The second one there is CVE-2012-3383. 3.4.1 remained affected; fixed in

We are more specific on our version pages. From

 * Fix unfiltered HTML capabilities in multisite (this is CVE-2012-3383)
 * Fix possible privilege escalation in the Atom Publishing Protocol
 * Allow operations on network plugins only through the network admin

Details for the other two:

for users of an author role or higher. This should be considered low risk,
impact. An additional mitigating factor is that AtomPub is off by default

 * For multisite, plugins that must be activated network-wide could be
activated by a non-network administrator. This is only if they were already
installed by a network administrator, but left inactive. This could also
occur if the network administrator allowed individual site administrators to
manage plugins -- by default, this is not the case, and it is rare. Again,
particularly high risk or impact.
