Ubuntu Security Notice USN-3312-1
June 07, 2017
linux, linux-aws, linux-gke, linux-raspi2, linux-snapdragon vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux: Linux kernel
- linux-aws: Linux kernel for Amazon Web Services (AWS) systems
- linux-gke: Linux kernel for Google Container Engine (GKE) systems
- linux-raspi2: Linux kernel for Raspberry Pi 2
- linux-snapdragon: Linux kernel for Snapdragon Processors
Details:
It was discovered that the netfilter netlink implementation in the Linux
kernel did not properly validate batch messages. A local attacker with the
CAP_NET_ADMIN capability could use this to expose sensitive information or
cause a denial of service. (CVE-2016-7917)
Qian Zhang discovered a heap-based buffer overflow in the tipc_msg_build()
function in the Linux kernel. A local attacker could use to cause a denial
of service (system crash) or possibly execute arbitrary code with
administrative privileges. (CVE-2016-8632)
It was discovered that the keyring implementation in the Linux kernel in
some situations did not prevent special internal keyrings from being joined
by userspace keyrings. A privileged local attacker could use this to bypass
module verification. (CVE-2016-9604)
It was discovered that a buffer overflow existed in the trace subsystem in
the Linux kernel. A privileged local attacker could use this to execute
arbitrary code. (CVE-2017-0605)
Dmitry Vyukov discovered that KVM implementation in the Linux kernel
improperly emulated the VMXON instruction. A local attacker in a guest OS
could use this to cause a denial of service (memory consumption) in the
host OS. (CVE-2017-2596)
Daniel Jiang discovered that a race condition existed in the ipv4 ping
socket implementation in the Linux kernel. A local privileged attacker
could use this to cause a denial of service (system crash). (CVE-2017-2671)
Di Shen discovered that a race condition existed in the perf subsystem of
the Linux kernel. A local attacker could use this to cause a denial of
service or possibly gain administrative privileges. (CVE-2017-6001)
Eric Biggers discovered a memory leak in the keyring implementation in the
Linux kernel. A local attacker could use this to cause a denial of service
(memory consumption). (CVE-2017-7472)
Sabrina Dubroca discovered that the asynchronous cryptographic hash (ahash)
implementation in the Linux kernel did not properly handle a full request
queue. A local attacker could use this to cause a denial of service
(infinite recursion). (CVE-2017-7618)
Tuomas Haanpää and Ari Kauppi discovered that the NFSv2 and NFSv3 server
implementations in the Linux kernel did not properly handle certain long
RPC replies. A remote attacker could use this to cause a denial of service
(system crash). (CVE-2017-7645)
Tommi Rantala and Brad Spengler discovered that the memory manager in the
Linux kernel did not properly enforce the CONFIG_STRICT_DEVMEM protection
mechanism. A local attacker with access to /dev/mem could use this to
expose sensitive information or possibly execute arbitrary code.
(CVE-2017-7889)
Tuomas Haanpää and Ari Kauppi discovered that the NFSv2 and NFSv3 server
implementations in the Linux kernel did not properly check for the end of
buffer. A remote attacker could use this to craft requests that cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2017-7895)
It was discovered that a use-after-free vulnerability existed in the device
driver for XCeive xc2028/xc3028 tuners in the Linux kernel. A local
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2016-7913)
Vlad Tsyrklevich discovered an integer overflow vulnerability in the VFIO
PCI driver for the Linux kernel. A local attacker with access to a vfio PCI
device file could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2016-9083, CVE-2016-9084)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 16.04 LTS:
linux-image-4.4.0-1014-gke 4.4.0-1014.14
linux-image-4.4.0-1018-aws 4.4.0-1018.27

linux-image-4.4.0-1059-snapdragon 4.4.0-1059.63
linux-image-4.4.0-79-generic 4.4.0-79.100
linux-image-4.4.0-79-generic-lpae 4.4.0-79.100
linux-image-4.4.0-79-lowlatency 4.4.0-79.100
linux-image-4.4.0-79-powerpc-e500mc 4.4.0-79.100
linux-image-4.4.0-79-powerpc-smp 4.4.0-79.100

linux-image-powerpc-e500mc 4.4.0.79.85
linux-image-powerpc-smp 4.4.0.79.85
linux-image-powerpc64-emb 4.4.0.79.85
linux-image-powerpc64-smp 4.4.0.79.85

linux-image-snapdragon 4.4.0.1059.52
linux-image-virtual 4.4.0.79.85
After a standard system update you need to reboot your computer to make
all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
