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-2017-12134 in the wild and no public exploit code.\n\nAffected product: Citrix Xenserver. 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-2017-12134/ (Markdown: https://insights.sbomify.com/CVE-2017-12134/index.md)","id":"CVE-2017-12134","markdown":"https://insights.sbomify.com/CVE-2017-12134/index.md","name":"CVE-2017-12134","record":{"aliases":["DEBIAN-CVE-2017-12134","GHSA-c46p-g2h9-xcvx","UBUNTU-CVE-2017-12134"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation","data_read","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Xen hypervisor","requires_auth":"low_privilege","summary":"Local guest users can corrupt block device data to leak memory, cause DoS, or escalate privileges to the host OS via incorrect IO merge calculations.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"xenserver","vendor":"citrix"},{"product":"xen","vendor":"xen"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-682","name":"Incorrect Calculation"}],"description":"The xen_biovec_phys_mergeable function in drivers/xen/biomerge.c in Xen might allow local OS guest users to corrupt block device data streams and consequently obtain sensitive memory information, cause a denial of service, or gain host OS privileges by leveraging incorrect block IO merge-ability calculation.","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-2017-12134","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"citrix:xenserver","products":["citrix:xenserver","xen:xen"],"type":"memory_corruption","year":"2017"},"n_packages":0,"n_references":10,"next":{"headline":"Privilege escalation in n/a","id":"CVE-2017-12135"},"packages":[],"prev":{"headline":"Use after free in n/a","id":"CVE-2017-12133"},"products":["n/a"],"published":"2017-08-24","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2014-4947","kev_date_added":null,"published":"2014-07-22"},{"cvss_score":9.8,"headline":"Path traversal in n/a","id":"CVE-2018-14007","kev_date_added":null,"published":"2018-08-15"},{"cvss_score":9.8,"headline":"Denial of service in n/a","id":"CVE-2015-7705","kev_date_added":null,"published":"2017-08-07"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2016-5302","kev_date_added":null,"published":"2016-06-13"},{"cvss_score":8.8,"headline":"Privilege escalation in n/a","id":"CVE-2017-12135","kev_date_added":null,"published":"2017-08-24"},{"cvss_score":8.8,"headline":"Privilege escalation in n/a","id":"CVE-2017-12137","kev_date_added":null,"published":"2017-08-24"}],"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":"Local guest users can corrupt block device data to leak memory, cause DoS, or escalate privileges to the host OS via incorrect IO merge calculations.","url":"https://insights.sbomify.com/CVE-2017-12134/"}
