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-2017-15107 in the wild and no public exploit code.\n\nAffected product: Simon Kelley dnsmasq. 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-2017-15107/ (Markdown: https://insights.sbomify.com/CVE-2017-15107/index.md)","id":"CVE-2017-15107","markdown":"https://insights.sbomify.com/CVE-2017-15107/index.md","name":"CVE-2017-15107","record":{"aliases":["ALPINE-CVE-2017-15107","CLEANSTART-2026-ND09534","DEBIAN-CVE-2017-15107","GHSA-f999-2m22-345j","SUSE-SU-2019:14190-1","SUSE-SU-2019:1721-1","UBUNTU-CVE-2017-15107"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"DNS server software","requires_auth":"none","summary":"Attackers can bypass DNSSEC validation to spoof hostnames, affecting Dnsmasq users relying on secure DNS resolution.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"dnsmasq","vendor":"thekelleys"}],"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:H/A:N","version":"3.0"},"cwes":[{"id":"CWE-358","name":"Improperly Implemented Security Check for Standard"}],"description":"A vulnerability was found in the implementation of DNSSEC in Dnsmasq up to and including 2.78.
