Would SELinux prevent that with the current policy?

[Christoph Höger]

Hi,

after looking at:
http://blog.cr0.org/2009/07/old-school-local-root-vulnerability-in.html

I wondered if SELinux would not be the right answer to those re-exec
exploits. I guess that pulseaudio should run as something like
pulseaudio_t which has all caps it needs. 
Re-exec should not change that as pulseaudio does not need any
transformation of context. 

So short question: Does it work that way?
