"The remote Ubuntu 16.04 ESM host has a package installed that is affected by multiple vulnerabilities as referenced in
the USN-5262-1 advisory.
The potential for an out of bounds write due to a missing bounds check was discovered to impact the sgdisk
utility of GPT fdisk.
Exploitation requires the use of a maliciously formatted storage
device and could cause sgdisk to crash as well as possibly
allow for local privilege escalation.
Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
