[USN-3632-1] Linux kernel (Azure) vulnerabilities

It was discovered that the KVM implementation in the Linux kernel allowed
passthrough of the diagnostic I/O port 0x80. An attacker in a guest VM
could use this to cause a denial of service (system crash) in the host OS.
(CVE-2017-1000407)

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.
