[Bro] NUL-related error messages

[Peter Wurzinger]

Hi!

In my notice.log files i frequently find the following two error messages:

run-time error: string with embedded NUL
run-time error: string without NUL terminator

I cannot give specific information about what packets trigger these 
errors, but it seems that often it is NetBios. I am running Bro 1.4.

What could be the problem that causes the errors, and how could I avoid 
them? Do these errors have an impact on signature matching (or other Bro 
functionality)?

Peter.
