Описание
MariaDB server is a community developed fork of MySQL server. An authenticated user can crash MariaDB versions 11.4 before 11.4.10 and 11.8 before 11.8.6 via a bug in JSON_SCHEMA_VALID() function. Under certain conditions it might be possible to turn the crash into a remote code execution. These conditions require tight control over memory layout which is generally only attainable in a lab environment. This issue is fixed in MariaDB 11.4.10, MariaDB 11.8.6, and MariaDB 12.2.2.
A flaw was found in MariaDB. An authenticated user can exploit a vulnerability in the JSON_SCHEMA_VALID() function, which may lead to a server crash, resulting in a denial of service. Under specific and controlled conditions, this flaw could potentially be leveraged to achieve remote code execution, allowing an attacker to run arbitrary commands on the affected system.
