An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-42382 in the wild and no public exploit code.\n\nAffected product: Fedoraproject Fedora. 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-2021-42382/ (Markdown: https://insights.sbomify.com/CVE-2021-42382/index.md)","id":"CVE-2021-42382","markdown":"https://insights.sbomify.com/CVE-2021-42382/index.md","name":"CVE-2021-42382","record":{"aliases":["ALPINE-CVE-2021-42382","AZL-6349","DEBIAN-CVE-2021-42382","GHSA-xpm2-jxrf-prmx","UBUNTU-CVE-2021-42382"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"BusyBox utility","requires_auth":"high_privilege","summary":"Attackers can cause denial of service or potentially execute code via a crafted awk pattern in BusyBox's awk applet.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"JFROG","cpe":[{"product":"busybox","vendor":"busybox"},{"product":"fedora","vendor":"fedoraproject"}],"cvss":{"score":7.2,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"A use-after-free in Busybox's awk applet leads to denial of service and possibly code execution when processing a crafted awk pattern in the getvar_s function","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 busybox","id":"CVE-2021-42382","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"fedoraproject:fedora","products":["fedoraproject:fedora"],"type":"use_after_free","year":"2021"},"n_packages":0,"n_references":5,"next":{"headline":"Use after free in busybox","id":"CVE-2021-42383"},"packages":[],"prev":{"headline":"Use after free in busybox","id":"CVE-2021-42381"},"products":["busybox"],"published":"2021-11-15","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2022-48174","kev_date_added":null,"published":"2023-08-22"},{"cvss_score":9.8,"headline":"Memory corruption in busybox","id":"CVE-2021-42377","kev_date_added":null,"published":"2021-11-15"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2016-2148","kev_date_added":null,"published":"2017-02-09"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2022-28391","kev_date_added":null,"published":"2022-04-03"},{"cvss_score":8.8,"headline":"Code injection in n/a","id":"CVE-2017-16544","kev_date_added":null,"published":"2017-11-20"},{"cvss_score":8,"headline":"Memory corruption in n/a","id":"CVE-2018-1000517","kev_date_added":null,"published":"2018-06-26"},{"cvss_score":7.8,"headline":"Path traversal in n/a","id":"CVE-2023-39810","kev_date_added":null,"published":"2023-08-28"}],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-11-03","vendors":["busybox"]},"summary":"Attackers can cause denial of service or potentially execute code via a crafted awk pattern in BusyBox's awk applet.","url":"https://insights.sbomify.com/CVE-2021-42382/"}
