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-2018-19967 in the wild and no public exploit code.\n\nAffected product: Debian Debian Linux. 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-2018-19967/ (Markdown: https://insights.sbomify.com/CVE-2018-19967/index.md)","id":"CVE-2018-19967","markdown":"https://insights.sbomify.com/CVE-2018-19967/index.md","name":"CVE-2018-19967","record":{"aliases":["ALPINE-CVE-2018-19967","DEBIAN-CVE-2018-19967","GHSA-qr6c-xrp9-38xv","SUSE-SU-2019:0875-1","UBUNTU-CVE-2018-19967","openSUSE-SU-2019:1199-1"],"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":"Guest OS users can cause a host OS hang on Intel x86 platforms due to improper handling of HLE transactions.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"xen","vendor":"xen"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"An issue was discovered in Xen through 4.11.x on Intel x86 platforms allowing guest OS users to cause a denial of service (host OS hang) because Xen does not work around Intel's mishandling of certain HLE transactions associated with the KACQUIRE instruction prefix.","ecosystems":["SUSE:Linux Enterprise Module for Basesystem 15","SUSE:Linux Enterprise Module for Server Applications 15","openSUSE:Leap 15.0"],"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-2018-19967","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"debian:debian_linux","products":["debian:debian_linux","xen:xen"],"type":"denial_of_service","year":"2018"},"n_packages":3,"n_references":6,"next":{"headline":"phpMyAdmin Local file inclusion through transformation feature","id":"CVE-2018-19968"},"packages":[{"ecosystem":"SUSE:Linux Enterprise Module for Basesystem 15","fixed":["4.10.3_02-3.14.1"],"introduced":["0"],"last_affected":[],"package":"xen","purl":"pkg:rpm/suse/xen\u0026distro=SUSE%20Linux%20Enterprise%20Module%20for%20Basesystem%2015","source":"SUSE-SU-2019:0875-1"},{"ecosystem":"SUSE:Linux Enterprise Module for Server Applications 15","fixed":["4.10.3_02-3.14.1"],"introduced":["0"],"last_affected":[],"package":"xen","purl":"pkg:rpm/suse/xen\u0026distro=SUSE%20Linux%20Enterprise%20Module%20for%20Server%20Applications%2015","source":"SUSE-SU-2019:0875-1"},{"ecosystem":"openSUSE:Leap 15.0","fixed":["4.10.3_02-lp150.2.16.1"],"introduced":["0"],"last_affected":[],"package":"xen","purl":"pkg:rpm/opensuse/xen\u0026distro=openSUSE%20Leap%2015.0","source":"openSUSE-SU-2019:1199-1"}],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2018-19966"},"products":["n/a"],"published":"2018-12-08","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"SUSE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"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":"2024-08-05","vendors":["n/a"]},"summary":"Guest OS users can cause a host OS hang on Intel x86 platforms due to improper handling of HLE transactions.","url":"https://insights.sbomify.com/CVE-2018-19967/"}
