INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running Ubuntu 14.04
Trusty 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-2014-9900: Information disclosure in Wake-On-LAN driver.

Due to a failure to correctly clear memory, sensitive kernel information
can be disclosed to userspace when information about Wake-On-LAN support
is requested. A local attacker could use this flaw to facilitate a
further attack on the kernel.


* CVE-2017-9074: Denial-of-service when using Generic Segmentation Offload on IPV6 socket.

A missing check when using Generic Segmentation Offload on IPV6 socket
could lead to a memory leak. A local attacker could use this flaw to cause
a denial-of-service.


* CVE-2015-8963: Privilege escalation in the perf sub-system on CPU unplug.

A race condition when hashing a software event in the perf sub-system could
lead to a use-after-free and kernel panic.  A local user with the ability
to cause CPU unplug could potentially use this flaw to elevate its
privileges.


* CVE-2015-8962: Privilege escalation when detaching SCSI drives.

A double free flaw when detaching an SCSI drive on concurrent DMA
operations could lead to memory corruptions and kernel panic.  A local user
with the ability to detach an SCSI drive could potentially use this flaw to
elevate its privileges.


* CVE-2015-8964: Use-after-free in tty line discipline configuration.

Incorrect initialization in the tty subsystem can cause a tty driver to
access previously freed memory. A local attacker could use this to
obtain sensitive information from the kernel.


* CVE-2017-8924: Information leak in Digi Edgeport TI callback completion.

An integer underflow in the Digi Edgeport TI USB driver can allow a malicious
USB device to leak the contents of kernel memory to userspace.


* CVE-2017-7346: Denial-of-service when user defines surface in VMware Virtual GPU driver.

A missing check on user input could lead to an infinite loop. A local
attacker could use this flaw to cause a denial-of-service.


* CVE-2016-10088: Privilege escalation in SCSI device interface.

Incorrect validation when writing to an sg device can result in the
ability to read and write to kernel memory. A local attacker with access
to /dev/sg* devices could use this flaw to escalate privileges.


* CVE-2017-1000380: Information leak when reading timer information from ALSA devices.

A missing data initialization and a race condition when reading timer
information of ALSA devices from user space could lead to an information
leak. A local attacker could use this flaw to get information about
running kernel and facilitate an attack.


* CVE-2017-9605: Information leak when user defines surface in VMware Virtual GPU driver.

A missing initialization of local variable when user defines surface in
VMXGFX driver could leak stack information. A local attacker could use
this flaw to gain information about the running kernel and facilitate an
attack.


* CVE-2017-7895: Remote information leak in kernel NFS server.

Missing bounds checks could result in an out-of-bounds memory access,
allowing a remote attacker to leak the contents of kernel memory.


* CVE-2015-8944: Information disclosure via /proc/iomem.

A failure to correctly check permissions can lead to sensitive addresses
being disclosed from /proc/iomem. A local attacker could use this flaw
to facilitate a further attack on the kernel.


* CVE-2017-8925: Memory leak when opening an Omninet serial driver.

An extra reference on the TTY was taken in the Omninet serial driver on
open, leading to a memory leak.  A local, unprivileged user could use this
flaw to exhaust the memory on the system and cause a denial-of-service.
