medium Nessus Plugin ID 86386

Language:

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.

Solution

Update the affected packages.
