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

DESCRIPTION

* CVE-2016-5195: Privilege escalation in copy-on-write memory mappings.

A race condition in the handling of copy-on-write memory mappings could
allow a local, unprivileged user to gain write access to read-only
memory mappings and escalate privileges.


* Denial-of-service in apparmor mount tracking.

A local user that has permissions to mount a filesystem could use
this to potentially crash the system.
