From 10.6.1 until 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2, the CONNECT engine's DOS table type used an incorrect boundary check that permitted a one-byte null write beyond a stack buffer at an attacker-controlled offset. An authenticated user able to use the CONNECT engine could cause a crash and potentially remote code execution. This issue is fixed in versions 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2.","cvssScore":8.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H","cwes":["CWE-787"],"vendors":["mariadb"],"products":["mariadb"],"references":[{"url":"https://github.com/MariaDB/server/commit/b369925f6855d3e1f0ebcf453492724b99fda6f8","tags":["Patch"]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-10.11.19","tags":["Release Notes"]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-10.6.28","tags":["Release Notes"]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-11.4.13","tags":["Release Notes"]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-11.8.9","tags":["Release Notes"]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-12.3.3","tags":["Release Notes"]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-13.0.2","tags":["Release Notes"]},{"url":"https://github.com/MariaDB/server/security/advisories/GHSA-4wgx-ffg9-jrwq","tags":["Vendor Advisory"]},{"url":"https://jira.mariadb.org/browse/MDEV-40637","tags":["Issue Tracking"]}],"exploitRefs":[{"url":"https://github.com/MariaDB/server/commit/b369925f6855d3e1f0ebcf453492724b99fda6f8","tags":["Patch"]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-10.11.19","tags":["Release Notes"]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-10.6.28","tags":["Release Notes"]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-11.4.13","tags":["Release Notes"]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-11.8.9","tags":["Release Notes"]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-12.3.3","tags":["Release Notes"]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-13.0.2","tags":["Release Notes"]},{"url":"https://github.com/MariaDB/server/security/advisories/GHSA-4wgx-ffg9-jrwq","tags":["Vendor Advisory"]}],"hasPoc":true,"ai":{"summary":"A buffer overflow in MariaDB's CONNECT engine allows authenticated users to write one byte past a stack buffer boundary, potentially leading to denial of service or remote code execution.
