Amazon Linux 2 : bind (ALAS-2024-2625)

high Nessus Plugin ID 206022

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of bind installed on the remote host is prior to 9.11.4-26.P2. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2625 advisory.

 The DNS message parsing code in `named` includes a section whose computational complexity is overly high.
 It does not cause problems for typical DNS traffic, but crafted queries and responses may cause excessive CPU load on the affected `named` instance by exploiting this flaw. This issue affects both authoritative servers and recursive resolvers.This issue affects BIND 9 versions 9.0.0 through 9.16.45, 9.18.0 through 9.18.21, 9.19.0 through 9.19.19, 9.9.3-S1 through 9.11.37-S1, 9.16.8-S1 through 9.16.45-S1, and 9.18.11-S1 through 9.18.21-S1. (CVE-2023-4408)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update bind' to update your system.
