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-2021-1684/ (Markdown: https://insights.sbomify.com/OSV-2021-1684/index.md)","id":"OSV-2021-1684","markdown":"https://insights.sbomify.com/OSV-2021-1684/index.md","name":"OSV-2021-1684","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"unknown","non_default_config":false,"product_category":"PDF parsing library","requires_auth":"none","summary":"A memory read error in the PDF parsing library can cause a crash when processing malformed files, requiring user interaction to open the 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=42285\n\n```\nCrash type: UNKNOWN READ\nCrash state:\npdfi_open_memory_stream_from_filtered_stream\npdfi_create_iccbased\npdfi_create_colorspace_by_array\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 READ in pdfi_open_memory_stream_from_filtered_stream","id":"OSV-2021-1684","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":"ghostscript","purl":"pkg:generic/ghostscript","source":"OSV-2021-1684"}],"products":null,"published":"2021-12-14","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 read error in the PDF parsing library can cause a crash when processing malformed files, requiring user interaction to open the file.","url":"https://insights.sbomify.com/OSV-2021-1684/"}
