Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The MariaDB Connector/J Maven package org.mariadb.jdbc:mariadb-java-client is affected in versions 3.0.0 up to but not including 3.3.7, 3.4.0 up to but not including 3.4.5, and 3.5.0 up to but not including 3.5.11. In XA recovery, the driver trusted length values sent by the database server without validating them, so a malicious or compromised server, or an attacker in a man-in-the-middle position, could crash recovery or cause large memory allocations. Upgrade to version 3.3.7, 3.4.5, 3.5.11 or later.
