According to madison unless you are using old-stable (wheezy) you should have the 4.3 version. You may also enable wheezy-backports repositories.

This may seem like a dumb question, but is it safe to remove 4.2 and then install 4.3? I mean, I have quite few virtual machines each with different config and It would be a pain to recreate that manually :) – SiliconMind – 2013-12-13T20:52:02.500
@SiliconMind Depends what VB has done between 4.2 and 4.3, but there should be no problem. – Braiam – 2013-12-13T21:28:52.410
Damn! After upgrade to 4.3 the bridged network stopped working :( – SiliconMind – 2014-01-08T09:45:06.380
This is weird
ifconfig eth1 down
and thenifconfig eth1 up
in one of the guest systems solved the issue... for all other guests! – SiliconMind – 2014-01-08T11:20:05.500
