[Asterisk-Users] Security Vulnerability in Asterisk

[Michael Sandee]

It kind of seems to be the policy of... <asterisk maintainer(s)> to not 
disclose anything to the public and silently update it..
I didn't want to make a fuss about it (again)... but now it's on the ML 
anyway...

This type of "elitist" behaviour REALLY sucks...

I hope in the future announcements will be made on this type of 
problems... Yeah I was still running a system with an old version of 
asterisk/iax on the public internet when I saw this on bugtraq... 
Because it simply worked...

Other than that... if these problems are not being published when 
fixed... then other distro's do not have a chance to fix it... (think 
about distro's that use "stable" code, but haven't updated to 0.9 
because of problems)

Common people... this is far worse behaviour than Microsoft's policy on 
bugs... atleast they have *some* form of public disclosure...
