An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2016-2147 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-2016-2147/ (Markdown: https://insights.sbomify.com/CVE-2016-2147/index.md)","id":"CVE-2016-2147","markdown":"https://insights.sbomify.com/CVE-2016-2147/index.md","name":"CVE-2016-2147","record":{"aliases":["ALPINE-CVE-2016-2147","DEBIAN-CVE-2016-2147","GHSA-3wxp-8cgp-vmq4","UBUNTU-CVE-2016-2147"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"BusyBox DHCP client","requires_auth":"none","summary":"Remote attackers can crash the BusyBox DHCP client by sending a malformed domain name, causing a denial of service.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"busybox","vendor":"busybox"},{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"Integer overflow in the DHCP client (udhcpc) in BusyBox before 1.25.0 allows remote attackers to cause a denial of service (crash) via a malformed RFC1035-encoded domain name, which triggers an out-of-bounds heap write.","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":"Integer overflow in n/a","id":"CVE-2016-2147","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"canonical:ubuntu_linux","products":["canonical:ubuntu_linux","debian:debian_linux"],"type":"integer_overflow","year":"2016"},"n_packages":0,"n_references":14,"next":{"headline":"Memory corruption in n/a","id":"CVE-2016-2148"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2016-2146"},"products":["n/a"],"published":"2017-02-09","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Remote attackers can crash the BusyBox DHCP client by sending a malformed domain name, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2016-2147/"}
