medium Nessus Plugin ID 319845

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 multiple vulnerabilities as referenced in the ALAS2-2026-3353 advisory.

 Limit resolver server list size (CVE-2026-3592)

 Avoid unbounded recursion loop (CVE-2026-5950)

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

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

Solution
