It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-3171 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- com.google.protobuf:protobuf-java (Maven): affected all versions; fixed in 3.16.3\n- com.google.protobuf:protobuf-java (Maven): affected all versions; fixed in 3.16.3\n- com.google.protobuf:protobuf-java (Maven): affected from 3.17.0-rc-1; fixed in 3.19.6\n- com.google.protobuf:protobuf-java (Maven): affected from 3.17.0-rc-1; fixed in 3.19.6\n- com.google.protobuf:protobuf-java (Maven): affected from 3.20.0-rc-1; fixed in 3.20.3\n- com.google.protobuf:protobuf-java (Maven): affected from 3.20.0-rc-1; fixed in 3.20.3\n- com.google.protobuf:protobuf-java (Maven): affected from 3.21.0-rc-1; fixed in 3.21.7\n- com.google.protobuf:protobuf-java (Maven): affected from 3.21.0-rc-1; fixed in 3.21.7\n- com.google.protobuf:protobuf-javalite (Maven): affected all versions; fixed in 3.16.3\n- com.google.protobuf:protobuf-javalite (Maven): affected all versions; fixed in 3.16.3\n- com.google.protobuf:protobuf-javalite (Maven): affected from 3.17.0-rc-1; fixed in 3.19.6\n- com.google.protobuf:protobuf-javalite (Maven): affected from 3.17.0-rc-1; fixed in 3.19.6\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-2022-3171/ (Markdown: https://insights.sbomify.com/CVE-2022-3171/index.md)","id":"CVE-2022-3171","markdown":"https://insights.sbomify.com/CVE-2022-3171/index.md","name":"CVE-2022-3171","record":{"aliases":["CLEANSTART-2026-AV57631","CLEANSTART-2026-FD57145","DEBIAN-CVE-2022-3171","ECHO-7811-b7c6-2509","GHSA-h4h5-3hr4-j3g2","MINI-243g-q5cw-w5hf","MINI-4hx4-f29f-96cg","MINI-7243-5mx4-g3m9","MINI-79rm-h588-f854","MINI-98v7-cwqp-44m2","ROOT-APP-MAVEN-CVE-2022-3171","UBUNTU-CVE-2022-3171"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Java Protocol Buffers library","requires_auth":"none","summary":"Attackers can cause denial of service via long garbage collection pauses by sending crafted binary data to applications using the Protocol Buffers Java library.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Google","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"google-protobuf","vendor":"google"},{"product":"protobuf-java","vendor":"google"},{"product":"protobuf-javalite","vendor":"google"},{"product":"protobuf-kotlin","vendor":"google"},{"product":"protobuf-kotlin-lite","vendor":"google"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A parsing issue with binary data in protobuf-java core and lite versions prior to 3.21.7, 3.20.3, 3.19.6 and 3.16.3 can lead to a denial of service attack.
