Please stop distributing node.js v0.10 - and move to latest io.js or at least node 0.12.6 to make latest security patches available.

I upgraded succesfully our Kibana 4.1.1 installation to io 2.3.3 on Linux 64 by following steps:

npm n -g 
n io 2.3.3
cd kibana/src
mv node_modules node_modules_old_0_10
npm i 

then change bin/kibana start script

NODE=/usr/local/bin/node
