high Tenable Self-Hosted Container Security Plugin ID 438473

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)
