I can;t imagine what headaches you'd have going from 1.4.11 to 1.4.19.1... that is a minor version upgrade... no real change in functionality.... thats basically 8 versions of bug fixes... if you just apply the IAX2 patch, you'll be fixing 1 out of probably a hundreds of bugs. Going from 1.4.x to 1.6.x however... you'd run into some headaches probably... but if you are staying in the 1.4 series you shouldn;t have any problems... worst case is if its broke you just make install your 1.4.11 overtop of 1.4.19.1 to revert back.

Asterisk Project Security Advisory - AST-2008-006

So given that I'm new to asterisk's svn and bug tracking tool, is it
sufficient then to apply the two patches (iax_dcallno_check-1.2.rev3.txt
and iax_dcallno_check.rev9.txt) listed in
http://bugs.digium.com/view.php?id=10078 to a 1.4.11ish release to
correct this vulnerability? I really don't feel like buying into
any/all of the headaches that went into 1.4.11->1.4.20. You know, "if
it ain't broke don't fix it", and my corollary, "if it is broke, only
fix what's broke, don't try to make it better". Smile

Thanx,
b.

Please understand that that's NOT the only security fix that has gone in
during that time. If this is the only thing that you fix, you're likely
to be vulnerable on several other levels. See our full list of security
disclosures at http://downloads.digium.com/pub/security/

Hrm. Interesting. I don't recall seeing any of those others, such as
AST-2008-005 on this list. Is there some kind of "threat level"
threshold that's applied to what makes the list(s) and what doesn't?

Check the archives. Every single one of the advisories goes out to -users,
-dev, -announce, and -security, along with 4 outside lists (bugtraq, voipsec,
full disclosure, and one other that I can't think of at the moment). The
advisories are also posted at asterisk.org, and I think most of the people who
blog on Asterisk pick up the advisories, as well.

In short, I can't think of a reason why you should be unaware of any security
advisory regarding a past release of Asterisk.
