Description
AdGuard Home is a network-wide software for blocking ads and tracking. Prior to 0.107.75, AdGuard Home-s client-triggered DoQ forwarding path to a udp:// upstream reduced backend UDP DNS state by producing dns_id=0 or txid=0 and exposed a quoted-port ICMP source-port oracle, weakening DNS response matching for forwarded queries. This issue is fixed in version 0.107.75.
