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-2013-6436 in the wild and no public exploit code.\n\nAffected product: Redhat Libvirt. 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-2013-6436/ (Markdown: https://insights.sbomify.com/CVE-2013-6436/index.md)","id":"CVE-2013-6436","markdown":"https://insights.sbomify.com/CVE-2013-6436/index.md","name":"CVE-2013-6436","record":{"aliases":["DEBIAN-CVE-2013-6436","GHSA-3r95-9fm6-xqcf"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Virtualization management","requires_auth":"low_privilege","summary":"Local users can crash the libvirtd daemon by querying memory parameters of a shutting down LXC guest, causing denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"libvirt","vendor":"redhat"}],"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 lxcDomainGetMemoryParameters method in lxc/lxc_driver.c in libvirt 1.0.5 through 1.2.0 does not properly check the status of LXC guests when reading memory tunables, which allows local users to cause a denial of service (NULL pointer dereference and libvirtd crash) via a guest in the shutdown status, as demonstrated by the \"virsh memtune\" command.","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":"Null dereference in n/a","id":"CVE-2013-6436","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"redhat:libvirt","products":["redhat:libvirt"],"type":"null_dereference","year":"2013"},"n_packages":0,"n_references":8,"next":{"headline":"OpenStack Nova DoS through ephemeral disk backing files","id":"CVE-2013-6437"},"packages":[],"prev":{"headline":"Race condition in n/a","id":"CVE-2013-6435"},"products":["n/a"],"published":"2014-01-07","related":[{"cvss_score":8.5,"headline":"Missing authorization in n/a","id":"CVE-2013-4401","kev_date_added":null,"published":"2013-11-02"},{"cvss_score":7.7,"headline":"Null dereference in libvirt","id":"CVE-2017-2635","kev_date_added":null,"published":"2018-08-22"},{"cvss_score":7.2,"headline":"Privilege escalation in n/a","id":"CVE-2013-4400","kev_date_added":null,"published":"2013-12-09"},{"cvss_score":6.9,"headline":"Privilege escalation in n/a","id":"CVE-2013-4291","kev_date_added":null,"published":"2013-09-30"},{"cvss_score":6.9,"headline":"Missing authorization in n/a","id":"CVE-2011-1146","kev_date_added":null,"published":"2011-03-15"},{"cvss_score":6.8,"headline":"Race condition in n/a","id":"CVE-2013-6458","kev_date_added":null,"published":"2014-01-24"},{"cvss_score":6.5,"headline":"Missing authorization in libvirt","id":"CVE-2020-10701","kev_date_added":null,"published":"2021-05-27"}],"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 users can crash the libvirtd daemon by querying memory parameters of a shutting down LXC guest, causing denial of service.","url":"https://insights.sbomify.com/CVE-2013-6436/"}
