An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2018-14645 and fix it if it is affected.\n\nWhat it is: CVE-2018-14645 is a high-severity denial of service vulnerability in Canonical Ubuntu Linux, published on 21 Sep 2018. 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-2018-14645 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-2018-14645/ (Markdown: https://insights.sbomify.com/CVE-2018-14645/index.md)","id":"CVE-2018-14645","markdown":"https://insights.sbomify.com/CVE-2018-14645/index.md","name":"CVE-2018-14645","record":{"aliases":["DEBIAN-CVE-2018-14645","GHSA-gr9c-vx25-2fh5","RHBA-2019:0028","RHSA-2018:2882","UBUNTU-CVE-2018-14645","USN-3780-1"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"HAProxy load balancer","requires_auth":"none","summary":"A remote attacker can cause a denial of service in HAProxy via an out-of-bounds read in the HTTP/2 HPACK decoder.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"haproxy","vendor":"haproxy"},{"product":"enterprise_linux","vendor":"redhat"},{"product":"openshift","vendor":"redhat"},{"product":"openshift_container_platform","vendor":"redhat"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"A flaw was discovered in the HPACK decoder of HAProxy, before 1.8.14, that is used for HTTP/2.
