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-2019-6612 in the wild and no public exploit code.\n\nAffected product: F5 Big-Ip Access Policy Manager. 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-2019-6612/ (Markdown: https://insights.sbomify.com/CVE-2019-6612/index.md)","id":"CVE-2019-6612","markdown":"https://insights.sbomify.com/CVE-2019-6612/index.md","name":"CVE-2019-6612","record":{"aliases":["GHSA-mch4-462r-25hp"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"F5 BIG-IP","requires_auth":"none","summary":"Aborted DNS TCP connections can cause the Traffic Management Microkernel to restart, leading to a denial of service on F5 BIG-IP devices.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"f5","cpe":[{"product":"big-ip_access_policy_manager","vendor":"f5"},{"product":"big-ip_advanced_firewall_manager","vendor":"f5"},{"product":"big-ip_application_acceleration_manager","vendor":"f5"},{"product":"big-ip_application_security_manager","vendor":"f5"},{"product":"big-ip_domain_name_system","vendor":"f5"},{"product":"big-ip_global_traffic_manager","vendor":"f5"},{"product":"big-ip_link_controller","vendor":"f5"},{"product":"big-ip_local_traffic_manager","vendor":"f5"},{"product":"big-ip_policy_enforcement_manager","vendor":"f5"}],"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":[],"description":"On BIG-IP 14.0.0-14.1.0.1, 13.0.0-13.1.1.4, 12.1.0-12.1.4, 11.6.1-11.6.3.4, and 11.5.2-11.5.8, DNS query TCP connections that are aborted before receiving a response from a DNS cache may cause TMM to restart.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Denial of service in BIG-IP (LTM, AAM, AFM, APM, ASM, DNS, GTM, Link Controller, PEM)","id":"CVE-2019-6612","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"f5:big-ip_access_policy_manager","products":["f5:big-ip_access_policy_manager","f5:big-ip_advanced_firewall_manager","f5:big-ip_application_acceleration_manager","f5:big-ip_application_security_manager","f5:big-ip_domain_name_system","f5:big-ip_global_traffic_manager","f5:big-ip_link_controller","f5:big-ip_local_traffic_manager","f5:big-ip_policy_enforcement_manager"],"type":"denial_of_service","year":"2019"},"n_packages":0,"n_references":2,"next":{"headline":"Information disclosure in BIG-IP (LTM, AAM, AFM, Analytics, APM, ASM, DNS, Edge Gateway, FPS, GTM, Link Controller, PEM, WebAccelerator)","id":"CVE-2019-6613"},"packages":[],"prev":{"headline":"Denial of service in BIG-IP (LTM, AAM, AFM, Analytics, APM, ASM, DNS, Edge Gateway, FPS, GTM, Link Controller, PEM, WebAccelerator)","id":"CVE-2019-6611"},"products":["BIG-IP (LTM, AAM, AFM, APM, ASM, DNS, GTM, Link Controller, PEM)"],"published":"2019-05-03","related":[{"cvss_score":9.8,"headline":"F5 BIG-IP Configuration Utility Authentication Bypass","id":"CVE-2023-46747","kev_date_added":"2023-10-31","published":"2023-10-26"},{"cvss_score":9.8,"headline":"F5 BIG-IP Missing Authentication","id":"CVE-2022-1388","kev_date_added":"2022-05-10","published":"2022-05-05"},{"cvss_score":9.8,"headline":"F5 BIG-IP and BIG-IQ Centralized Management iControl REST Remote Code Execution","id":"CVE-2021-22986","kev_date_added":"2021-11-03","published":"2021-03-31"},{"cvss_score":9.8,"headline":"F5 BIG-IP Traffic Management Microkernel Buffer Overflow","id":"CVE-2021-22991","kev_date_added":"2022-01-18","published":"2021-03-31"},{"cvss_score":9.8,"headline":"F5 BIG-IP Traffic Management User Interface (TMUI) Remote Code Execution","id":"CVE-2020-5902","kev_date_added":"2021-11-03","published":"2020-07-01"},{"cvss_score":9.3,"headline":"F5 BIG-IP APM Heap-based Buffer Overflow","id":"CVE-2026-94127","kev_date_added":"2026-09-22","published":"2026-09-22"},{"cvss_score":9.3,"headline":"F5 BIG-IP Stack-Based Buffer Overflow","id":"CVE-2025-53521","kev_date_added":"2026-03-27","published":"2025-10-15"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["F5"]},"summary":"Aborted DNS TCP connections can cause the Traffic Management Microkernel to restart, leading to a denial of service on F5 BIG-IP devices.","url":"https://insights.sbomify.com/CVE-2019-6612/"}
