Vulnerability Description
MariaDB Connector/J is used to connect applications developed in Java to MariaDB and MySQL databases. From 3.0.0 until 3.3.7, 3.4.5, and 3.5.11, the MariaDbPoolConnection.recover() and MariaDbPoolPinnedConnection.recover() implementations trusted the gtrid_length and bqual_length columns returned by XA RECOVER. The methods allocated and split Xid byte arrays without validating the lengths against Xid.MAXGTRIDSIZE, Xid.MAXBQUALSIZE, or the actual data payload. A malicious or compromised server, or a machine-in-the-middle attacker, could cause large allocations, NegativeArraySizeException, or ArrayIndexOutOfBoundsException during XA recovery. This issue is fixed in versions 3.3.7, 3.4.5, and 3.5.11.
