An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of OSV-2021-586 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- kimageformats (OSS-Fuzz): affected all versions; no fix listed\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/OSV-2021-586/ (Markdown: https://insights.sbomify.com/OSV-2021-586/index.md)","id":"OSV-2021-586","markdown":"https://insights.sbomify.com/OSV-2021-586/index.md","name":"OSV-2021-586","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"AV1 decoder library","requires_auth":"none","summary":"An attacker can trigger a use-of-uninitialized-value bug in the AV1 decoder, potentially leading to information disclosure.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"OSS-Fuzz report: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=32682\n\n```\nCrash type: Use-of-uninitialized-value\nCrash state:\nvoid intra_prediction_angular\u003cunsigned short\u003e\nvoid decode_intra_prediction_internal\u003cunsigned short\u003e\ndecode_intra_prediction\n```","ecosystems":["OSS-Fuzz"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Use-of-uninitialized-value in void intra_prediction_angular\u003cunsigned short\u003e","id":"OSV-2021-586","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"OSS-Fuzz","product":null,"products":[],"type":"information_disclosure","year":"2021"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"OSS-Fuzz","fixed":[],"introduced":[],"last_affected":[],"package":"kimageformats","purl":"pkg:generic/kimageformats","source":"OSV-2021-586"}],"products":null,"published":"2021-03-31","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"OSS-Fuzz","prefix":"OSV"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"An attacker can trigger a use-of-uninitialized-value bug in the AV1 decoder, potentially leading to information disclosure.","url":"https://insights.sbomify.com/OSV-2021-586/"}
