Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2013-4154 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-2013-4154/ (Markdown: https://insights.sbomify.com/CVE-2013-4154/index.md)","id":"CVE-2013-4154","markdown":"https://insights.sbomify.com/CVE-2013-4154/index.md","name":"CVE-2013-4154","record":{"aliases":["DEBIAN-CVE-2013-4154","GHSA-99hg-84w9-fwh7"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Virtualization management","requires_auth":"low_privilege","summary":"Remote attackers can crash the libvirt daemon via a NULL pointer dereference when the guest agent is unconfigured, 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":4.3,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[],"description":"The qemuAgentCommand function in libvirt before 1.1.1, when a guest agent is not configured, allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via vectors related to \"agent based cpu (un)plug,\" as demonstrated by the \"virsh vcpucount foobar --guest\" 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-2013-4154","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":5,"next":{"headline":"OpenStack Swift allows authenticated users to cause a denial of service","id":"CVE-2013-4155"},"packages":[],"prev":{"headline":"Use after free in n/a","id":"CVE-2013-4153"},"products":["n/a"],"published":"2013-09-30","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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can crash the libvirt daemon via a NULL pointer dereference when the guest agent is unconfigured, causing denial of service.","url":"https://insights.sbomify.com/CVE-2013-4154/"}
