{"cve":"CVE-2026-68515","nvd":{"published":"2026-08-25T20:17:02.780","modified":"2026-09-09T21:07:31.353","status":"Deferred","description":"OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. In versions before 3.2.11, 3.3.0 through 3.3.12, and 3.4.0 through 3.4.13, exrmultiview can write past a heap allocation when it combines two attacker-supplied, individually valid scanline EXR files whose union dataWindow is not aligned to one view's channel subsampling. The utility allocates sampled channel storage using a truncated union_width / xSampling, then reads the sampled input through a Slice based on the misaligned union window, producing a heap out-of-bounds write. The trigger is normal public-tool processing, such as exrmultiview left A.exr right B.exr out.exr with crafted but valid inputs, so this is not solely an API or caller-precondition issue. This issue is fixed in versions 3.2.11, 3.3.13, and 3.4.14.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H","score":7.1},"cwes":["CWE-122","CWE-787"],"references":["https://github.com/AcademySoftwareFoundation/openexr/commit/77ee19c021398b1c56f32c3af8347e365dbd4f33","https://github.com/AcademySoftwareFoundation/openexr/commit/c644ac2dfeac82939c81a8551d6f4b7859f63add","https://github.com/AcademySoftwareFoundation/openexr/commit/e2300a3d54a93d20a36a86b82f3a506c4c91476f","https://github.com/AcademySoftwareFoundation/openexr/security/advisories/GHSA-gjf7-wjjw-xq56","https://github.com/AcademySoftwareFoundation/openexr/security/advisories/GHSA-gjf7-wjjw-xq56"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:17.453294893+00:00"},"epss":{"cve":"CVE-2026-68515","score":0.00191,"percentile":0.08774,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
