As I can see it, possible reason is that glite-VOBOX is build with 
"Requires: lcg-infosites = 2.6.2-1" in it's spec file. In that case, 
Maria needs newer or recompiled version of glite-VOBOX that will either 
have "Requires: lcg-infosites >= 2.6.2-1" or "Requires: lcg-infosites = 
Solution for now would be "yum update -x lcg-infosites" do prevent 
lcg-infosites from updating with the rest of the packages.
