    netscaler: fix multiple out-of-bounds reads.
    
    Multiple bugs have been found in the provided bug. Some of them have
    been fixed in gefe920a, others here. The main problem is when malformed
    files give wrong lenghts to the code, that casts and dereference it
    without checking, causing oob reads. The fix introduces a check function
    that prevents to go beyond the limits, early returning with a malformed
    file message.
    
    Other bugs have been fixed by forcing the string terminator that allows
    the use of strlen() and MIN() that prevent wrong reads.
