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-2017-17563 in the wild and no public exploit code.\n\nAffected product: Xen Xen. 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-2017-17563/ (Markdown: https://insights.sbomify.com/CVE-2017-17563/index.md)","id":"CVE-2017-17563","markdown":"https://insights.sbomify.com/CVE-2017-17563/index.md","name":"CVE-2017-17563","record":{"aliases":["ALPINE-CVE-2017-17563","DEBIAN-CVE-2017-17563","GHSA-6mhv-9623-3chf","UBUNTU-CVE-2017-17563"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Xen hypervisor","requires_auth":"low_privilege","summary":"Guest OS users can crash the host or gain privileges via an integer overflow in Xen's shadow mode reference counting.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"xen","vendor":"xen"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"An issue was discovered in Xen through 4.9.x allowing guest OS users to cause a denial of service (host OS crash) or gain host OS privileges by leveraging an incorrect mask for reference-count overflow checking in shadow mode.","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":"Integer overflow in n/a","id":"CVE-2017-17563","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"xen:xen","products":["xen:xen"],"type":"integer_overflow","year":"2017"},"n_packages":0,"n_references":9,"next":{"headline":"Privilege escalation in n/a","id":"CVE-2017-17564"},"packages":[],"prev":{"headline":"Embedthis GoAhead Remote Code Execution","id":"CVE-2017-17562"},"products":["n/a"],"published":"2017-12-12","related":[{"cvss_score":10,"headline":"Privilege escalation in n/a","id":"CVE-2017-10912","kev_date_added":null,"published":"2017-07-05"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2017-10918","kev_date_added":null,"published":"2017-07-05"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2017-10920","kev_date_added":null,"published":"2017-07-05"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2017-10921","kev_date_added":null,"published":"2017-07-05"},{"cvss_score":9.8,"headline":"Mutiple vulnerabilities in the Viridian interface","id":"CVE-2025-27466","kev_date_added":null,"published":"2025-09-11"},{"cvss_score":9.8,"headline":"Mutiple vulnerabilities in the Viridian interface","id":"CVE-2025-58142","kev_date_added":null,"published":"2025-09-11"},{"cvss_score":9.8,"headline":"Mutiple vulnerabilities in the Viridian interface","id":"CVE-2025-58143","kev_date_added":null,"published":"2025-09-11"}],"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":"2024-08-05","vendors":["n/a"]},"summary":"Guest OS users can crash the host or gain privileges via an integer overflow in Xen's shadow mode reference counting.","url":"https://insights.sbomify.com/CVE-2017-17563/"}
