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.
