Synopsis

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

Description

The version of avahi installed on the remote host is prior to 0.6.31-20. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2024-2704 advisory.

 avahi: Avahi Wide-Area DNS Uses Constant Source Port (CVE-2024-52615)

 avahi: Avahi Wide-Area DNS Predictable Transaction IDs (CVE-2024-52616)
