Ubuntu Security Notice USN-3293-1
May 17, 2017

linux, linux-raspi2 vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 17.04

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux: Linux kernel
- linux-raspi2: Linux kernel for Raspberry Pi 2

Details:

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)

Dmitry Vyukov discovered that the generic SCSI (sg) subsystem in the Linux
kernel contained a stack-based buffer overflow. A local attacker with
access to an sg device could use this to cause a denial of service (system
crash) or possibly execute arbitrary code. (CVE-2017-7187)

It was discovered that a NULL pointer dereference existed in the Direct
Rendering Manager (DRM) driver for VMWare devices in the Linux kernel. A
local attacker could use this to cause a denial of service (system crash).
(CVE-2017-7261)

Li Qiang discovered that an integer overflow vulnerability existed in the
Direct Rendering Manager (DRM) driver for VMWare devices in the Linux
kernel. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2017-7294)

Jason Donenfeld discovered a heap overflow in the MACsec module in the
Linux kernel. An attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2017-7477)

It was discovered that an information leak existed in the set_mempolicy and
mbind compat syscalls in the Linux kernel. A local attacker could use this
to expose sensitive information (kernel memory). (CVE-2017-7616)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 17.04:
linux-image-4.10.0-1005-raspi2 4.10.0-1005.7
linux-image-4.10.0-21-generic 4.10.0-21.23
linux-image-4.10.0-21-generic-lpae 4.10.0-21.23
linux-image-4.10.0-21-lowlatency 4.10.0-21.23
linux-image-generic 4.10.0.21.23
linux-image-generic-lpae 4.10.0.21.23
linux-image-lowlatency 4.10.0.21.23
linux-image-raspi2 4.10.0.1005.7

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.
