[New-bugs-announce] [issue3830] Tarfile has incorrect USTAR "VERSION" field (should be 00; is 0 NUL)

New submission from SunriseProgrammer <peterdanielsmith at gmail.com>:

The 'tarfile' object make incorrect header blocks.  There's a USTAR 
'MAGIC' string that's supposed to be followed by a version; that version 
is supposed to be two '0' (digit zero -- ascii 48) chars with no NUL 
padding at all.

Python 2.4.3 has it correct.  Later versions (e.g., 2.5) are carefully 
making the field NUL terminated -- but that's wrong; they aren't 
supposed to be.

File History:
'tarfile.py' was correct in version 41340 and incorrect in version 45954
