Synopsis :

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

Description :

ARM Limited reports :

When the client creates its ClientHello message, due to insufficient
bounds checking it can overflow the heap-based buffer containing the
message while writing some extensions. Two extensions in particular
could be used by a remote attacker to trigger the overflow : the
session ticket extension and the server name indication (SNI)
extension.
