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-2012-3496 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-2012-3496/ (Markdown: https://insights.sbomify.com/CVE-2012-3496/index.md)","id":"CVE-2012-3496","markdown":"https://insights.sbomify.com/CVE-2012-3496/index.md","name":"CVE-2012-3496","record":{"aliases":["DEBIAN-CVE-2012-3496","GHSA-gw25-hcr4-7p5h"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Xen hypervisor","requires_auth":"low_privilege","summary":"A local guest kernel can crash the Xen host by triggering a BUG via invalid flags when translating paging mode is disabled.","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":4.7,"severity":"medium","source":"nvd","vector":"AV:L/AC:M/Au:N/C:N/I:N/A:C","version":"2.0"},"cwes":[{"id":"CWE-16","name":null}],"description":"XENMEM_populate_physmap in Xen 4.0, 4.1, and 4.2, and Citrix XenServer 6.0.2 and earlier, when translating paging mode is not used, allows local PV OS guest kernels to cause a denial of service (BUG triggered and host crash) via invalid flags such as MEMF_populate_on_demand.","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-2012-3496","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":23,"next":{"headline":"Null dereference in n/a","id":"CVE-2012-3497"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2012-3495"},"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":"A local guest kernel can crash the Xen host by triggering a BUG via invalid flags when translating paging mode is disabled.","url":"https://insights.sbomify.com/CVE-2012-3496/"}
