- Details
-
mysqlinstalldb 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 authpamtooldir/authpamtool. NOTE: this does not affect the Oracle MySQL product, which implements mysqlinstall_db differently.
