Description

The Tor Project reports:

TROVE-2022-002: The SafeSocks option for SOCKS4(a) is inverted leading to SOCKS4 going through

This is a report from hackerone:

We have classified this as medium considering that tor was not defending in-depth for dangerous SOCKS request and so any user relying on SafeSocks 1 to make sure they don't link DNS leak and their Tor traffic wasn't safe afterall for SOCKS4(a).

Tor Browser doesn't use SafeSocks 1 and SOCKS4 so at least the likely vast majority of users are not affected.
