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-2020-13791 in the wild and no public exploit code.\n\nAffected product: Qemu Qemu. 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-2020-13791/ (Markdown: https://insights.sbomify.com/CVE-2020-13791/index.md)","id":"CVE-2020-13791","markdown":"https://insights.sbomify.com/CVE-2020-13791/index.md","name":"CVE-2020-13791","record":{"aliases":["DEBIAN-CVE-2020-13791","GHSA-9j9x-v7hw-3v8f","UBUNTU-CVE-2020-13791"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"QEMU virtualization","requires_auth":"low_privilege","summary":"Guest OS users can trigger out-of-bounds access in QEMU's PCI configuration space, potentially leading to code execution or denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"qemu","vendor":"qemu"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"hw/pci/pci.c in QEMU 4.2.0 allows guest OS users to trigger an out-of-bounds access by providing an address near the end of the PCI configuration space.","ecosystems":[],"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":"Memory corruption in n/a","id":"CVE-2020-13791","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"qemu:qemu","products":["qemu:qemu"],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":4,"next":{"headline":"Path traversal in n/a","id":"CVE-2020-13792"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2020-13790"},"products":["n/a"],"published":"2020-06-04","related":[{"cvss_score":10,"headline":"Null dereference in n/a","id":"CVE-2022-36648","kev_date_added":null,"published":"2023-08-22"},{"cvss_score":10,"headline":"Race condition in n/a","id":"CVE-2015-8556","kev_date_added":null,"published":"2017-03-24"},{"cvss_score":9.9,"headline":"Use after free in n/a","id":"CVE-2009-3616","kev_date_added":null,"published":"2009-10-23"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2019-12928","kev_date_added":null,"published":"2019-06-24"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2019-12929","kev_date_added":null,"published":"2019-06-24"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2018-20815","kev_date_added":null,"published":"2019-05-31"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-8380","kev_date_added":null,"published":"2017-08-28"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Guest OS users can trigger out-of-bounds access in QEMU's PCI configuration space, potentially leading to code execution or denial of service.","url":"https://insights.sbomify.com/CVE-2020-13791/"}
