Language:

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

The Apache project reports :

- DoS for HTTP/2 connections by crafted requests (CVE-2018-1333). By specially crafting HTTP/2 requests, workers would be allocated 60 seconds longer than necessary, leading to worker exhaustion and a denial of service. (low)

- mod_md, DoS via Coredumps on specially crafted requests (CVE-2018-8011). 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. (moderate)

Solution

Update the affected package.
