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-2011-4868 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2011-4868/ (Markdown: https://insights.sbomify.com/CVE-2011-4868/index.md)","id":"CVE-2011-4868","markdown":"https://insights.sbomify.com/CVE-2011-4868/index.md","name":"CVE-2011-4868","record":{"aliases":["DEBIAN-CVE-2011-4868","GHSA-q3c7-f665-h5rw"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"ISC DHCP server","requires_auth":"none","summary":"Remote attackers can crash the ISC DHCP server via crafted packets when DDNS and IPv6 are enabled, causing denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"dhcp","vendor":"isc"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"AV:A/AC:L/Au:N/C:N/I:N/A:C","version":"2.0"},"cwes":[{"id":"CWE-399","name":null}],"description":"The logging functionality in dhcpd in ISC DHCP before 4.2.3-P2, when using Dynamic DNS (DDNS) and issuing IPv6 addresses, does not properly handle the DHCPv6 lease structure, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via crafted packets related to a lease-status update.","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":"Null dereference in n/a","id":"CVE-2011-4868","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2011"},"n_packages":0,"n_references":4,"next":{"headline":"Denial of service in n/a","id":"CVE-2011-4869"},"packages":[],"prev":{"headline":"Missing authorization in n/a","id":"CVE-2011-4867"},"products":["n/a"],"published":"2012-01-15","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2009-0692","kev_date_added":null,"published":"2009-07-14"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2011-0413","kev_date_added":null,"published":"2011-01-31"},{"cvss_score":7.5,"headline":"A specially constructed response from a malicious server can cause a buffer overflow in dhclient","id":"CVE-2018-5732","kev_date_added":null,"published":"2019-10-09"},{"cvss_score":6.9,"headline":"Path traversal in n/a","id":"CVE-2009-1893","kev_date_added":null,"published":"2009-07-17"},{"cvss_score":5.7,"headline":"Memory corruption in n/a","id":"CVE-2012-3570","kev_date_added":null,"published":"2012-07-25"},{"cvss_score":5,"headline":"Denial of service in n/a","id":"CVE-2010-3616","kev_date_added":null,"published":"2010-12-17"}],"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":"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":"2024-08-07","vendors":["n/a"]},"summary":"Remote attackers can crash the ISC DHCP server via crafted packets when DDNS and IPv6 are enabled, causing denial of service.","url":"https://insights.sbomify.com/CVE-2011-4868/"}
