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: There is no known exploitation of OSV-2022-656 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- libredwg (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-2022-656/ (Markdown: https://insights.sbomify.com/OSV-2022-656/index.md)","id":"OSV-2022-656","markdown":"https://insights.sbomify.com/OSV-2022-656/index.md","name":"OSV-2022-656","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"DWG parsing library","requires_auth":"none","summary":"A heap-buffer-overflow in the DWG decoder allows attackers to cause crashes or potentially execute code by providing a malicious DWG file.","user_interaction":"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=49630\n\n```\nCrash type: Heap-buffer-overflow READ 1\nCrash state:\ndwg_decode_LWPOLYLINE_private\ndwg_decode_LWPOLYLINE\ndwg_decode_add_object\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":"Heap-buffer-overflow in dwg_decode_LWPOLYLINE_private","id":"OSV-2022-656","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"OSS-Fuzz","product":null,"products":[],"type":"memory_corruption","year":"2022"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"OSS-Fuzz","fixed":[],"introduced":[],"last_affected":[],"package":"libredwg","purl":"pkg:generic/libredwg","source":"OSV-2022-656"}],"products":null,"published":"2022-07-31","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":"A heap-buffer-overflow in the DWG decoder allows attackers to cause crashes or potentially execute code by providing a malicious DWG file.","url":"https://insights.sbomify.com/OSV-2022-656/"}
