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-2021-1143/ (Markdown: https://insights.sbomify.com/OSV-2021-1143/index.md)","id":"OSV-2021-1143","markdown":"https://insights.sbomify.com/OSV-2021-1143/index.md","name":"OSV-2021-1143","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"unknown","non_default_config":false,"product_category":"Qt graphics library","requires_auth":"none","summary":"A memory corruption vulnerability in the Qt library's QPainterPath handling can lead to application crashes when processing malformed data.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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=37306\n\nThis is the same issue as OSV-2021-1121 which it replaced after that one was closed wrongly.\n\n```\nCrash type: UNKNOWN WRITE\nCrash state:\nQtPrivate::QPodArrayOps\u003cQPainterPath::Element\u003e::copyAppend\nQtPrivate::QCommonArrayOps\u003cQPainterPath::Element\u003e::growAppend\nQList\u003cQPainterPath::Element\u003e::append\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":"UNKNOWN WRITE in QtPrivate::QPodArrayOps\u003cQPainterPath::Element\u003e::copyAppend","id":"OSV-2021-1143","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"OSS-Fuzz","product":null,"products":[],"type":"memory_corruption","year":"2021"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"OSS-Fuzz","fixed":[],"introduced":[],"last_affected":[],"package":"qt","purl":"pkg:generic/qt","source":"OSV-2021-1143"}],"products":null,"published":"2021-08-19","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":"A memory corruption vulnerability in the Qt library's QPainterPath handling can lead to application crashes when processing malformed data.","url":"https://insights.sbomify.com/OSV-2021-1143/"}
