DESCRIPTION
* CVE-2018-3639: Speculative Store Bypass information leak.
A hardware sidechannel with speculative stores could allow a malicious,
unprivileged user to leak the contents of privileged memory.
This update enables the speculative store bypass mitigation by default
when supported microcode is loaded and can be manually enabled/disabled
by writing 1/0 to /proc/sys/vm/ksplice_ssbd_control. The
/proc/sys/vm/ksplice_ssbd_status file reports the current mitigation
status.
* CVE-2017-1000410: Information leak in Bluetooth L2CAP messages.
Incorrect handling of short EFS elements in an L2CAP message could allow
an attacker to leak the contents of kernel memory.
* CVE-2018-10323: NULL pointer dereference when converting extents-format to B+tree in XFS filesystem.
A logic error when converting extents-format to B+tree in XFS filesystem
could lead to a NULL pointer dereference. A local attacker could use
this flaw with a crafted XFS image to cause a denial-of-service.
Orabug: 27963576
* 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: 27963530
* CVE-2018-10675: Use-after-free in get_mempolicy due to incorrect reference counting.
A reference count error in the get_mempolicy ioctl implementation can
result in a use-after-free. A local user could use this flaw to
escalate privileges.
Orabug: 27963519
* Denial-of-service in NFS dentry invalidation.
A logic error in dentry invalidation on NFS filesystems can result in
dentrys being incorrectly invalidated. A local user with access to a
filesystem mounted on top of an NFS filesystem can use this flaw to
unmount the filesystem, leading to a denial-of-service.
Orabug: 27870824
* 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: 27677556
* CVE-2018-6927: Integer overflow when re queuing a futex.
A missing check when calling futex system call with "requeue" option could
lead to an integer overflow. A local attacker could use this flaw to
cause a denial-of-service.
Orabug: 27539548
* CVE-2018-5750: Information leak when registering ACPI Smart Battery System driver.
A too verbose printk when registering ACPI Smart Battery System driver
leaks kernel addresses. A local attacker could use this flaw to
leak information about running kernel and facilitate an attack.
Orabug: 27501257
* CVE-2018-5333: NULL pointer dereference when freeing resources in Reliable Datagram Sockets driver.
A missing check when freeing resources in Reliable Datagram Sockets
driver could lead to a NULL pointer dereference. A local attacker could
use this flaw to cause a denial-of-service.

New Ksplice updates for UEKR4 4.1.12 on OL6 and OL7 (ELSA-2018-4126)
Synopsis: ELSA-2018-4126 can now be patched using Ksplice
CVEs: CVE-2017-16939 CVE-2018-3639
Users with Oracle Linux Premier Support can now use Ksplice to patch
against the latest Oracle Linux Security Advisory, ELSA-2018-4126.
INSTALLING THE UPDATES
We recommend that all users of Ksplice Uptrack running UEKR4 4.1.12 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
* Device Mapper encrypted target Support big-endian plain64 IV.
Some encrypted devices store the initialization vector in big endian
byte ordering and require extra kernel support.
Orabug: 28043932
* Single Thread Indirect Branch Predictors enable failure.
Incorrect masking could prevent the STIBP feature of the IA32_SPEC_CTRL
MSR from being set. Guests that used the STIBP feature to mitigate
Spectre v2 would not be fully mitigated.
* Improved fix to CVE-2018-3639: Speculative Store Bypass information leak.
Booting with speculative store bypass mitigation permanently enabled and
IBRS as the Spectre v2 mitigation would cause the SSBD feature to be
disabled when running in user-space and leaving applications
unprotected.
* Improved AMD fix to CVE-2018-3639: Speculative Store Bypass information leak.
The original vendor fix for CVE-2018-3639 did not expose the mitigation
to KVM guests on AMD or correctly handle symmetric multithreading (SMT)
systems.
This update enables the speculative store bypass mitigation full time to
protect guests and SMT systems by default on AMD systems and can be
manually enabled/disable by writing 1/0 to
/proc/sys/vm/ksplice_ssbd_control. The /proc/sys/vm/ksplice_ssbd_status
file reports the current mitigation status.

the ability to administer an IPSEC tunnel could use this flaw to cause a
denial-of-service.
