Thanks for the bug report.
I'm closing this bug because it has been fixed in Feisty.
tar 1.16 is in Feisty and from upstream changelog:
2006-08-07 Paul Eggert <[EMAIL PROTECTED]>
* src/incremen.c (read_incr_db_01): Check input strings more
carefully. Do not pass arbitrary char values to isspace, as
this has undefined behavior. Likewise for assigning arbitrary
uintmax_t values to other types.
(read_negative_num, read_unsigned_num, read_timespec):
New functions, to check input values a bit more carefuly.
(read_num): Use read_unsigned_num. New arg MAX_VAL;
all callers changed.
(read_incr_db_2): Use these new functions.
Use a consistent diagnostic for unexpected EOF.
(read_directory_file): Do not assign arbitrary uintmax_t value
to int.
(read_timespec, write_directory_file_entry, write_directory_file):
Handle negative time_t values correctly. We don't bother to do
this with pre-2 formats, since presumably the time stamps were
output incorrectly.
** Changed in: tar (Ubuntu)
Status: Unconfirmed => Fix Released
