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-2004-0257 in the wild and no public exploit code.\n\nAffected product: Netbsd Netbsd. 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-2004-0257/ (Markdown: https://insights.sbomify.com/CVE-2004-0257/index.md)","id":"CVE-2004-0257","markdown":"https://insights.sbomify.com/CVE-2004-0257/index.md","name":"CVE-2004-0257","record":{"aliases":["GHSA-vqm2-c8wp-mmg7"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenBSD NetBSD OS","requires_auth":"none","summary":"Remote attackers can crash OpenBSD and NetBSD systems by sending specific IPv6 packets to listening ports, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"netbsd","vendor":"netbsd"},{"product":"openbsd","vendor":"openbsd"}],"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":"OpenBSD 3.4 and NetBSD 1.6 and 1.6.1 allow remote attackers to cause a denial of service (crash) by sending an IPv6 packet with a small MTU to a listening port and then issuing a TCP connect to that port.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Denial of service in n/a","id":"CVE-2004-0257","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"netbsd:netbsd","products":["netbsd:netbsd","openbsd:openbsd"],"type":"denial_of_service","year":"2004"},"n_packages":0,"n_references":8,"next":{"headline":"Memory corruption in n/a","id":"CVE-2004-0258"},"packages":[],"prev":{"headline":"GNU libtool before 1.5.2, during compile time, allows local users to overwrite arbitrary files via a symlink attack on libtool directories in /tmp.","id":"CVE-2004-0256"},"products":["n/a"],"published":"2004-09-01","related":[{"cvss_score":9.8,"headline":"Security feature bypass in n/a","id":"CVE-2017-1000374","kev_date_added":null,"published":"2017-06-19"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-1000375","kev_date_added":null,"published":"2017-06-19"},{"cvss_score":9.8,"headline":"Denial of service in n/a","id":"CVE-2017-1000378","kev_date_added":null,"published":"2017-06-19"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2015-8212","kev_date_added":null,"published":"2017-01-19"},{"cvss_score":9.3,"headline":"Denial of service in n/a","id":"CVE-2008-3584","kev_date_added":null,"published":"2008-09-11"},{"cvss_score":9.3,"headline":"Security feature bypass in n/a","id":"CVE-2008-1335","kev_date_added":null,"published":"2008-03-13"},{"cvss_score":7.8,"headline":"Path traversal in n/a","id":"CVE-2016-6253","kev_date_added":null,"published":"2017-01-20"}],"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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-08","vendors":["n/a"]},"summary":"Remote attackers can crash OpenBSD and NetBSD systems by sending specific IPv6 packets to listening ports, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2004-0257/"}
