Ubuntu Security Notice USN-3680-1
June 12, 2018

libvirt vulnerability and update
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

– Ubuntu 18.04 LTS
– Ubuntu 17.10
– Ubuntu 16.04 LTS
– Ubuntu 14.04 LTS

Summary:

Side channel execution mitigations were added to libvirt.

Software Description:
– libvirt: Libvirt virtualization toolkit

Details:

Ken Johnson and Jann Horn independently discovered that microprocessors
utilizing speculative execution of a memory read may allow unauthorized
memory reads via sidechannel attacks. An attacker in the guest could use
this to expose sensitive guest information, including kernel memory. This
update allows libvirt to expose new CPU features added by microcode updates
to guests. (CVE-2018-3639)

Daniel P. Berrange discovered that libvirt incorrectly handled the QEMU
guest agent. An attacker could possibly use this issue to consume
resources, leading to a denial of service. (CVE-2018-1064)

Update instructions:

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

Ubuntu 18.04 LTS:
libvirt-bin 4.0.0-1ubuntu8.2
libvirt0 4.0.0-1ubuntu8.2

Ubuntu 17.10:
libvirt-bin 3.6.0-1ubuntu6.8
libvirt0 3.6.0-1ubuntu6.8

Ubuntu 16.04 LTS:
libvirt-bin 1.3.1-1ubuntu10.24
libvirt0 1.3.1-1ubuntu10.24

Ubuntu 14.04 LTS:
libvirt-bin 1.2.2-0ubuntu13.1.27
libvirt0 1.2.2-0ubuntu13.1.27

After a standard system update you need to reboot your computer to make
all the necessary changes.
