Title
MariaDB: one byte OOB write in DOS tables of the CONNECT engine
Summary
MariaDB server is a community developed fork of MySQL server. From 10.6.1 until 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2, the CONNECT engine's DOS table type used an incorrect boundary check that permitted a one-byte null write beyond a stack buffer at an attacker-controlled offset. An authenticated user able to use the CONNECT engine could cause a crash and potentially remote code execution. This issue is fixed in versions 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2.
