Advisory is missing issues fixed since 52.1-8+deb8u4:

  * Backport upstream security fix for CVE-2017-14952: double free in
    createMetazoneMappings() (closes: #878840).

  * Backport upstream security fix for CVE-2017-7867 and CVE-2017-7868,
    heap-buffer-overflow in utf8TextAccess.



Otherwise verified:
* Upstream binary imported into errata4.2-3
* No additional UCS patches in 4.2

deb8u6 was already imported and released for errata4.2-3:
 <https://forge.univention.org/bugzilla/show_bug.cgi?id=44415>
 <http://errata.software-univention.de/ucs/4.2/247.html>
 <http://xen1.knut.univention.de:8000/packages/source/icu/?since=4.2&before=4.3>

So this is only the one mentioned CVE.
Nothing more to do from my side.
