Description

The remote Ubuntu 16.04 LTS / 18.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-4182-3 advisory.

 USN-4182-1 provided updated Intel Processor Microcode. A regression was discovered that caused some Skylake processors to hang after a warm reboot. This update reverts the microcode for that specific processor family.

 We apologize for the inconvenience.
