[reSIProcate] Parser validation issues

[Ofir Roval]

Hi all,
 
I came across 2 parsing issues that I would like to share:
 
1. When parsing NameAddr fields, the parser will always accept a header
containing only a STAR sign (*) as valid value. This is of course the
required behavior for Contact header but for headers like From and To I
believe this violates the RFC syntax. Note: other syntax violations will
usually result with an exception.
 
2. When parsing an Interger field like Expires, an integer value greater
that MAX_INT will result in integer-overflow and the actual parsed int
may become a negative number.
 
These issues led me to raise the following question: to what extent is
the parser responsible for ensuring legal syntax ? what do you think ?
