It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2019-11463 and fix it if it is affected.\n\nWhat it is: CVE-2019-11463 is a medium-severity denial of service vulnerability in Libarchive Libarchive, published on 23 Apr 2019. 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 CVE-2019-11463 in the wild and no public exploit code.\n\nAffected product: Libarchive Libarchive. 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-2019-11463/ (Markdown: https://insights.sbomify.com/CVE-2019-11463/index.md)","id":"CVE-2019-11463","markdown":"https://insights.sbomify.com/CVE-2019-11463/index.md","name":"CVE-2019-11463","record":{"aliases":["GHSA-v36x-fh5g-gvf8"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"libarchive library","requires_auth":"none","summary":"Remote attackers can cause denial of service via crafted ZIP files due to a memory leak in specific development builds of libarchive.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libarchive","vendor":"libarchive"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"A memory leak in archive_read_format_zip_cleanup in archive_read_support_format_zip.c in libarchive 3.3.4-dev allows remote attackers to cause a denial of service via a crafted ZIP file because of a HAVE_LZMA_H typo.
