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-2025-48074 exists.\n\nAffected packages and fixed versions:\n- openexr (PyPI): affected from 3.3.2; fixed in 3.3.3\n- openexr (PyPI): affected from 3.3.2; fixed in 3.3.3\n- OpenEXR (PyPI): affected from 3.3.2; fixed in 3.3.3\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-2025-48074/ (Markdown: https://insights.sbomify.com/CVE-2025-48074/index.md)","id":"CVE-2025-48074","markdown":"https://insights.sbomify.com/CVE-2025-48074/index.md","name":"CVE-2025-48074","record":{"aliases":["DEBIAN-CVE-2025-48074","GHSA-x22w-82jp-8rvf","PYSEC-2026-1749","ROOT-OS-DEBIAN-11-CVE-2025-48074","ROOT-OS-DEBIAN-12-CVE-2025-48074","ROOT-OS-DEBIAN-13-CVE-2025-48074"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OpenEXR image library","requires_auth":"none","summary":"Attackers can cause out-of-memory errors and performance degradation by providing malicious EXR files with unvalidated header values.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"openexr","vendor":"openexr"}],"cvss":{"score":4.6,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"OpenEXR provides the specification and reference implementation of the EXR file format, an image storage format for the motion picture industry.
