Subject: [PATCH] tar: fix 1-byte OOB read in SUN.holesdata parsing

header_pax_extension() passes PAX attribute values without the trailing
newline to pax_attribute(). The SUN.holesdata parser read one byte past
the supplied value when the last numeric field ended at the value
boundary.

Handle length == 0 before checking *e.
