RCE in Galeracluster Galera Cluster For MySQL
CVE-2020-15180
A flaw was found in the mysql-wsrep component of mariadb.

This threatens the system's confidentiality, integrity, and availability. This flaw affects mariadb versions before 10.1.47, before 10.2.34, before 10.3.25, before 10.4.15 and before 10.5.6.
