Red Hat Security Advisory: mariadb-galera security update
Severity
Important
Notes
Topic: An update for mariadb-galera is now available for Red Hat OpenStack
Platform 10 (Newton).
Red Hat Product Security has rated this update as having a security impact
of High. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.
Details: MariaDB is a multi-user, multi-threaded SQL database server that is binary
compatible with MySQL. Galera is a synchronous multi-master cluster for
MariaDB.
Security Fix(es):
* mariadb-galera: mariadb: Insufficient SST method name check leading to code injection in mysql-wsrep (CVE-2020-15180)
For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page listed in the References section.

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.
