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-2018-11237 in the wild and no public exploit code.\n\nAffected product: Canonical Ubuntu 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-2018-11237/ (Markdown: https://insights.sbomify.com/CVE-2018-11237/index.md)","id":"CVE-2018-11237","markdown":"https://insights.sbomify.com/CVE-2018-11237/index.md","name":"CVE-2018-11237","record":{"aliases":["DEBIAN-CVE-2018-11237","GHSA-fh43-5v3x-c3vr","UBUNTU-CVE-2018-11237"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GNU C Library","requires_auth":"low_privilege","summary":"A buffer overflow in glibc's mempcpy function allows attackers to execute arbitrary code or cause denial of service via crafted inputs.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"glibc","vendor":"gnu"},{"product":"data_ontap_edge","vendor":"netapp"},{"product":"element_software_management","vendor":"netapp"},{"product":"communications_session_border_controller","vendor":"oracle"},{"product":"enterprise_communications_broker","vendor":"oracle"},{"product":"enterprise_linux_desktop","vendor":"redhat"},{"product":"enterprise_linux_server","vendor":"redhat"},{"product":"enterprise_linux_workstation","vendor":"redhat"},{"product":"virtualization_host","vendor":"redhat"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"An AVX-512-optimized implementation of the mempcpy function in the GNU C Library (aka glibc or libc6) 2.27 and earlier may write data beyond the target buffer, leading to a buffer overflow in __mempcpy_avx512_no_vzeroupper.","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":"Memory corruption in n/a","id":"CVE-2018-11237","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"canonical:ubuntu_linux","products":["canonical:ubuntu_linux","gnu:glibc","redhat:enterprise_linux_desktop","redhat:enterprise_linux_server","redhat:enterprise_linux_workstation","redhat:virtualization_host"],"type":"memory_corruption","year":"2018"},"n_packages":0,"n_references":9,"next":{"headline":"Integer overflow in n/a","id":"CVE-2018-11239"},"packages":[],"prev":{"headline":"Integer overflow in n/a","id":"CVE-2018-11236"},"products":["n/a"],"published":"2018-05-18","related":[{"cvss_score":9.8,"headline":"SaltStack Salt Authentication Bypass","id":"CVE-2020-11651","kev_date_added":"2021-11-03","published":"2020-04-30"},{"cvss_score":9.8,"headline":"OpenSMTPD Remote Code Execution","id":"CVE-2020-7247","kev_date_added":"2022-03-25","published":"2020-01-29"},{"cvss_score":9.8,"headline":"Exim Out-of-bounds Write","id":"CVE-2019-16928","kev_date_added":"2022-03-03","published":"2019-09-27"},{"cvss_score":9.8,"headline":"Exim Buffer Overflow","id":"CVE-2018-6789","kev_date_added":"2021-11-03","published":"2018-02-08"},{"cvss_score":9.8,"headline":"Oracle Java SE and Java SE Embedded Remote Code Execution","id":"CVE-2015-2590","kev_date_added":"2022-03-03","published":"2015-07-16"},{"cvss_score":9.8,"headline":"Oracle JRE Remote Code Execution","id":"CVE-2013-0422","kev_date_added":"2022-05-25","published":"2013-01-10"},{"cvss_score":9.8,"headline":"Oracle Java SE Runtime Environment (JRE) Arbitrary Code Execution","id":"CVE-2011-3544","kev_date_added":"2022-03-03","published":"2011-10-19"}],"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":"2024-08-05","vendors":["n/a"]},"summary":"A buffer overflow in glibc's mempcpy function allows attackers to execute arbitrary code or cause denial of service via crafted inputs.","url":"https://insights.sbomify.com/CVE-2018-11237/"}
