An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-36222 and fix it if it is affected.\n\nWhat it is: CVE-2021-36222 is a high-severity vulnerability in Debian Debian Linux, published on 22 Jul 2021. 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-2021-36222 in the wild and no public exploit code.\n\nAffected product: Debian Debian Linux. 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-2021-36222/ (Markdown: https://insights.sbomify.com/CVE-2021-36222/index.md)","id":"CVE-2021-36222","markdown":"https://insights.sbomify.com/CVE-2021-36222/index.md","name":"CVE-2021-36222","record":{"aliases":["ALPINE-CVE-2021-36222","AZL-6607","CLEANSTART-2024-BR37030","DEBIAN-CVE-2021-36222","DSA-4944-1","GHSA-7gwg-3h62-pwf5","OESA-2021-1283","SUSE-SU-2021:2800-1","UBUNTU-CVE-2021-36222","openSUSE-SU-2021:1182-1","openSUSE-SU-2021:2800-1"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"MIT Kerberos KDC","requires_auth":"none","summary":"Remote attackers can crash the MIT Kerberos KDC daemon via a NULL pointer dereference in the pre-authentication verification process.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"kerberos_5","vendor":"mit"},{"product":"active_iq_unified_manager","vendor":"netapp"},{"product":"oncommand_insight","vendor":"netapp"},{"product":"oncommand_workflow_automation","vendor":"netapp"},{"product":"snapcenter","vendor":"netapp"},{"product":"mysql_server","vendor":"oracle"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"ec_verify in kdc/kdc_preauth_ec.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.18.4 and 1.19.x before 1.19.2 allows remote attackers to cause a NULL pointer dereference and daemon crash.
