An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2017-14493 exists.\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-2017-14493/ (Markdown: https://insights.sbomify.com/CVE-2017-14493/index.md)","id":"CVE-2017-14493","markdown":"https://insights.sbomify.com/CVE-2017-14493/index.md","name":"CVE-2017-14493","record":{"aliases":["ALPINE-CVE-2017-14493","CLEANSTART-2026-CB16973","DEBIAN-CVE-2017-14493","GHSA-7mpq-366q-m6vq","UBUNTU-CVE-2017-14493"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"DNS and DHCP server","requires_auth":"none","summary":"Remote attackers can execute arbitrary code or cause a crash in dnsmasq via a crafted DHCPv6 request due to a stack-based buffer overflow.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"leap","vendor":"opensuse"},{"product":"enterprise_linux_desktop","vendor":"redhat"},{"product":"enterprise_linux_server","vendor":"redhat"},{"product":"enterprise_linux_workstation","vendor":"redhat"},{"product":"dnsmasq","vendor":"thekelleys"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Stack-based buffer overflow in dnsmasq before 2.78 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted DHCPv6 request.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2017-10-02","github_poc":1,"max_poc_stars":5,"metasploit":0,"nuclei":0,"refs":[{"date":"2018-12-04T08:15:53Z","kind":"github_poc","ref":"https://github.com/pupiles/bof-dnsmasq-cve-2017-14493","stars":5,"title":"dnsmasq rop exploit with NX bypass"},{"date":"2017-10-02","kind":"exploitdb","ref":"42943","stars":null,"title":"Dnsmasq \u003c 2.78 - Stack Overflow"}],"tier":"weaponised"},"has_fix":true,"headline":"Memory corruption in n/a","id":"CVE-2017-14493","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"canonical:ubuntu_linux","products":["canonical:ubuntu_linux","debian:debian_linux","opensuse:leap","redhat:enterprise_linux_desktop","redhat:enterprise_linux_server","redhat:enterprise_linux_workstation"],"type":"memory_corruption","year":"2017"},"n_packages":0,"n_references":20,"next":{"headline":"Information disclosure in n/a","id":"CVE-2017-14494"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2017-14492"},"products":["n/a"],"published":"2017-10-02","related":[{"cvss_score":9.8,"headline":"SaltStack Salt Authentication Bypass","id":"CVE-2020-11651","kev_date_added":"2021-11-03","published":"2020-04-30"},{"cvss_score":9.8,"headline":"OpenSMTPD Remote Code Execution","id":"CVE-2020-7247","kev_date_added":"2022-03-25","published":"2020-01-29"},{"cvss_score":9.8,"headline":"Exim Out-of-bounds Write","id":"CVE-2019-16928","kev_date_added":"2022-03-03","published":"2019-09-27"},{"cvss_score":9.8,"headline":"Exim Buffer Overflow","id":"CVE-2018-6789","kev_date_added":"2021-11-03","published":"2018-02-08"},{"cvss_score":9.8,"headline":"Oracle Java SE and Java SE Embedded Remote Code Execution","id":"CVE-2015-2590","kev_date_added":"2022-03-03","published":"2015-07-16"},{"cvss_score":9.8,"headline":"Oracle JRE Remote Code Execution","id":"CVE-2013-0422","kev_date_added":"2022-05-25","published":"2013-01-10"},{"cvss_score":9.8,"headline":"Oracle Java SE Runtime Environment (JRE) Arbitrary Code Execution","id":"CVE-2011-3544","kev_date_added":"2022-03-03","published":"2011-10-19"}],"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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code or cause a crash in dnsmasq via a crafted DHCPv6 request due to a stack-based buffer overflow.","url":"https://insights.sbomify.com/CVE-2017-14493/"}
