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-1999-0918 exists.\n\nAffected product: Microsoft Windows 2000. 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-1999-0918/ (Markdown: https://insights.sbomify.com/CVE-1999-0918/index.md)","id":"CVE-1999-0918","markdown":"https://insights.sbomify.com/CVE-1999-0918/index.md","name":"CVE-1999-0918","record":{"aliases":["GHSA-gfwh-p42r-qh79"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows OS","requires_auth":"none","summary":"Attackers can cause denial of service on Windows systems by sending malformed fragmented IGMP packets.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"windows_2000","vendor":"microsoft"},{"product":"windows_95","vendor":"microsoft"},{"product":"windows_98","vendor":"microsoft"},{"product":"windows_nt","vendor":"microsoft"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:C","version":"2.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Denial of service in various Windows systems via malformed, fragmented IGMP packets.","ecosystems":[],"exploits":{"exploitdb":3,"first_seen":"1999-04-06","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"1999-04-06","kind":"exploitdb","ref":"19415","stars":null,"title":"Microsoft Windows 95/98 / NT Enterprise Server 4.0 SP5 / NT Terminal Server 4.0 SP4 / NT Workstation 4.0 SP5 - Denial of Service (3)"},{"date":"1999-07-03","kind":"exploitdb","ref":"19413","stars":null,"title":"Microsoft Windows 95/98 / NT Enterprise Server 4.0 SP5 / NT Terminal Server 4.0 SP4 / NT Workstation 4.0 SP5 - Denial of Service (1)"},{"date":"1999-07-03","kind":"exploitdb","ref":"19414","stars":null,"title":"Microsoft Windows 95/98 / NT Enterprise Server 4.0 SP5 / NT Terminal Server 4.0 SP4 / NT Workstation 4.0 SP5 - Denial of Service (2)"}],"tier":"weaponised"},"has_fix":null,"headline":"Denial of service in n/a","id":"CVE-1999-0918","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_2000","products":["microsoft:windows_2000","microsoft:windows_98","microsoft:windows_nt"],"type":"denial_of_service","year":"1999"},"n_packages":0,"n_references":3,"next":{"headline":"Denial of service in n/a","id":"CVE-1999-0919"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-1999-0917"},"products":["n/a"],"published":"2000-01-04","related":[{"cvss_score":9.8,"headline":"Microsoft Windows Buffer Overflow","id":"CVE-2008-4250","kev_date_added":"2026-05-20","published":"2008-10-23"},{"cvss_score":7.8,"headline":"Microsoft Windows Kernel Exception Handler","id":"CVE-2010-0232","kev_date_added":"2022-03-03","published":"2010-01-21"},{"cvss_score":7.8,"headline":"Microsoft Windows Improper Input Validation","id":"CVE-2009-1123","kev_date_added":"2022-03-03","published":"2009-06-10"},{"cvss_score":7.8,"headline":"Microsoft Windows Privilege Escalation","id":"CVE-2002-0367","kev_date_added":"2022-03-03","published":"2003-04-02"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2010-0269","kev_date_added":null,"published":"2010-04-14"},{"cvss_score":10,"headline":"Weak cryptography in n/a","id":"CVE-2010-0231","kev_date_added":null,"published":"2010-02-10"},{"cvss_score":10,"headline":"Auth bypass in n/a","id":"CVE-2009-3677","kev_date_added":null,"published":"2009-12-09"}],"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"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-01","vendors":["n/a"]},"summary":"Attackers can cause denial of service on Windows systems by sending malformed fragmented IGMP packets.","url":"https://insights.sbomify.com/CVE-1999-0918/"}
