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-2019-12175 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-2019-12175/ (Markdown: https://insights.sbomify.com/CVE-2019-12175/index.md)","id":"CVE-2019-12175","markdown":"https://insights.sbomify.com/CVE-2019-12175/index.md","name":"CVE-2019-12175","record":{"aliases":["GHSA-m47c-xm2p-2v99","UBUNTU-CVE-2019-12175"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Network Security Monitor","requires_auth":"none","summary":"A NULL pointer dereference in the Kerberos parser allows attackers to cause a denial of service in Zeek Network Security Monitor.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"zeek","vendor":"zeek"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"In Zeek Network Security Monitor (formerly known as Bro) before 2.6.2, a NULL pointer dereference in the Kerberos (aka KRB) protocol parser leads to DoS because a case-type index is mishandled.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Null dereference in n/a","id":"CVE-2019-12175","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2019"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege escalation in n/a","id":"CVE-2019-12176"},"packages":[],"prev":{"headline":"Privilege escalation in n/a","id":"CVE-2019-12174"},"products":["n/a"],"published":"2019-07-17","related":[{"cvss_score":8.7,"headline":"Zeek \u003c 8.0.9 Uncontrolled Memory Consumption DoS via FTP Analyzer","id":"CVE-2026-60108","kev_date_added":null,"published":"2026-07-09"},{"cvss_score":8.7,"headline":"Zeek \u003c 8.0.9 Null Pointer Dereference DoS via Kerberos KRB_ERROR Parsing","id":"CVE-2026-60109","kev_date_added":null,"published":"2026-07-09"},{"cvss_score":8.2,"headline":"Other in n/a","id":"CVE-2021-41732","kev_date_added":null,"published":"2021-09-29"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"A NULL pointer dereference in the Kerberos parser allows attackers to cause a denial of service in Zeek Network Security Monitor.","url":"https://insights.sbomify.com/CVE-2019-12175/"}
