Описание
One byte out-of-bound buffer write in DOS tables of the CONNECT engine
Impact
Incorrect boundary checked made it possible to write one '\0' byte beyond the end of the stack based buffer at the attacker controlled offset. This was demonstrated to cause a remote code execution in the lab conditions.
Patches
Fixed in 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, 13.0.2.
Workarounds
Make sure you do not have CONNECT engine plugin installed if you don't need it.

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.
