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-2012-3494 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-2012-3494/ (Markdown: https://insights.sbomify.com/CVE-2012-3494/index.md)","id":"CVE-2012-3494","markdown":"https://insights.sbomify.com/CVE-2012-3494/index.md","name":"CVE-2012-3494","record":{"aliases":["DEBIAN-CVE-2012-3494","GHSA-6p48-jg39-2mq7"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["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 crash the host system by writing to reserved bits in the debug control register on x86-64 Xen hypervisors.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"xenserver","vendor":"citrix"},{"product":"xen","vendor":"xen"}],"cvss":{"score":2.1,"severity":"low","source":"nvd","vector":"AV:L/AC:L/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-264","name":null}],"description":"The set_debugreg hypercall in include/asm-x86/debugreg.h in Xen 4.0, 4.1, and 4.2, and Citrix XenServer 6.0.2 and earlier, when running on x86-64 systems, allows local OS guest users to cause a denial of service (host crash) by writing to the reserved bits of the DR7 debug control register.","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":"Denial of service in n/a","id":"CVE-2012-3494","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"citrix:xenserver","products":["citrix:xenserver","xen:xen"],"type":"denial_of_service","year":"2012"},"n_packages":0,"n_references":25,"next":{"headline":"Denial of service in n/a","id":"CVE-2012-3495"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2012-3493"},"products":["n/a"],"published":"2012-11-23","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 crash the host system by writing to reserved bits in the debug control register on x86-64 Xen hypervisors.","url":"https://insights.sbomify.com/CVE-2012-3494/"}
