Summary:                    Dialplan language does not deal with & character
safely
Description: 
The dialplan language uses the & character to represent arrays. For example
123&456&789 is an array of three elements 123, 456 and 789. However the
dialplan language does not prohibit (or escape) the use of a & character in
an array element. This means that the content of an element can cause the
execution of code when passed to a function (in this case the creation of a
new element)
