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-2016-9383 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-2016-9383/ (Markdown: https://insights.sbomify.com/CVE-2016-9383/index.md)","id":"CVE-2016-9383","markdown":"https://insights.sbomify.com/CVE-2016-9383/index.md","name":"CVE-2016-9383","record":{"aliases":["ALPINE-CVE-2016-9383","DEBIAN-CVE-2016-9383","GHSA-qw22-r72h-rf56","UBUNTU-CVE-2016-9383"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","privilege_escalation","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 execute arbitrary code on the host or cause crashes due to broken bit test instruction emulation in Xen.","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-20","name":"Improper Input Validation"}],"description":"Xen, when running on a 64-bit hypervisor, allows local x86 guest OS users to modify arbitrary memory and consequently obtain sensitive information, cause a denial of service (host crash), or execute arbitrary code on the host by leveraging broken emulation of bit test instructions.","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-2016-9383","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"citrix:xenserver","products":["citrix:xenserver","xen:xen"],"type":"memory_corruption","year":"2016"},"n_packages":0,"n_references":5,"next":{"headline":"Xen 4.7 allows local guest OS users to obtain sensitive host information by loading a 32-bit ELF symbol table.","id":"CVE-2016-9384"},"packages":[],"prev":{"headline":"Privilege escalation in n/a","id":"CVE-2016-9382"},"products":["n/a"],"published":"2017-01-23","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":"Memory corruption in n/a","id":"CVE-2017-12134","kev_date_added":null,"published":"2017-08-24"},{"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":"2024-08-06","vendors":["n/a"]},"summary":"Local guest users can execute arbitrary code on the host or cause crashes due to broken bit test instruction emulation in Xen.","url":"https://insights.sbomify.com/CVE-2016-9383/"}
