It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-14367 and fix it if it is affected.\n\nWhat it is: CVE-2020-14367 is a medium-severity path traversal vulnerability in Canonical Ubuntu Linux, published on 24 Aug 2020. 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-2020-14367 in the wild and no public exploit code.\n\nAffected product: Canonical Ubuntu Linux. 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-2020-14367/ (Markdown: https://insights.sbomify.com/CVE-2020-14367/index.md)","id":"CVE-2020-14367","markdown":"https://insights.sbomify.com/CVE-2020-14367/index.md","name":"CVE-2020-14367","record":{"aliases":["ALPINE-CVE-2020-14367","DEBIAN-CVE-2020-14367","GHSA-73h7-c2xm-9mrv","MGASA-2020-0341","SUSE-SU-2021:4147-1","SUSE-SU-2022:0845-1","SUSE-SU-2022:0845-2","UBUNTU-CVE-2020-14367","USN-4475-1","openSUSE-SU-2022:0845-1","openSUSE-SU-2024:10682-1"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"NTP time synchronization","requires_auth":"high_privilege","summary":"An attacker with privileged access can exploit a symlink vulnerability in chrony's PID file creation to overwrite arbitrary files, causing data loss and denial of service.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"fedora","vendor":"fedoraproject"},{"product":"chrony","vendor":"tuxfamily"}],"cvss":{"score":6,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"A flaw was found in chrony versions before 3.5.1 when creating the PID file under the /var/run/chrony folder.
