Echo: github.com/coredns/coredns: security update to 1.12.4

high Tenable Cloud Security Plugin ID 462390

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- CoreDNS is a DNS server that chains plugins. Starting in version 1.2.0 and prior to version 1.12.4, the
CoreDNS etcd plugin contains a TTL confusion vulnerability where lease IDs are incorrectly used as TTL
values, enabling DNS cache pinning attacks. This effectively creates a DoS condition for DNS resolution of
affected services. The `TTL()` function in `plugin/etcd/etcd.go` incorrectly casts etcd lease IDs (64-bit
integers) to uint32 and uses them as TTL values. Large lease IDs become very large TTLs when cast to
uint32. This enables cache pinning attacks. Version 1.12.4 contains a fix for the issue. (CVE-2025-58063)

Solution

Update the github.com/coredns/coredns library and its related packages to version 1.12.4 or later.
