[vlc] unsafe option "sout" has been ignored for security reasons

[Richard Musil]

I am having some issues on latest 0.9 version (built on gentoo with ~x86).
I have been using vlc on my router (running gentoo) to pass streaming 
from external network to my home lan using M3U list and HTTP interface 
to control which channel is going to be streamed.

I had used M3U file like this (which I guess I created on windows):

> #EXTM3U
> #EXTVLCOPT:sout=#std{access=udp,dst=225.1.1.1:1234}
> udp://@239.2.3.100:2314
> #EXTVLCOPT:sout=#std{access=udp,dst=225.1.1.1:1234}
> udp://@239.2.3.101:2314
> #EXTVLCOPT:sout=#std{access=udp,dst=225.1.1.1:1234}
> udp://@239.2.3.111:2314
> #EXTVLCOPT:sout=#std{access=udp,dst=225.1.1.1:1234}
> udp://@239.2.3.102:2314
> #EXTVLCOPT:sout=#std{access=udp,dst=225.1.1.1:1234}
> udp://@239.2.3.121:2314
> #EXTVLCOPT:sout=#std{access=udp,dst=225.1.1.1:1234}
> udp://@239.2.3.103:2314

and then run vlc with:
vlc -vv --extraintf http channels.m3u

Now, I got "unsafe option "sout" has been ignored for security reasons", 
in log and although it seems I can switch channels in HTTP interface, 
nothing is apparently streamed.

I wonder, how I am supposed to configure vlc to get the former 
functionality and which security measures are actually violated in my 
scenario.
