updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,

DESCRIPTION

* Kernel hang on UDP flood with wrong checksums.

A flaw in the UDP handling of wrong checksums could lead to a kernel hang
under a UDP flood attack.  A remote attacker could use this flaw to cause a
denial-of-service.


* CVE-2015-2922: Denial-of-service of IPv6 networks when handling router advertisements.

A flaw in the IPv6 stack allowed a remote attacker on the same network to
set the hop limit to a smaller value than the default one, preventing
devices on that network to send or receive.
