The remote Ubuntu 16.04 ESM host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6439-1 advisory.

    It was discovered that the IPv6 implementation in the Linux kernel contained a high rate of hash     collisions in connection lookup table. A remote attacker could use this to cause a denial of service     (excessive CPU consumption). (CVE-2023-1206)

    Yu Hao and Weiteng Chen discovered that the Bluetooth HCI UART driver in the Linux kernel contained a race     condition, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a     denial of service (system crash). (CVE-2023-31083)

    Ross Lagerwall discovered that the Xen netback backend driver in the Linux kernel did not properly handle     certain unusual packets from a paravirtualized network frontend, leading to a buffer overflow. An attacker     in a guest VM could use this to cause a denial of service (host system crash) or possibly execute     arbitrary code. (CVE-2023-34319)

    Lin Ma discovered that the Netlink Transformation (XFRM) subsystem in the Linux kernel contained a null     pointer dereference vulnerability in some situations. A local privileged attacker could use this to cause     a denial of service (system crash). (CVE-2023-3772)

    Kyle Zeng discovered that the networking stack implementation in the Linux kernel did not properly     validate skb object size in certain conditions. An attacker could use this cause a denial of service     (system crash) or possibly execute arbitrary code. (CVE-2023-42752)

    Kyle Zeng discovered that the netfiler subsystem in the Linux kernel did not properly calculate array     offsets, leading to a out-of-bounds write vulnerability. A local user could use this to cause a denial of     service (system crash) or possibly execute arbitrary code. (CVE-2023-42753)

    Kyle Zeng discovered that the IPv4 Resource Reservation Protocol (RSVP) classifier implementation in the     Linux kernel contained an out-of-bounds read vulnerability. A local attacker could use this to cause a     denial of service (system crash). Please note that kernel packet classifier support for RSVP has been     removed to resolve this vulnerability. (CVE-2023-42755)

    Bing-Jhong Billy Jheng discovered that the Unix domain socket implementation in the Linux kernel contained     a race condition in certain situations, leading to a use-after-free vulnerability. A local attacker could     use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-4622)

    Budimir Markovic discovered that the qdisc implementation in the Linux kernel did not properly validate     inner classes, leading to a use-after-free vulnerability. A local user could use this to cause a denial of     service (system crash) or possibly execute arbitrary code. (CVE-2023-4623)

    Alex Birnberg discovered that the netfilter subsystem in the Linux kernel did not properly validate     register length, leading to an out-of- bounds write vulnerability. A local attacker could possibly use     this to cause a denial of service (system crash). (CVE-2023-4881)

    It was discovered that the Quick Fair Queueing scheduler implementation in the Linux kernel did not     properly handle network packets in certain conditions, leading to a use after free vulnerability. A local     attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
    (CVE-2023-4921)

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.
