Remediation section below for
Debian:10 relevant versions.
A flaw was found in the mysql-wsrep component of mariadb. Lack of input sanitization in
wsrep_sst_method allows for command injection that can be exploited by a remote attacker to execute arbitrary commands on galera cluster nodes. 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.
mariadb-10.3 to version 1:10.3.25-0+deb10u1 or higher.
