An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2019-5020 in the wild and no public exploit code.\n\nAffected product: Yara Object. 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-2019-5020/ (Markdown: https://insights.sbomify.com/CVE-2019-5020/index.md)","id":"CVE-2019-5020","markdown":"https://insights.sbomify.com/CVE-2019-5020/index.md","name":"CVE-2019-5020","record":{"aliases":["DEBIAN-CVE-2019-5020","GHSA-6r2m-f9j9-h374"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Yara malware analysis library","requires_auth":"none","summary":"An attacker can cause a denial of service in Yara by providing a specially crafted binary file that triggers an assertion failure during object lookup.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"talos","cpe":[{"product":"yara","vendor":"virustotal"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-754","name":"Improper Check for Unusual or Exceptional Conditions"},{"id":"CWE-617","name":"Reachable Assertion"}],"description":"An exploitable denial of service vulnerability exists in the object lookup functionality of Yara 3.8.1.
