Comment 1 Andrej Nemec 2016-12-21 09:35:32 EST 
Created cxf tracking bugs for this issue:

Affects: fedora-all [bug 1406813]
Comment 5 Jason Shepherd 2016-12-22 00:25:40 EST 
JBoss EAP 6 and 7 implement JAX-RS using Resteasy, not CXF. Therefore the vulnerable AbstractAtomProvider class is not part of either distribution. Setting EAP 6 and 7 layered productgs as not affected.
