"The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in
the USN-2497-1 advisory.
Stephen Roettger, Sebastian Krahmer, and Harlan Stenn discovered that NTP incorrectly handled the length
value in extension fields. A remote attacker could use this issue to possibly obtain leaked information,
or cause the NTP daemon to crash, resulting in a denial of service. (CVE-2014-9297)
Stephen Roettger discovered that NTP incorrectly handled ACLs based on certain IPv6 addresses.
(CVE-2014-9298)
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
