On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any action.
Alternatively, you can install these updates by running:
# /usr/sbin/uptrack-upgrade -y

Orabug: 28220402
* CVE-2015-8575: Information leak in Bluetooth socket binding.
Lack of input validation when binding a Bluetooth socket could result in
kernel stack memory being leaked to userspace. A local attacker could use
this flaw to gain information about the running kernel.
Orabug: 28130293
* CVE-2018-10124: Denial-of-service when using kill() syscall with a too big pid.
A missing check on user input when using kill() syscall with a pid
number higher than integer limit could lead to an overflow. A local
attacker could use this flaw to cause a denial-of-service.
Orabug: 28082931
* CVE-2018-10087: Denial-of-service when using wait() syscall with a too big pid.
A missing check on user input when using wait() syscall with a pid
number higher than integer limit could lead to an overflow. A local
attacker could use this flaw to cause a denial-of-service.
Orabug: 27875488
* CVE-2018-8781: Integer overflow when mapping memory in USB Display Link video driver.
A missing check on user input when mapping memory in USB Display Link
video driver could lead to an integer overflow. A local attacker could
use this flaw to cause a denial-of-service.
Orabug: 27986407
* CVE-2017-18203: Denial-of-service during device mapper destruction.
A race condition between creation and destruction of device mapper
objects can result in an assertion failure, leading to a kernel crash. A
local user could use this flaw to cause a denial-of-service.
Orabug: 27986397

number higher than integer limit could lead to an overflow. A local
attacker could use this flaw to cause a denial-of-service.
* CVE-2017-18017: Use-after-free when processing TCP packets in netfliter TCPMSS target.
A missing check when using TCPMSS target for TCP could lead to an
use-after-free. A remote attacker could use this flaw to cause a
denial-of-service.
* CVE-2018-5803: Denial-of-service when receiving forged packet over SCTP socket.
A missing check when receiving a forged packet with custom properties
over SCTP socket could lead to a kernel assert. A remote attacker could
use this flaw to cause a denial-of-service.
Orabug: 28240074
* Improved fix to CVE-2018-1093: Denial-of-service in ext4 bitmap block validity check.
Incorrect bitmap range checks could result in bitmap corruption and lost
space on an ext4 filesystem.
