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-2026-24028 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-2026-24028/ (Markdown: https://insights.sbomify.com/CVE-2026-24028/index.md)","id":"CVE-2026-24028","markdown":"https://insights.sbomify.com/CVE-2026-24028/index.md","name":"CVE-2026-24028","record":{"aliases":["DEBIAN-CVE-2026-24028","GHSA-q26r-j393-x8vq","UBUNTU-CVE-2026-24028"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"DNS load balancer","requires_auth":"none","summary":"Attackers can cause crashes or leak memory by sending crafted DNS packets to PowerDNS DNSdist when custom Lua code parses them.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"OX","cpe":[{"product":"dnsdist","vendor":"powerdns"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-126","name":"Buffer Over-read"}],"description":"An attacker might be able to trigger an out-of-bounds read by sending a crafted DNS response packet, when custom Lua code uses newDNSPacketOverlay to parse DNS packets.
