GNU tar 1.11.2
>Description:
The '-I' option of tar is used to specify a file containing a list
of files to create/extract. Whilst the option parsing code expects
'-I' to take an option, the string passed to getoldopts() specifies
that '-I' doesn't take an option. This leads to NULL being passed
to strcmp().
>How-To-Repeat:
echo "/bin" >/tmp/foo
tar -cf /dev/null -I /tmp/foo
>Fix:
Index: tar.c
