The remote Ubuntu 16.04 ESM host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6532-1 advisory.

    Tavis Ormandy discovered that some AMD processors did not properly handle speculative execution of certain     vector register instructions. A local attacker could use this to expose sensitive information.
    (CVE-2023-20593)

    Yu Hao discovered that the UBI driver in the Linux kernel did not properly check for MTD with zero     erasesize during device attachment. A local privileged attacker could use this to cause a denial of     service (system crash). (CVE-2023-31085)

    Lucas Leong discovered that the netfilter subsystem in the Linux kernel did not properly validate some     attributes passed from userspace. A local attacker could use this to cause a denial of service (system     crash) or possibly expose sensitive information (kernel memory). (CVE-2023-39189)

    Sunjoo Park discovered that the netfilter subsystem in the Linux kernel did not properly validate u32     packets content, leading to an out-of-bounds read vulnerability. A local attacker could use this to cause     a denial of service (system crash) or possibly expose sensitive information. (CVE-2023-39192)

    Lucas Leong discovered that the netfilter subsystem in the Linux kernel did not properly validate SCTP     data, leading to an out-of-bounds read vulnerability. A local attacker could use this to cause a denial of     service (system crash) or possibly expose sensitive information. (CVE-2023-39193)

    Lucas Leong discovered that the Netlink Transformation (XFRM) subsystem in the Linux kernel did not     properly handle state filters, leading to an out- of-bounds read vulnerability. A privileged local     attacker could use this to cause a denial of service (system crash) or possibly expose sensitive     information. (CVE-2023-39194)

    Kyle Zeng discovered that the IPv4 implementation in the Linux kernel did not properly handle socket     buffers (skb) when performing IP routing in certain circumstances, leading to a null pointer dereference     vulnerability. A privileged attacker could use this to cause a denial of service (system crash).
    (CVE-2023-42754)

    It was discovered that the USB ENE card reader driver in the Linux kernel did not properly allocate enough     memory when processing the storage device boot blocks. A local attacker could use this to cause a denial     of service (system crash). (CVE-2023-45862)

    Manfred Rudigier discovered that the Intel(R) PCI-Express Gigabit (igb) Ethernet driver in the Linux     kernel did not properly validate received frames that are larger than the set MTU size, leading to a     buffer overflow vulnerability. An attacker could use this to cause a denial of service (system crash) or     possibly execute arbitrary code. (CVE-2023-45871)

    Budimir Markovic discovered that the perf subsystem in the Linux kernel did not properly handle event     groups, leading to an out-of-bounds write vulnerability. A local attacker could use this to cause a denial     of service (system crash) or possibly execute arbitrary code. (CVE-2023-5717)

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.
