Summary

MariaDB Connector/J, the Java JDBC driver used to connect applications to MariaDB and MySQL databases, is affected. A malicious or compromised database server, or an attacker intercepting the connection, could send crafted packets that cause the driver to read beyond packet boundaries, leading to crashes that terminate connection handling.

Summarized by anthropic/claude-haiku-5.5. Verify details against the original sources.

Read the original 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, decoders for OK packet session-state blocks, column definition packets, text row data, or binary row data used server-declared lengths without confirming that the requested bytes remained in the receive buffer. The decoders could position reads, create sub-buffers, or decode strings beyond the packet boundary. A malicious or compromised server, or a machine-in-the-middle attacker, could trigger unchecked ArrayIndexOutOfBoundsException or IllegalArgumentException failures inside JDBC calls and terminate connection handling. This issue is fixed in versions 3.3.7, 3.4.5, and 3.5.11.
