It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-68515 exists.\n\nAffected product: AcademySoftwareFoundation openexr. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-68515/ (Markdown: https://insights.sbomify.com/CVE-2026-68515/index.md)","id":"CVE-2026-68515","markdown":"https://insights.sbomify.com/CVE-2026-68515/index.md","name":"CVE-2026-68515","record":{"aliases":["ALSA-2026:69608","ALSA-2026:69609","AZL-97646","BELL-CVE-2026-68515","CLSA-2026-1790780350","CLSA-2026-1790781324","DEBIAN-CVE-2026-68515","ECHO-4a45-30ec-eef0","GHSA-gjf7-wjjw-xq56","MINI-3wvr-x389-vx58","RHSA-2026:69608","RHSA-2026:69609","RLSA-2026:69608","RLSA-2026:69609","ROOT-OS-DEBIAN-11-CVE-2026-68515","ROOT-OS-DEBIAN-12-CVE-2026-68515","ROOT-OS-DEBIAN-13-CVE-2026-68515","UBUNTU-CVE-2026-68515"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OpenEXR image library","requires_auth":"none","summary":"Attacker can trigger heap out-of-bounds write in exrmultiview by providing crafted EXR files, potentially leading to code execution or crashes.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"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.","ecosystems":["AlmaLinux:10","AlmaLinux:9","Red Hat:enterprise_linux:10.2","Red Hat:enterprise_linux:9::appstream","Red
