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-2011-1529 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-2011-1529/ (Markdown: https://insights.sbomify.com/CVE-2011-1529/index.md)","id":"CVE-2011-1529","markdown":"https://insights.sbomify.com/CVE-2011-1529/index.md","name":"CVE-2011-1529","record":{"aliases":["DEBIAN-CVE-2011-1529","GHSA-54mf-f57f-83fj"],"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 crash the Kerberos KDC daemon via a null pointer dereference when using specific database backends.","user_interaction":"not_required","vuln_class":"null_dereference"},"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 lookup_lockout_policy function in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.8 through 1.8.4 and 1.9 through 1.9.1, when the db2 (aka Berkeley DB) or LDAP back end is used, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via vectors that trigger certain process_as_req errors.","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-2011-1529","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"mit:kerberos_5","products":["mit:kerberos_5"],"type":"null_dereference","year":"2011"},"n_packages":0,"n_references":6,"next":{"headline":"Null dereference in n/a","id":"CVE-2011-1530"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2011-1528"},"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":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can crash the Kerberos KDC daemon via a null pointer dereference when using specific database backends.","url":"https://insights.sbomify.com/CVE-2011-1529/"}
