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-2009-4420 in the wild and no public exploit code.\n\nAffected product: F5 Big-Ip Application Security 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-2009-4420/ (Markdown: https://insights.sbomify.com/CVE-2009-4420/index.md)","id":"CVE-2009-4420","markdown":"https://insights.sbomify.com/CVE-2009-4420/index.md","name":"CVE-2009-4420","record":{"aliases":["GHSA-jggw-46hj-wcq8"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"F5 BIG-IP ASM","requires_auth":"none","summary":"Remote attackers can cause a denial of service in F5 BIG-IP ASM and PSM via a buffer overflow in the bd daemon.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"big-ip_application_security_manager","vendor":"f5"},{"product":"big-ip_protocol_security_manager","vendor":"f5"},{"product":"big-ip_protocol_security_module","vendor":"f5"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:C","version":"2.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Buffer overflow in the bd daemon in F5 Networks BIG-IP Application Security Manager (ASM) 9.4.4 through 9.4.7 and 10.0.0 through 10.0.1, and Protocol Security Manager (PSM) 9.4.5 through 9.4.7 and 10.0.0 through 10.0.1, allows remote attackers to cause a denial of service (crash) via unknown vectors.
