It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-3236 exists.\n\nAffected product: Vim Vim. 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-2021-3236/ (Markdown: https://insights.sbomify.com/CVE-2021-3236/index.md)","id":"CVE-2021-3236","markdown":"https://insights.sbomify.com/CVE-2021-3236/index.md","name":"CVE-2021-3236","record":{"aliases":["DEBIAN-CVE-2021-3236","GHSA-v2qw-7m3m-r9qx"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Vim text editor","requires_auth":"none","summary":"Local attackers can cause a denial of service in Vim via a null pointer dereference in the ex_buffer_all method.","user_interaction":"required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"vim","vendor":"vim"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"vim 8.2.2348 is affected by null pointer dereference, allows local attackers to cause a denial of service (DoS) via the ex_buffer_all method.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Null dereference in n/a","id":"CVE-2021-3236","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"vim:vim","products":["vim:vim"],"type":"null_dereference","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"SQL injection in n/a","id":"CVE-2021-3239"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2021-3229"},"products":["n/a"],"published":"2023-08-11","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-20703","kev_date_added":null,"published":"2023-06-20"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2017-6349","kev_date_added":null,"published":"2017-02-27"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2017-6350","kev_date_added":null,"published":"2017-02-27"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2017-5953","kev_date_added":null,"published":"2017-02-10"},{"cvss_score":9.3,"headline":"Command injection in n/a","id":"CVE-2008-3075","kev_date_added":null,"published":"2009-02-21"},{"cvss_score":9.3,"headline":"Command injection in n/a","id":"CVE-2008-3076","kev_date_added":null,"published":"2009-02-21"},{"cvss_score":9.3,"headline":"Command injection in n/a","id":"CVE-2008-6235","kev_date_added":null,"published":"2009-02-21"}],"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":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-10-10","vendors":["n/a"]},"summary":"Local attackers can cause a denial of service in Vim via a null pointer dereference in the ex_buffer_all method.","url":"https://insights.sbomify.com/CVE-2021-3236/"}
