An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-27455 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mariadb (Bitnami): affected from 10.4.0; fixed in 10.4.25, 10.5.16, 10.6.8, 10.7.4\n- mariadb-min (Bitnami): affected from 10.4.0; fixed in 10.4.25, 10.5.16, 10.6.8, 10.7.4\n- mysql-client (Bitnami): affected from 10.4.0; fixed in 10.4.25, 10.5.16, 10.6.8, 10.7.4\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-2022-27455/ (Markdown: https://insights.sbomify.com/CVE-2022-27455/index.md)","id":"CVE-2022-27455","markdown":"https://insights.sbomify.com/CVE-2022-27455/index.md","name":"CVE-2022-27455","record":{"aliases":["ALPINE-CVE-2022-27455","BIT-mariadb-2022-27455","BIT-mariadb-min-2022-27455","BIT-mysql-client-2022-27455","DEBIAN-CVE-2022-27455","GHSA-5265-h4f9-w9cf","UBUNTU-CVE-2022-27455"],"analysis":{"component_type":"database","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"MariaDB Server","requires_auth":"none","summary":"A use-after-free vulnerability in MariaDB Server allows attackers to potentially execute arbitrary code or cause a denial of service.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mariadb","vendor":"mariadb"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"MariaDB Server v10.6.3 and below was discovered to contain an use-after-free in the component my_wildcmp_8bit_impl at /strings/ctype-simple.c.","ecosystems":["Bitnami"],"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":"Use after free in n/a","id":"CVE-2022-27455","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"mariadb:mariadb","products":["mariadb:mariadb"],"type":"use_after_free","year":"2022"},"n_packages":3,"n_references":2,"next":{"headline":"Use after free in n/a","id":"CVE-2022-27456"},"packages":[{"ecosystem":"Bitnami","fixed":["10.4.25","10.5.16","10.6.8","10.7.4"],"introduced":["10.4.0","10.5.0","10.6.0","10.7.0"],"last_affected":[],"package":"mariadb","purl":"pkg:bitnami/mariadb","source":"BIT-mariadb-2022-27455"},{"ecosystem":"Bitnami","fixed":["10.4.25","10.5.16","10.6.8","10.7.4"],"introduced":["10.4.0","10.5.0","10.6.0","10.7.0"],"last_affected":[],"package":"mariadb-min","purl":"pkg:bitnami/mariadb-min","source":"BIT-mariadb-min-2022-27455"},{"ecosystem":"Bitnami","fixed":["10.4.25","10.5.16","10.6.8","10.7.4"],"introduced":["10.4.0","10.5.0","10.6.0","10.7.0"],"last_affected":[],"package":"mysql-client","purl":"pkg:bitnami/mysql-client","source":"BIT-mysql-client-2022-27455"}],"prev":{"headline":"Null dereference in n/a","id":"CVE-2022-27452"},"products":["n/a"],"published":"2022-04-14","related":[{"cvss_score":10,"headline":"MariaDB server has unsafe parameter handling in `wsrep_notify_cmd`","id":"CVE-2026-49261","kev_date_added":null,"published":"2026-06-11"},{"cvss_score":9.9,"headline":"MariaDB: Out-of-bound buffer write on in `ST_AsText` of nested GeometryCollections","id":"CVE-2026-85746","kev_date_added":null,"published":"2026-10-16"},{"cvss_score":9.9,"headline":"MariaDB: Use-after-free with a large number of SYS_REFCURSOR's","id":"CVE-2026-85748","kev_date_added":null,"published":"2026-10-16"},{"cvss_score":9.9,"headline":"MariaDB: Numerous issues caused by historical #mysql50# tablename encoding bypass.","id":"CVE-2026-92262","kev_date_added":null,"published":"2026-10-16"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2023-26785","kev_date_added":null,"published":"2024-10-17"},{"cvss_score":8.8,"headline":"MariaDB: GRANT PROXY with empty password incorrectly checks grantor's privileges","id":"CVE-2026-97380","kev_date_added":null,"published":"2026-10-16"},{"cvss_score":8.6,"headline":"Heap-based Buffer Overflow in MariaDB","id":"CVE-2026-32710","kev_date_added":null,"published":"2026-03-20"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"2024-08-03","vendors":["n/a"]},"summary":"A use-after-free vulnerability in MariaDB Server allows attackers to potentially execute arbitrary code or cause a denial of service.","url":"https://insights.sbomify.com/CVE-2022-27455/"}
