FreeBSD : Apache httpd -- denial of service in HTTP/2 (cb0bf1ec-bb92-11e6-a9a5-b499baebfeaf)

Medium Nessus Plugin ID 95586


The remote FreeBSD host is missing one or more security-related updates.


mod_http2 reports :

The Apache HTTPD web server (from 2.4.17-2.4.23) did not apply limitations on request headers correctly when experimental module for the HTTP/2 protocol is used to access a resource.

The net result is that a the server allocates too much memory instead of denying the request. This can lead to memory exhaustion of the server by a properly crafted request.


Update the affected packages.
