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-6701-1 advisory.

    Ruihan Li discovered that the bluetooth subsystem in the Linux kernel did not properly perform permissions     checks when handling HCI sockets. A physically proximate attacker could use this to cause a denial of     service (bluetooth communication). (CVE-2023-2002)

    It was discovered that the NVIDIA Tegra XUSB pad controller driver in the Linux kernel did not properly     handle return values in certain error conditions. A local attacker could use this to cause a denial of     service (system crash). (CVE-2023-23000)

    It was discovered that Spectre-BHB mitigations were missing for Ampere processors. A local attacker could     potentially use this to expose sensitive information. (CVE-2023-3006)

    It was discovered that the ext4 file system implementation in the Linux kernel did not properly handle     block device modification while it is mounted. A privileged attacker could use this to cause a denial of     service (system crash) or possibly expose sensitive information. (CVE-2023-34256)

    Eric Dumazet discovered that the netfilter subsystem in the Linux kernel did not properly handle DCCP     conntrack buffers in certain situations, leading to an out-of-bounds read vulnerability. An attacker could     possibly use this to expose sensitive information (kernel memory). (CVE-2023-39197)

    It was discovered that the Siano USB MDTV receiver device driver in the Linux kernel did not properly     handle device initialization failures in certain situations, leading to a use-after-free vulnerability. A     physically proximate attacker could use this cause a denial of service (system crash). (CVE-2023-4132)

    Pratyush Yadav discovered that the Xen network backend implementation in the Linux kernel did not properly     handle zero length data request, leading to a null pointer dereference vulnerability. An attacker in a     guest VM could possibly use this to cause a denial of service (host domain crash). (CVE-2023-46838)

    It was discovered that a race condition existed in the AppleTalk networking subsystem of the Linux kernel,     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-2023-51781)

    Alon Zahavi discovered that the NVMe-oF/TCP subsystem of the Linux kernel did not properly handle connect     command payloads in certain situations, leading to an out-of-bounds read vulnerability. A remote attacker     could use this to expose sensitive information (kernel memory). (CVE-2023-6121)

    It was discovered that the ext4 file system implementation in the Linux kernel did not properly handle the     remount operation in certain cases, leading to a use-after-free vulnerability. A local attacker could use     this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2024-0775)

    Notselwyn discovered that the netfilter subsystem in the Linux kernel did not properly handle verdict     parameters in certain cases, 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-2024-1086)

    It was discovered that a race condition existed in the SCSI Emulex LightPulse Fibre Channel driver in the     Linux kernel when unregistering FCF and re-scanning an HBA FCF table, leading to a null pointer     dereference vulnerability. A local attacker could use this to cause a denial of service (system crash).
    (CVE-2024-24855)

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.
