OpenSSH before 9.6 and many other products, allows remote attackers to
bypass integrity checks such that some packets are omitted (from the
extension negotiation message), and a client and server may consequently
end up with a connection for which some security features have been
downgraded or disabled, aka a Terrapin attack. This occurs because the
SSH Binary Packet Protocol (BPP), implemented by these extensions,
mishandles the handshake phase and mishandles use of sequence numbers.
This update fixes putty.");
