Re: [Xen-devel] Security policy ambiguities - XSA-108 process post-mortem

Hi all,
I am assuming this question is in effect resolved. The proposed (and agreed) 
text basically states that security advisories state whether people will be 
allowed to deploy. The underlying assumption is that usually this is the case, 
unless there is a very good reason not to. How the security team handles these 
does not really need to be codified and could be based on whether the 
deployment would allow reverse engineering the issue (this would be very rare) 
and thus put everyone at risk, the discoverer stating that he/she not wanting a 
deployment, or any other reasons.
