New! Plugin Severity Now Using CVSS v3

Synopsis

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

Description

Bryan Call reports :

ATS is vulnerable to certain types of HTTP/2 HEADERS frames that can cause the server to allocate a large amount of memory and spin the thread.

Solution

Update the affected package.
