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-2014-7840 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-2014-7840/ (Markdown: https://insights.sbomify.com/CVE-2014-7840/index.md)","id":"CVE-2014-7840","markdown":"https://insights.sbomify.com/CVE-2014-7840/index.md","name":"CVE-2014-7840","record":{"aliases":["DEBIAN-CVE-2014-7840","GHSA-m2wj-gq82-h93m","UBUNTU-CVE-2014-7840"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"QEMU virtualization","requires_auth":"none","summary":"Remote attackers can execute arbitrary code on QEMU hosts by sending crafted migration data, affecting virtualization infrastructure.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"qemu","vendor":"qemu"},{"product":"enterprise_linux_desktop","vendor":"redhat"},{"product":"enterprise_linux_eus","vendor":"redhat"},{"product":"enterprise_linux_server","vendor":"redhat"},{"product":"enterprise_linux_server_aus","vendor":"redhat"},{"product":"enterprise_linux_workstation","vendor":"redhat"},{"product":"virtualization","vendor":"redhat"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"AV:N/AC:L/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"The host_from_stream_offset function in arch_init.c in QEMU, when loading RAM during migration, allows remote attackers to execute arbitrary code via a crafted (1) offset or (2) length value in savevm data.","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-2014-7840","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"qemu:qemu","products":["qemu:qemu","redhat:enterprise_linux_desktop","redhat:enterprise_linux_eus","redhat:enterprise_linux_server","redhat:enterprise_linux_server_aus","redhat:enterprise_linux_workstation","redhat:virtualization"],"type":"memory_corruption","year":"2014"},"n_packages":0,"n_references":6,"next":{"headline":"Null dereference in n/a","id":"CVE-2014-7841"},"packages":[],"prev":{"headline":"XML External Entity Reference in RESTEasy","id":"CVE-2014-7839"},"products":["n/a"],"published":"2014-12-12","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":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code on QEMU hosts by sending crafted migration data, affecting virtualization infrastructure.","url":"https://insights.sbomify.com/CVE-2014-7840/"}
