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-2018-7184 in the wild and no public exploit code.\n\nAffected product: Canonical Ubuntu Linux. 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-2018-7184/ (Markdown: https://insights.sbomify.com/CVE-2018-7184/index.md)","id":"CVE-2018-7184","markdown":"https://insights.sbomify.com/CVE-2018-7184/index.md","name":"CVE-2018-7184","record":{"aliases":["DEBIAN-CVE-2018-7184","GHSA-rf4v-73h8-p6f7","UBUNTU-CVE-2018-7184"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"NTP daemon","requires_auth":"none","summary":"Remote attackers can cause a denial of service in the NTP daemon by sending packets with zero-origin timestamps, disrupting time synchronization.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"cloud_backup","vendor":"netapp"},{"product":"steelstore_cloud_integrated_storage","vendor":"netapp"},{"product":"ntp","vendor":"ntp"},{"product":"slackware_linux","vendor":"slackware"},{"product":"diskstation_manager","vendor":"synology"},{"product":"router_manager","vendor":"synology"},{"product":"skynas","vendor":"synology"},{"product":"virtual_diskstation_manager","vendor":"synology"},{"product":"vs960hd_firmware","vendor":"synology"}],"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":[],"description":"ntpd in ntp 4.2.8p4 before 4.2.8p11 drops bad packets before updating the \"received\" timestamp, which allows remote attackers to cause a denial of service (disruption) by sending a packet with a zero-origin timestamp causing the association to reset and setting the contents of the packet as the most recent timestamp.
