[Jamie Iles]

Synopsis: USN-4184-2 can now be patched using Ksplice
CVEs: CVE-2019-0155 CVE-2019-15794 CVE-2019-16746 CVE-2019-19076 CVE-2019-19081 CVE-2019-19523 CVE-2019-19525 CVE-2019-19528

Systems running Ubuntu 19.04 Disco can now use Ksplice to patch
against the latest Ubuntu Security Notice, USN-4184-2.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running Ubuntu 19.04
Disco install these updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

* Improved fix to CVE-2019-0155: Privilege escalation in Intel i915 graphics driver.

The original vendor fix for CVE-2019-0155 did not completely mitigate
the vulnerability for 64-bit systems.  A local unprivileged could use
this flaw to elevate privileges.


* Intel KVM guest creation failure with EPT disabled.

A logic error in masking reserved bits when configuring paging could
result in failing to boot 64-bit guests when Intel EPT was not available
in hardware or disabled by software.
