I would be very glad if someone could explain what the 1: before the package name signifies.

1 is the RPM epoch number. It overrides the normal comparison order on version checking. So, if there is some odd reason why you as a packager want to mark a lower version number as an upgrade, you can tag it with an Epoch number.
yum info xorg-x11-xauth
Name : xorg-x11-xauth
Arch : x86_64
Epoch : 1
Version : 1.0.9
Release : 1.el7
Size : 30 k
Repo : base/7/x86_64
Summary : X.Org X11 X authority utilities

Description : xauth is used to edit and display the authorization information
: used in connecting to an X server.
Following the file mode bits is a single character that specifies
whether an alternate access method such as an access control list
applies to the file. When the character following the file mode
bits is a space, there is no alternate access method. When it is
a printing character, then there is such a method.
GNU `ls' uses a `.' character to indicate a file with an SELinux
security context, but no other alternate access method.
A file with any other combination of alternate access methods is
marked with a `+' character.
