MariaDB CONNECT Storage Engine Use-After-Free 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 validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the service account. Was ZDI-CAN-16207.
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
