USN-6738-1: LXD vulnerability

Fabian Bäumer, Marcus Brinkmann, and Jörg Schwenk discovered that LXD
incorrectly handled the handshake phase and the use of sequence numbers in SSH
Binary Packet Protocol (BPP). If a user or an automated system were tricked
into opening a specially crafted input file, a remote attacker could possibly
use this issue to bypass integrity checks.
