Are you sure this is the default behaviour of a Red Hat installation? Your
advisory does not indicate any specific version(s) of Red Hat Linux. Is
this supposed to apply to RHL 7.2? 7.3? 8.0? 9.0? Fedora 1? In my previous
experience with the 'mysql-server' package on any Red Hat the root user is
granted full access without a password, but that is limited only to
connections from the localhost. I've verified that the most up-to-date
'mysql-server' package for Red Hat Enterprise Linux 3 still falls in the 3.x
version, not 4.x. The package name is mysql-server-3.23.58-1. Additionally
with this package from Red Hat the root user without a password is limited
to the localhost only.
Perhaps you could provide some more specific details such as the version of
Red Hat Linux you used, the package you used to install MySQL (as well as
its source), or the third-party installation you used (perhaps a tar ball
from the MySQL project?). I don't think Red Hat will take your advisory
seriously unless you can point out the particulars of this vulnerability.
