CVE-2022-24052

MariaDB CONNECT Storage Engine Heap-based Buffer Overflow Privilege
Escalation Vulnerability. This vulnerability allows local attackers to
escalate privileges on affected installations of MariaDB. Authentication is
required to exploit this vulnerability. The specific flaw exists within the
processing of SQL queries. The issue results from the lack of proper
validation of the length of user-supplied data prior to copying it to a
fixed-length heap-based buffer. An attacker can leverage this vulnerability
to escalate privileges and execute arbitrary code in the context of the
service account. Was ZDI-CAN-16190.
