New Ksplice updates for UEKR3 3.8.13 on OL6 and OL7 (ELSA-2018-4164)
Synopsis: ELSA-2018-4164 can now be patched using Ksplice
CVEs: CVE-2015-8575 CVE-2017-11600 CVE-2017-18203 CVE-2017-7616 CVE-2018-10087 CVE-2018-10124 CVE-2018-1130 CVE-2018-5803 CVE-2018-8781

Users with Oracle Linux Premier Support can now use Ksplice to patch
against the latest Oracle Linux Security Advisory, ELSA-2018-4164.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running UEKR3 3.8.13 on
OL6 and OL7 install these updates.

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


DESCRIPTION

* CVE-2017-11600: Out-of-bound access in network Transformation user configuration interface.

Orabug: 28240075


* CVE-2018-1130: Denial-of-service in DCCP message send.

A logic error in the dccp code could lead to a NULL pointer dereference
when transmitting messages, leading to a kernel panic. An attacker could
use this to cause a denial-of-service.

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

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.
