high Tenable Cloud Security Plugin ID 478282

Description

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

 - NLnet Labs ldns 1.2.0 up to and including versions 1.9.0, when used in applications as (stub) resolver
 over UDP, lacks matching the query destination address and port with the response source address and port.
 Furthermore not the query ID, neither the question of the query is matched with that of the response. This
 makes applications, that use ldns for (stub) resolver functionality over UDP, vulnerable for off-path
 poisoning attacks. The drill tool, which is shipped with ldns, suffers from this vulnerability.
 (CVE-2026-10846)

Solution

Update the ldns library and its related packages to version 1.8.4-2+e1 or later.
