Description

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

- CoreDNS is a DNS server that chains plugins. Prior to version 1.14.2, a denial of service vulnerability
exists in CoreDNS's loop detection plugin that allows an attacker to crash the DNS server by sending
specially crafted DNS queries. The vulnerability stems from the use of a predictable pseudo-random number
generator (PRNG) for generating a secret query name, combined with a fatal error handler that terminates
the entire process. This issue has been patched in version 1.14.2. (CVE-2026-26018)

Solution

Update the github.com/coredns/coredns library and its related packages to version 1.14.2 or later.
