You know as well as I do that not everybody can run the latest
bleeding-edge distro. The reasons are the same as why you would not
recommend end-users make everyday use of the git version of Pulse.

My main concern is that of security, which is the main scenario where
you would want to update to a recent version of Pulse in a "stable"
environment. PulseAudio has not been free of security issues, and yet I
don't know of any "security-only" releases. (Please correct me if I am

If a security issue is discovered in Pulse, affecting several of the
latest versions, and a new version is released to correct the security
hole (as of the time of writing, that would be or 0.9.20), then
what should those running stable distros do?

Obviously we can't update system libraries such as udev, BlueZ, etc.
when we just want the security fix. At the same time, Pulse's current
attitude towards dependencies means running the latest Pulse on the
system without upgrading much of the core will be problematic.

...does not address the security implications of not updating, in which
not updating would lead to compromised systems (e.g. if an Adobe Flash
animation could exploit PulseAudio by playing the audio of a Vista
install disc backwards).

Is there a "best practice" or other tip you can give us to prepare for
these situations in which we really do need to upgrade?
