Description

A flaw was found in Erlang/OTP kernel. The built-in DNS resolver (inet_res) uses predictable 16-bit transaction IDs and lacks source port randomization. A remote attacker can exploit this by observing or predicting DNS query IDs, leading to DNS cache poisoning. This allows the attacker to redirect network traffic to malicious destinations.
