Amazon Linux 2 : bind, --advisory ALAS2-2025-3093 (ALAS-2025-3093)

high Nessus Plugin ID 277750

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 ALAS2-2025-3093 advisory.

 Under certain circumstances, BIND is too lenient when accepting records from answers, allowing an attacker to inject forged data into the cache.This issue affects BIND 9 versions 9.11.0 through 9.16.50, 9.18.0 through 9.18.39, 9.20.0 through 9.20.13, 9.21.0 through 9.21.12, 9.11.3-S1 through 9.16.50-S1, 9.18.11-S1 through 9.18.39-S1, and 9.20.9-S1 through 9.20.13-S1. (CVE-2025-40778)

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' or or 'yum update --advisory ALAS2-2025-3093' to update your system.
