Ubuntu Security Notice USN-3358-1
20th July, 2017
linux, linux-raspi2 vulnerabilities
A security issue affects these releases of Ubuntu and its
- Ubuntu 17.04
Several security issues were fixed in the Linux kernel.
– Linux kernel
– Linux kernel for Raspberry Pi 2
It was discovered that the Linux kernel did not properly initialize a Wake-
on-Lan data structure. A local attacker could use this to expose sensitive
information (kernel memory). (CVE-2014-9900)
Alexander Potapenko discovered a race condition in the Advanced Linux Sound
Architecture (ALSA) subsystem in the Linux kernel. A local attacker could
use this to expose sensitive information (kernel memory).
Li Qiang discovered that the DRM driver for VMware Virtual GPUs in the
Linux kernel did not properly validate some ioctl arguments. A local
attacker could use this to cause a denial of service (system crash).
Murray McAllister discovered that the DRM driver for VMware Virtual GPUs in
the Linux kernel did not properly initialize memory. A local attacker could
use this to expose sensitive information (kernel memory). (CVE-2017-9605)
The problem can be corrected by updating your system to the following
- Ubuntu 17.04:
- linux-image-generic-lpae 188.8.131.52.29
- linux-image-generic 184.108.40.206.29
- linux-image-lowlatency 220.127.116.11.29
- linux-image-raspi2 18.104.22.1681.13
To update your system, please follow these instructions:
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.
