An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-17543 in the wild and no public exploit code.\n\nAffected product: n/a. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2019-17543/ (Markdown: https://insights.sbomify.com/CVE-2019-17543/index.md)","id":"CVE-2019-17543","markdown":"https://insights.sbomify.com/CVE-2019-17543/index.md","name":"CVE-2019-17543","record":{"aliases":["ALPINE-CVE-2019-17543","ALSA-2025:11035","DEBIAN-CVE-2019-17543","GHSA-fxrv-74g3-w7qr","MGASA-2019-0375","RHSA-2025:11035","RLSA-2025:11035","SUSE-SU-2019:2757-1","openSUSE-SU-2019:2398-1","openSUSE-SU-2019:2399-1","openSUSE-SU-2024:11034-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"LZ4 compression library","requires_auth":"none","summary":"Heap-based buffer overflow in LZ4 library allows attackers to execute arbitrary code or cause denial of service via large inputs.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"lz4","vendor":"lz4_project"}],"cvss":{"score":8.1,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"LZ4 before 1.9.2 has a heap-based buffer overflow in LZ4_write32 (related to LZ4_compress_destSize), affecting applications that call LZ4_compress_fast with a large input.
