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-2025-30194 in the wild and no public exploit code.\n\nAffected product: PowerDNS DNSdist. 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-2025-30194/ (Markdown: https://insights.sbomify.com/CVE-2025-30194/index.md)","id":"CVE-2025-30194","markdown":"https://insights.sbomify.com/CVE-2025-30194/index.md","name":"CVE-2025-30194","record":{"aliases":["DEBIAN-CVE-2025-30194","GHSA-487w-xx5j-gqwc","openSUSE-SU-2025:15157-1"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"DNS load balancer","requires_auth":"none","summary":"An attacker can cause a denial of service in DNSdist by triggering a double-free crash via a crafted DoH exchange when using the nghttp2 provider.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"OX","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"When DNSdist is configured to provide DoH via the nghttp2 provider, an attacker can cause a denial of service by crafting a DoH exchange that triggers an illegal memory access (double-free) and crash of DNSdist, causing a denial of service.\n\nThe remedy is: upgrade to the patched 1.9.9 version.\n\nA workaround is to temporarily switch to the h2o provider until DNSdist has been upgraded to a fixed version.\n\nWe would like to thank Charles Howes for bringing this issue to our attention.","ecosystems":["openSUSE:Tumbleweed"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Denial of service via crafted DoH exchange","id":"CVE-2025-30194","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2025"},"n_packages":1,"n_references":1,"next":{"headline":"A crafted zone can lead to an illegal memory access in the PowerDNS Recursor","id":"CVE-2025-30195"},"packages":[{"ecosystem":"openSUSE:Tumbleweed","fixed":["1.9.10-2.1"],"introduced":["0"],"last_affected":[],"package":"dnsdist","purl":"pkg:rpm/opensuse/dnsdist\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2025:15157-1"}],"prev":{"headline":"Denial of service via crafted TCP exchange","id":"CVE-2025-30193"},"products":["DNSdist"],"published":"2025-04-29","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-06-20","vendors":["PowerDNS"]},"summary":"An attacker can cause a denial of service in DNSdist by triggering a double-free crash via a crafted DoH exchange when using the nghttp2 provider.","url":"https://insights.sbomify.com/CVE-2025-30194/"}
