Synopsis

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

Description

By specially crafting HTTP requests, the mod_md challenge handler would dereference a NULL pointer and cause the child process to segfault. This could be used to DoS the server. Fixed in Apache HTTP Server 2.4.34 (Affected 2.4.33). (CVE-2018-8011)

Run 'yum update httpd' to update your system.
