Amazon Linux 2023: CVE-2025-53859: Low priority package update for nginx

A memory access flaw has been discovered in nginx. The ngx_mail_smtp_module might allow an unauthenticated attacker to over-read NGINX SMTP authentication process memory. As a result, the server side may leak arbitrary bytes sent in a request to the authentication server. This issue occurs during the NGINX SMTP authentication process, requiring the attacker to prepare against the target system to extract the leaked data.
