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-2009-0844 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-2009-0844/ (Markdown: https://insights.sbomify.com/CVE-2009-0844/index.md)","id":"CVE-2009-0844","markdown":"https://insights.sbomify.com/CVE-2009-0844/index.md","name":"CVE-2009-0844","record":{"aliases":["DEBIAN-CVE-2009-0844","GHSA-4h8p-gqwx-mmw3"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Kerberos authentication","requires_auth":"none","summary":"Remote attackers can crash the Kerberos daemon or read sensitive memory via a crafted length value in SPNEGO implementation.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"kerberos","vendor":"mit"},{"product":"kerberos_5","vendor":"mit"}],"cvss":{"score":5.8,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:P/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"The get_input_token function in the SPNEGO implementation in MIT Kerberos 5 (aka krb5) 1.5 through 1.6.3 allows remote attackers to cause a denial of service (daemon crash) and possibly obtain sensitive information via a crafted length value that triggers a buffer over-read.","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":"Memory corruption in n/a","id":"CVE-2009-0844","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"mit:kerberos_5","products":["mit:kerberos_5"],"type":"memory_corruption","year":"2009"},"n_packages":0,"n_references":39,"next":{"headline":"Null dereference in n/a","id":"CVE-2009-0845"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2009-0843"},"products":["n/a"],"published":"2009-04-09","related":[{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2009-4212","kev_date_added":null,"published":"2010-01-13"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2004-0523","kev_date_added":null,"published":"2004-06-03"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2010-0283","kev_date_added":null,"published":"2010-02-21"},{"cvss_score":7.5,"headline":"Integer overflow in n/a","id":"CVE-2018-5709","kev_date_added":null,"published":"2018-01-16"},{"cvss_score":7.5,"headline":"Auth bypass in n/a","id":"CVE-2003-0138","kev_date_added":null,"published":"2003-03-21"},{"cvss_score":7.5,"headline":"Auth bypass in n/a","id":"CVE-2003-0139","kev_date_added":null,"published":"2003-03-21"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-1999-1321","kev_date_added":null,"published":"2002-03-09"}],"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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-07","vendors":["n/a"]},"summary":"Remote attackers can crash the Kerberos daemon or read sensitive memory via a crafted length value in SPNEGO implementation.","url":"https://insights.sbomify.com/CVE-2009-0844/"}
