======================================

When I check the 4340558 page, there is a difference in the
descriptions (i.e. when it should be installed).

As can be seen above, it says it is to be installed for 4.7.2. I have
4.7.2 installed and running fine. So, it needs to be intalled.

When one checks the 4340558 page, there is no 4.7.2 in the description
field (i.e. it is NOT for 4.7.2). The initial update did NOT have this
update checked when the system checked for updates.

But when it the description showed it was for 4.7.2 (and other
vulnerabilities), I checked it to install it. Then the failures began.
