You can continue to receive updates for packages that are shared
between Xubuntu and Ubuntu.  Ubuntu 12.04 has support on the
desktop and server until May 26, 2017. The Xubuntu specific packages
will however no longer receive security updates.

you can always choose to run a version of *buntu that no longer
receives support. The question is your risk tolerance. Xubuntu
12.04 is no longer supported, and as such parts of the system
are no longer getting security updates. This just means that
over time as security issues are discovered they won't get fixed
in Xubuntu 12.04

correct this is standard for all Ubuntu derivatives, if their
support window is different than Ubuntu. In this particular case
Xubuntu had a 3 year LTS, while Ubuntu a 5 year lts. So the
packages that are shared with Ubuntu will continue to receive
updates from Ubuntu for 2 more years.

we certainly don't recommend running a system that isn't supported
any more. It is up to you to determine when doing an upgrade is
best for your situation.
