Echo: bind9: security update to 1:9.20.29-1~deb13u1

medium Tenable Self-Hosted Container Security Plugin ID 459864

Description

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

 - An attacker may be able to cause a `named` resolver to abort. The attack requires inducing the victim
 resolver to send multiple queries for a DNSSEC-signed zone hosted by an authoritative server under the
 control of the attacker. If the auth responds with a particular sequence of crafted answers, and those
 answers arrive in a particular order with particular timing, the `named` resolver will encounter a use-
 after-free bug, and abort. This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through
 9.20.27, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.27-S1. (CVE-2026-19662)

Solution

Update the bind9 library and its related packages to version 1:9.20.29-1~deb13u1 or later.
