Review request for Asterisk Developers and Mark Michelson.


Summary
-------

I was a bit quick on the ship-it there ;)
Those strdupa's are far from safe from direct user input.

Here's a fix, which happens to slightly faster too.


Diffs

Testing
-------

Got asterisk to crash easily before patch. No crash after. Mark's test from r2123 still completes with 0 errors.


Thanks,

wdoekes
