We recommend that all users of Ksplice Uptrack on Ubuntu 15.04 Vivid
install these updates.

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

take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

* CVE-2016-5244: Information leak in the RDS network protocol.

Lack of on-stack struct initialization in the RDS network protocol leads to
one byte of kernel stack being leaked to userspace.  A local attacker could
use this flaw to gain information about the running kernel and facilitate
an attack.


* CVE-2016-5829: Memory corruption in unknown USB HID devices.

The USB HID driver does not validate USB data when an unknown HID device
is encountered which can allow a malicious USB device to trigger kernel
memory corruption and gain execution.


* CVE-2016-5728: Memory corruption in virtio MIC driver.

A race-condition in the virtio MIC host driver can allow a malicious
guest to cause memory corruption in the host when adding a new guest MIC
device.


* CVE-2016-5400: Memory leak in AirSpy SDR device initialization.

A logic error when failing to initialize a AirSpy USB SDR device can
trigger a kernel memory leak and subsequent kernel panic. A local user
with USB access can use this flaw to cause a denial of service.


* CVE-2016-5696: Session hijacking in TCP connections.

A logic error in the core TCP subsystem can allow attackers to easily
guess secret information and inject arbitrary packets into a TCP stream.
