========================================================================== Ubuntu Security Notice USN-3364-1 July 24, 2017
linux, 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-raspi2: Linux kernel for Raspberry Pi 2 - linux-snapdragon: Linux kernel for Snapdragon processors
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)
It was discovered that the Linux kernel did not properly restrict access to /proc/iomem. A local attacker could use this to expose sensitive information. (CVE-2015-8944)
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)
Jann Horn discovered that bpf in Linux kernel does not restrict the output of the print_bpf_insn function. A local attacker could use this to obtain sensitive address information. (CVE-2017-9150)
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-4.4.0-1065-raspi2 4.4.0-1065.73 linux-image-4.4.0-1067-snapdragon 4.4.0-1067.72 linux-image-4.4.0-87-generic 4.4.0-87.110 linux-image-4.4.0-87-generic-lpae 4.4.0-87.110 linux-image-4.4.0-87-lowlatency 4.4.0-87.110 linux-image-4.4.0-87-powerpc-e500mc 4.4.0-87.110 linux-image-4.4.0-87-powerpc-smp 4.4.0-87.110 linux-image-4.4.0-87-powerpc64-emb 4.4.0-87.110 linux-image-4.4.0-87-powerpc64-smp 4.4.0-87.110 linux-image-generic 4.4.0.87.93 linux-image-generic-lpae 4.4.0.87.93 linux-image-lowlatency 4.4.0.87.93 linux-image-powerpc-e500mc 4.4.0.87.93 linux-image-powerpc-smp 4.4.0.87.93 linux-image-powerpc64-emb 4.4.0.87.93 linux-image-powerpc64-smp 4.4.0.87.93 linux-image-raspi2 4.4.0.1065.66 linux-image-snapdragon 4.4.0.1067.60
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.
