MariaDB is an enhanced, drop-in replacement for MySQL.
It was discovered that MariaDB did not properly validate the content of a packet received from a server.
A remote attacker could send a specially crafted packet to WSREP service, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.
There is no known workaround at this time.
