    CVE-2019-19794

    Published: 13 Dec 2019Last Modified: 8 Jul 2026

    Summary:

    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.
