updates.

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

Alternatively, you can install these updates by running:

DESCRIPTION

* CVE-2016-3157: Xen I/O port access privilege escalation in x86-64.

User mode processes not supposed to be able to access I/O ports may
be granted such permission, potentially resulting in one or more of
in-guest privilege escalation, guest crashes (Denial of Service), or
in-guest information leaks.


* CVE-2015-8767: Denial-of-service in SCTP heartbeat timeout.

Incorrect locking when accepting an SCTP connection during the 4-way
handshake could result in deadlock.  A local user could use this flaw to
block SCTP connections.
