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-2019-11555 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-2019-11555/ (Markdown: https://insights.sbomify.com/CVE-2019-11555/index.md)","id":"CVE-2019-11555","markdown":"https://insights.sbomify.com/CVE-2019-11555/index.md","name":"CVE-2019-11555","record":{"aliases":["ALPINE-CVE-2019-11555","DEBIAN-CVE-2019-11555","DSA-4450-1","GHSA-3r3j-9m7c-h35g","UBUNTU-CVE-2019-11555","USN-3969-1","USN-3969-2"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Wi-Fi authentication software","requires_auth":"none","summary":"An attacker can cause a denial of service in hostapd or wpa_supplicant by sending unexpected EAP-pwd fragments, triggering a NULL pointer dereference.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"hostapd","vendor":"w1.fi"},{"product":"wpa_supplicant","vendor":"w1.fi"}],"cvss":{"score":5.9,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"The EAP-pwd implementation in hostapd (EAP server) before 2.8 and wpa_supplicant (EAP peer) before 2.8 does not validate fragmentation reassembly state properly for a case where an unexpected fragment could be received.
