mysql_install_db in MariaDB 10.4.7 through 10.4.11 allows privilege
escalation from the mysql user account to root because chown and chmod are
performed unsafely, as demonstrated by a symlink attack on a chmod 04755 of
auth_pam_tool_dir/auth_pam_tool. NOTE: this does not affect the Oracle
MySQL product, which implements mysql_install_db differently.
