FreeBSD : FreeBSD -- Information leak in kldstat(2) (759059ac-dab3-11e7-b5af-a4badb2f4699)

This script is Copyright (C) 2017 Tenable Network Security, Inc.


Synopsis :

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

Description :

The kernel does not properly clear the memory of the kld_file_stat
structure before filling the data. Since the structure filled by the
kernel is allocated on the kernel stack and copied to userspace, a
leak of information from the kernel stack is possible. Impact : Some
bytes from the kernel stack can be observed in userspace.
