  "title": "DNS compression resource exhaustion in gopacket",
  "summary": "gopacket versions before 1.7.5 can consume excessive resources when their DNS decoder processes attacker-controlled compressed DNS names. An unauthenticated remote sender able to reach DNS traffic handled by a gopacket-based decoder can cause denial of service through CPU and, in environments accepting larger messages, memory exhaustion.",
  "mitigation": "Update github.com/gopacket/gopacket to version 1.7.5 or later. Until upgraded, restrict untrusted DNS traffic from reaching processes that decode it with gopacket.",
