install these updates.

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

Alternatively, you can install these updates by running:

DESCRIPTION

* Improved fix to CVE-2015-8543: Denial-of-service on out of range protocol for raw sockets.

The original vendor fix for CVE-2015-8543 has been extended to cover
additional network protocols.


* Improve fix for CVE-2015-7513: Divide-by-zero in KVM when reloading the programmable interrupt timer.

A missing input sanitization when loading the programmable interrupt timer
counters from userspace could cause KVM to make a division by zero, causing
a kernel crash.  A local user with the capability to run KVM machines could
use this flaw to cause a denial-of-service.


* CVE-2016-2383: Undefined behaviour in Berkeley Packet Filter constant shifts.

Missing validation of constant shifts in a BPF program could result in
undefined behaviour, depending on the system.


* CVE-2015-2085: Timing side channel attack in EVM integrity module.

The verification routine of the EVM HMAC was using a regular non-constant
memcmp(), allowing attackers to do timing side channel attacks and reduce
the MAC forgery complexity from 2^128 to 2^12.


* CVE-2015-7833: Data loss in USB Modem driver during suspend and resume.

Improper cleanup in the USB Modem driver leads to data loss during a
suspend and resume sequence.
