Prior to 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1, A valid tiled openexr image whose width is not a multiple of its tile width can trigger an overflow when a caller reads a partial edge-tile rectangle. openexrinput::read_native_tiles() copies each row into the caller buffer using the padded whole-tile scanline_stride rather than user_scanline_bytes for the requested rectangle, resulting in a heap out-of-bounds write and memory corruption. The affected implementation is identified by src/openexr.imageio/exrinput.cpp, OpenEXRInput::read_native_tiles(), partial edge tile, user_scanline_bytes, and scanline_stride, 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."}], "lastModified": "2026-09-29T18:56:15.287", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:openimageio:openimageio:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "58BCF458-A0CC-4E42-B8DC-DA0F17FB9526", "versionEndExcluding": "3.0.21.0"}, {"criteria": "cpe:2.3:a:openimageio:openimageio:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "1BF66CB3-6DE8-41F1-98DF-16E17968F4F0", "versionEndIncluding": "3.1.16.0", "versionStartIncluding": "3.1.0.0"}, {"criteria": "cpe:2.3:a:openimageio:openimageio:3.2.0.0:dev:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "F43FE0AC-4CFC-485D-8370-37336EB2CEA0"}, {"criteria": "cpe:2.3:a:openimageio:openimageio:3.2.0.2:dev:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "450296D8-74F5-4847-8433-FE3DFB16C58E"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
