No error message when password is 12 or 1212 (RAR archive)

[kyeastmood]

When I try to list or extract this encrypted RAR archive (v4, locked) using password 12 or 1212 there is no error message and exit code is 0. The real password is different, however I cannot provide it.
With other random passwords like 1, 11, 111, 1111, 13, 1313 the behavior is valid: there is an error message Archive parsing failed! (Attempted to read more data than was available.) and exit code is 1.

Version: 1.10.1/Debian

Thanks

This can be a coincidence, but these passwords are generating pretty valid block type which is treated as 'endBlock` so unarchivation simply ends without any error as if it was an empty archive.
Additional investigation needed.
