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-2018-1000168 in the wild and no public exploit code.\n\nAffected product: Debian Debian 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-2018-1000168/ (Markdown: https://insights.sbomify.com/CVE-2018-1000168/index.md)","id":"CVE-2018-1000168","markdown":"https://insights.sbomify.com/CVE-2018-1000168/index.md","name":"CVE-2018-1000168","record":{"aliases":["ALPINE-CVE-2018-1000168","CLEANSTART-2026-PZ96090","CLEANSTART-2026-QW15283","DEBIAN-CVE-2018-1000168","GHSA-q6fc-wp2r-hvq3","UBUNTU-CVE-2018-1000168"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"HTTP/2 library","requires_auth":"none","summary":"A remote attacker can cause a segmentation fault and denial of service in nghttp2 by sending a malformed ALTSVC frame.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"nghttp2","vendor":"nghttp2"},{"product":"node.js","vendor":"nodejs"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","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-20","name":"Improper Input Validation"},{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"nghttp2 version \u003e= 1.10.0 and nghttp2 \u003c= v1.31.0 contains an Improper Input Validation CWE-20 vulnerability in ALTSVC frame handling that can result in segmentation fault leading to denial of service.
