpenImageIO/releases/tag/v3.1.16.0","tags":[]},{"url":"https://github.com/AcademySoftwareFoundation/OpenImageIO/security/advisories/GHSA-9mwc-fjgj-8wmq","tags":[]}],"hasPoc":true,"ai":null}
