The remote Ubuntu 16.04 LTS / 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4185-1 advisory.
Improper invalidation for page table updates by a virtual guest operating system for multiple Intel® Processors may allow an authenticated user to potentially enable denial of service of the host system via local access. (CVE-2018-12207)
Insufficient access control in subsystem for Intel ® processor graphics in 6th, 7th, 8th and 9th Generation Intel® Core™ Processor Families; Intel® Pentium® Processor J, N, Silver and Gold Series; Intel® Celeron® Processor J, N, G3900 and G4900 Series; Intel® Atom® Processor A and E3900 Series; Intel® Xeon® Processor E3-1500 v5 and v6 and E-2100 Processor Families may allow an authenticated user to potentially enable denial of service via local access. (CVE-2019-0154)

(CVE-2019-0155)
TSX Asynchronous Abort condition on some CPUs utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access. (CVE-2019-11135)
drivers/net/wireless/ath/ath6kl/usb.c in the Linux kernel through 5.2.9 has a NULL pointer dereference via an incomplete address in an endpoint descriptor. (CVE-2019-15098)
ax25_create in net/ax25/af_ax25.c in the AF_AX25 network module in the Linux kernel 3.16 through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka CID-0614e2b73768. (CVE-2019-17052)
ieee802154_create in net/ieee802154/socket.c in the AF_IEEE802154 network module in the Linux kernel through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka CID-e69dbd4619e7. (CVE-2019-17053)
atalk_create in net/appletalk/ddp.c in the AF_APPLETALK network module in the Linux kernel through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka CID-6cc03e8aa36c. (CVE-2019-17054)
base_sock_create in drivers/isdn/mISDN/socket.c in the AF_ISDN network module in the Linux kernel through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka CID-b91ee4aa2a21. (CVE-2019-17055)
llcp_sock_create in net/nfc/llcp_sock.c in the AF_NFC network module in the Linux kernel through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka CID-3a359798b176. (CVE-2019-17056)
rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux kernel through 5.3.6 lacks a certain upper-bound check, leading to a buffer overflow. (CVE-2019-17666)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
