Kernel/Berkeley DB Updates for Ubuntu
Posted on: 11/22/2017 05:26 AM

The following updates has been released for Ubuntu Linux:

USN-3484-3: Linux kernel (GCP) vulnerability
USN-3485-3: Linux kernel (AWS) vulnerabilities
USN-3487-1: Linux kernel vulnerabilities
USN-3488-1: Linux kernel (Azure) vulnerability
USN-3489-1: Berkeley DB vulnerability
USN-3489-2: Berkeley DB vulnerability

USN-3484-3: Linux kernel (GCP) vulnerability


=========================================================================
Ubuntu Security Notice USN-3484-3
November 21, 2017

linux-gcp vulnerability
=========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 16.04 LTS

Summary:

The system could be made to crash or run programs as an administrator.

Software Description:
- linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems

Details:

It was discovered that the KVM subsystem in the Linux kernel did not
properly keep track of nested levels in guest page tables. A local attacker
in a guest VM could use this to cause a denial of service (host OS crash)
or possibly execute arbitrary code in the host OS.

Update instructions:

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

Ubuntu 16.04 LTS:
linux-image-4.10.0-1009-gcp 4.10.0-1009.9
linux-image-gcp 4.10.0.1009.11

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.
