Indeni considers this vulnerability as a low severity issue due to the fact that all Indeni servers are located behind firewalls that are meant to prevent access to them by hackers. However, it's best practice to patch your system regardless of where the Indeni system resides.

Please Note: There have been reports that kernel image 4.4.0-108 will cause Ubuntu to no longer load, but has been resolved on 4.4.0-109. We are currently testing this, so do not update your indeni server until we confirm continued functionality on the latest kernel image.
