lzma_str_to_filters() may call parse_lzma12_preset() in two ways. The
call from str_to_filters() detects the string type from the first
character(s) and as a side-effect it validates the first digit of
the preset string. So this change makes no difference there.
However, the call from parse_options() doesn't pre-validate the string.
parse_lzma12_preset() will return an invalid value which is passed to
lzma_lzma_preset() which safely rejects it. The bug still affects the
the error message:
$ xz --filters=lzma2:preset=X
xz: Error in --filters=FILTERS option:
xz: lzma2:preset=X
xz: ^
xz: Unsupported preset
After the fix:
$ xz --filters=lzma2:preset=X
xz: Error in --filters=FILTERS option:
xz: lzma2:preset=X
xz: ^
xz: Unsupported preset
The ^ now correctly points to the X and not past it because the X itself
is the problematic character.
