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-2009-0847 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-2009-0847/ (Markdown: https://insights.sbomify.com/CVE-2009-0847/index.md)","id":"CVE-2009-0847","markdown":"https://insights.sbomify.com/CVE-2009-0847/index.md","name":"CVE-2009-0847","record":{"aliases":["DEBIAN-CVE-2009-0847","GHSA-ph4p-rhxr-85rq"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Kerberos authentication server","requires_auth":"none","summary":"Remote attackers can crash the Kerberos server via crafted ASN.1 data when PK-INIT is enabled, causing denial of service.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"kerberos","vendor":"mit"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-189","name":null}],"description":"The asn1buf_imbed function in the ASN.1 decoder in MIT Kerberos 5 (aka krb5) 1.6.3, when PK-INIT is used, allows remote attackers to cause a denial of service (application crash) via a crafted length value that triggers an erroneous malloc call, related to incorrect calculations with pointer arithmetic.","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":"Integer overflow in n/a","id":"CVE-2009-0847","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2009"},"n_packages":0,"n_references":39,"next":{"headline":"Path traversal in n/a","id":"CVE-2009-0848"},"packages":[],"prev":{"headline":"Use after free in n/a","id":"CVE-2009-0846"},"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 server via crafted ASN.1 data when PK-INIT is enabled, causing denial of service.","url":"https://insights.sbomify.com/CVE-2009-0847/"}
