This package uses eclasses which were vulnerable to root privilege escalation via "chown", see bug 630822 for details. The eclasses were fixed, however a rev bump is required to ensure that the vulnerability is completely removed.
Fixed through bump to >=dev-db/mariadb-galera-10.0.32. Repository is clean.
GLSA Vote: Yes (will be added to an existing GLSA for the other dev-db/* packages).
All done, repository is clean.
