Summary

miekg/dns insecurely generates random numbers

Details

The miekg Go DNS package before 1.1.25, as used in CoreDNS before 1.6.6 and other products, improperly generates random numbers because math/rand is used. The TXID becomes predictable, leading to response forgeries.

Severity

5.9 (Medium)
