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-2016-7476 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-2016-7476/ (Markdown: https://insights.sbomify.com/CVE-2016-7476/index.md)","id":"CVE-2016-7476","markdown":"https://insights.sbomify.com/CVE-2016-7476/index.md","name":"CVE-2016-7476","record":{"aliases":["GHSA-j6wf-w5r4-84pv"],"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":"Remote attackers can cause a denial of service in F5 BIG-IP devices by sending crafted TCP packets that trigger a memory leak in the Traffic Management Microkernel.","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_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"},{"product":"big-ip_protocol_security_module","vendor":"f5"},{"product":"big-ip_websafe","vendor":"f5"}],"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-20","name":"Improper Input Validation"}],"description":"The Traffic Management Microkernel (TMM) in F5 BIG-IP LTM, AAM, AFM, APM, ASM, GTM, Link Controller, PEM, PSM, and WebSafe 11.6.0 before 11.6.0 HF6, 11.5.0 before 11.5.3 HF2, and 11.3.0 before 11.4.1 HF10 may suffer from a memory leak while handling certain types of TCP traffic.
