Summary

MariaDB server from 10.6.1 before 10.6.28, 10.11.1 before 10.11.19, 11.4.1 before 11.4.13, 11.8.1 before 11.8.9, 12.3.1 before 12.3.3 and 13.0.1 before 13.0.2 is affected. The mysql_json plugin assumes imported MySQL tables hold valid binary JSON, so invalid data causes out-of-bounds reads (CWE-125). An attacker with no privileges who can get a user to import a specially prepared table can cause information disclosure or a server crash.

Description from the CNA

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 mysql_json plugin assumed that imported MySQL tables contained valid MySQL binary JSON data. A specially prepared MySQL table containing invalid JSON data could cause out-of-bounds reads, information disclosure, or a server crash. 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.
