It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-14364 and fix it if it is affected.\n\nWhat it is: CVE-2020-14364 is a medium-severity memory corruption vulnerability in Canonical Ubuntu Linux, published on 31 Aug 2020. It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-14364 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-2020-14364/ (Markdown: https://insights.sbomify.com/CVE-2020-14364/index.md)","id":"CVE-2020-14364","markdown":"https://insights.sbomify.com/CVE-2020-14364/index.md","name":"CVE-2020-14364","record":{"aliases":["ALPINE-CVE-2020-14364","DEBIAN-CVE-2020-14364","GHSA-fq9g-vccc-q7c7","RHSA-2020:4047","RHSA-2020:4048","RHSA-2020:4049","RHSA-2020:4050","RHSA-2020:4051","RHSA-2020:4052","RHSA-2020:4053","RHSA-2020:4054","RHSA-2020:4055","RHSA-2020:4056","RHSA-2020:4058","RHSA-2020:4078","RHSA-2020:4111","RHSA-2020:4162","RHSA-2020:4176","RHSA-2020:4291","UBUNTU-CVE-2020-14364","USN-4511-1"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"QEMU USB emulator","requires_auth":"high_privilege","summary":"A guest user can trigger out-of-bounds access in QEMU's USB emulator to crash the host or execute arbitrary code with host privileges.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"leap","vendor":"opensuse"},{"product":"qemu","vendor":"qemu"},{"product":"enterprise_linux","vendor":"redhat"},{"product":"openstack","vendor":"redhat"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"An out-of-bounds read/write access flaw was found in the USB emulator of the QEMU in versions before 5.2.0.
