========================================================================== Ubuntu Security Notice USN-3371-1 July 28, 2017
linux-hwe 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-hwe: Linux hardware enablement (HWE) kernel
Details:
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). (CVE-2017-1000380)
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). (CVE-2017-7346)
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)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.04 LTS: linux-image-4.10.0-28-generic 4.10.0-28.32~16.04.2 linux-image-4.10.0-28-generic-lpae 4.10.0-28.32~16.04.2 linux-image-4.10.0-28-lowlatency 4.10.0-28.32~16.04.2 linux-image-generic-hwe-16.04 4.10.0.28.31 linux-image-generic-lpae-hwe-16.04 4.10.0.28.31 linux-image-lowlatency-hwe-16.04 4.10.0.28.31
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.
