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-1999-0016/ (Markdown: https://insights.sbomify.com/CVE-1999-0016/index.md)","id":"CVE-1999-0016","markdown":"https://insights.sbomify.com/CVE-1999-0016/index.md","name":"CVE-1999-0016","record":{"aliases":["GHSA-5mw4-cxpf-cxvj"],"analysis":null,"analysis_generated_by":null,"assigner":"mitre","cpe":[{"product":"ios","vendor":"cisco"},{"product":"inet","vendor":"gnu"},{"product":"hp-ux","vendor":"hp"},{"product":"windows_95","vendor":"microsoft"},{"product":"windows_nt","vendor":"microsoft"},{"product":"winsock","vendor":"microsoft"},{"product":"netbsd","vendor":"netbsd"},{"product":"sunos","vendor":"sun"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[],"description":"Land IP denial of service.","ecosystems":[],"exploits":{"exploitdb":5,"first_seen":"1997-11-20","github_poc":2,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"1997-11-20","kind":"exploitdb","ref":"20810","stars":null,"title":"FreeBSD 2.x / HP-UX 9/10/11 / Kernel 2.0.3 / Windows NT 4.0/Server 2003 / NetBSD 1 - 'land.c' loopback Denial of Service (1)"},{"date":"1997-11-20","kind":"exploitdb","ref":"20811","stars":null,"title":"FreeBSD 2.x / HP-UX 9/10/11 / Kernel 2.0.3 / Windows NT 4.0/Server 2003 / NetBSD 1 - 'land.c' loopback Denial of Service (2)"},{"date":"1997-11-20","kind":"exploitdb","ref":"20812","stars":null,"title":"FreeBSD 2.x / HP-UX 9/10/11 / Kernel 2.0.3 / Windows NT 4.0/Server 2003 / NetBSD 1 - 'land.c' loopback Denial of Service (3)"},{"date":"1997-11-20","kind":"exploitdb","ref":"20813","stars":null,"title":"FreeBSD 2.x / HP-UX 9/10/11 / Kernel 2.0.3 / Windows NT 4.0/Server 2003 / NetBSD 1 - 'land.c' loopback Denial of Service (4)"},{"date":"1997-11-20","kind":"exploitdb","ref":"20814","stars":null,"title":"FreeBSD 2.x / HP-UX 9/10/11 / Kernel 2.0.3 / Windows NT 4.0/Server 2003 / NetBSD 1 - 'land.c' loopback Denial of Service (5)"},{"date":"2020-04-01T15:47:31Z","kind":"github_poc","ref":"https://github.com/pexmee/CVE-1999-0016-Land-DOS-tool","stars":0,"title":"A simple dos-tool "},{"date":"2021-04-01T21:00:13Z","kind":"github_poc","ref":"https://github.com/Pommaq/CVE-1999-0016-POC","stars":0,"title":null}],"tier":"weaponised"},"has_fix":null,"headline":"Land IP denial of service.","id":"CVE-1999-0016","indexable":false,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:ios","products":["cisco:ios","hp:hp-ux","microsoft:windows_nt","netbsd:netbsd","sun:sunos"],"type":null,"year":"1999"},"n_packages":0,"n_references":1,"next":{"headline":"Server-side request forgery in n/a","id":"CVE-1999-0017"},"packages":[],"prev":{"headline":"Teardrop IP denial of service.","id":"CVE-1999-0015"},"products":["n/a"],"published":"1999-09-29","related":[{"cvss_score":9.8,"headline":"Cisco IOS and IOS XE Software DHCP Remote Code Execution","id":"CVE-2017-12240","kev_date_added":"2022-03-03","published":"2017-09-28"},{"cvss_score":9.8,"headline":"Cisco IOS and IOS XE Remote Code Execution","id":"CVE-2017-3881","kev_date_added":"2022-03-25","published":"2017-03-17"},{"cvss_score":8.8,"headline":"Cisco IOS, XR, and XE Software Buffer Overflow","id":"CVE-2018-0167","kev_date_added":"2022-03-03","published":"2018-03-28"},{"cvss_score":8.8,"headline":"Cisco IOS and IOS XE Software SNMP Remote Code Execution","id":"CVE-2017-6736","kev_date_added":"2022-03-03","published":"2017-07-17"},{"cvss_score":8.8,"headline":"Cisco IOS and IOS XE Software SNMP Remote Code Execution","id":"CVE-2017-6737","kev_date_added":"2022-03-03","published":"2017-07-17"},{"cvss_score":8.8,"headline":"Cisco IOS and IOS XE Software SNMP Remote Code Execution","id":"CVE-2017-6738","kev_date_added":"2022-03-03","published":"2017-07-17"},{"cvss_score":8.8,"headline":"Cisco IOS and IOS XE Software SNMP Remote Code Execution","id":"CVE-2017-6739","kev_date_added":"2022-03-03","published":"2017-07-17"}],"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":"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":"2025-03-17","vendors":["n/a"]},"summary":null,"url":"https://insights.sbomify.com/CVE-1999-0016/"}
