If a hostname is supplied to tor-resolve which is too long, it will be
silently truncated, resulting in a different hostname lookup:
$ tor-resolve $(python -c 'print("google.com" + "m" * 256)')
If tor-resolve uses SOCKS5, the length is stored in an unsigned char,
which overflows in this case and leads to the hostname "google.com".
As this one is a valid hostname, it returns an address instead of giving
an error due to the invalid supplied hostname.
Tor protects your privacy on the internet by hiding the connection
between your Internet address and the services you use. We believe Tor
is reasonably secure, but please ensure you read the instructions and
configure it properly.
