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-2020-18897 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-2020-18897/ (Markdown: https://insights.sbomify.com/CVE-2020-18897/index.md)","id":"CVE-2020-18897","markdown":"https://insights.sbomify.com/CVE-2020-18897/index.md","name":"CVE-2020-18897","record":{"aliases":["DEBIAN-CVE-2020-18897","GHSA-8whc-587x-j3fm","UBUNTU-CVE-2020-18897"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Libpff library","requires_auth":"none","summary":"Attackers can execute arbitrary code or cause denial of service via a crafted PFF file due to a use-after-free flaw in the Libpff library.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libpff","vendor":"libpff_project"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"An use-after-free vulnerability in the libpff_item_tree_create_node function of libyal Libpff before 20180623 allows attackers to cause a denial of service (DOS) or execute arbitrary code via a crafted pff file.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Use after free in n/a","id":"CVE-2020-18897","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Denial of service in n/a","id":"CVE-2020-18898"},"packages":[],"prev":{"headline":"Missing authorization in n/a","id":"CVE-2020-18890"},"products":["n/a"],"published":"2021-08-19","related":[{"cvss_score":5.5,"headline":"Denial of service in n/a","id":"CVE-2018-20348","kev_date_added":null,"published":"2018-12-22"},{"cvss_score":5.5,"headline":"Information disclosure in n/a","id":"CVE-2018-11723","kev_date_added":null,"published":"2018-06-19"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can execute arbitrary code or cause denial of service via a crafted PFF file due to a use-after-free flaw in the Libpff library.","url":"https://insights.sbomify.com/CVE-2020-18897/"}
