NGINX: NGINX: Denial of Service via undisclosed requests when ngx_mail_auth_http_module is enabled

A flaw was found in NGINX, specifically within the ngxmailauthhttpmodule. When this module is enabled, and CRAM-MD5 or APOP authentication is active with an authentication server that permits retries, undisclosed requests can cause NGINX worker processes to terminate. This can lead to a Denial of...
