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-2011-4151 in the wild and no public exploit code.\n\nAffected product: Mit Kerberos 5. 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-2011-4151/ (Markdown: https://insights.sbomify.com/CVE-2011-4151/index.md)","id":"CVE-2011-4151","markdown":"https://insights.sbomify.com/CVE-2011-4151/index.md","name":"CVE-2011-4151","record":{"aliases":["DEBIAN-CVE-2011-4151","GHSA-3wcv-7r47-m45v"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Kerberos KDC","requires_auth":"none","summary":"Remote attackers can cause a denial of service in MIT Kerberos KDC when using the Berkeley DB backend, requiring an upgrade to mitigate.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"kerberos_5","vendor":"mit"}],"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":"The krb5_db2_lockout_audit function in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.8 through 1.8.4, when the db2 (aka Berkeley DB) back end is used, allows remote attackers to cause a denial of service (assertion failure and daemon exit) via unspecified vectors, a different vulnerability than CVE-2011-1528.","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":"Denial of service in n/a","id":"CVE-2011-4151","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"mit:kerberos_5","products":["mit:kerberos_5"],"type":"denial_of_service","year":"2011"},"n_packages":0,"n_references":3,"next":{"headline":"Null dereference in n/a","id":"CVE-2011-4153"},"packages":[],"prev":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2011-4150"},"products":["n/a"],"published":"2011-10-20","related":[{"cvss_score":10,"headline":"Use after free in n/a","id":"CVE-2011-0285","kev_date_added":null,"published":"2011-04-15"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2008-0947","kev_date_added":null,"published":"2008-03-19"},{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2007-5902","kev_date_added":null,"published":"2007-12-06"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2007-4743","kev_date_added":null,"published":"2007-09-06"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2007-3999","kev_date_added":null,"published":"2007-09-05"},{"cvss_score":10,"headline":"Missing authorization in n/a","id":"CVE-2000-0514","kev_date_added":null,"published":"2000-10-13"},{"cvss_score":9.8,"headline":"Memory corruption in krb5 1.5","id":"CVE-2017-15088","kev_date_added":null,"published":"2017-11-23"}],"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 cause a denial of service in MIT Kerberos KDC when using the Berkeley DB backend, requiring an upgrade to mitigate.","url":"https://insights.sbomify.com/CVE-2011-4151/"}
