The remote Ubuntu 16.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3619-1 advisory.

  - Use-after-free vulnerability in the snd_pcm_info function in the ALSA subsystem in the Linux kernel allows     attackers to gain privileges via unspecified vectors. (CVE-2017-0861)

  - The Linux Kernel 2.6.32 and later are affected by a denial of service, by flooding the diagnostic port     0x80 an exception can be triggered leading to a kernel panic. (CVE-2017-1000407)

  - The acpi_ns_terminate() function in drivers/acpi/acpica/nsutils.c in the Linux kernel before 4.12 does not     flush the operand cache and causes a kernel stack dump, which allows local users to obtain sensitive     information from kernel memory and bypass the KASLR protection mechanism (in the kernel through 4.9) via a     crafted ACPI table. (CVE-2017-11472)

  - A use-after-free vulnerability was found in network namespaces code affecting the Linux kernel before     4.14.11. The function get_net_ns_by_id() in net/core/net_namespace.c does not check for the net::count     value after it has found a peer network in netns_ids idr, which could lead to double free and memory     corruption. This vulnerability could allow an unprivileged local user to induce kernel memory corruption     on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully     ruled out, although it is thought to be unlikely. (CVE-2017-15129)

  - sound/core/seq_device.c in the Linux kernel before 4.13.4 allows local users to cause a denial of service     (snd_rawmidi_dev_seq_free use-after-free and system crash) or possibly have unspecified other impact via a     crafted USB device. (CVE-2017-16528)

  - The check_alu_op function in kernel/bpf/verifier.c in the Linux kernel through 4.4 allows local users to     cause a denial of service (memory corruption) or possibly have unspecified other impact by leveraging     incorrect sign extension. (CVE-2017-16995)

  - net/netfilter/nfnetlink_cthelper.c in the Linux kernel through 4.14.4 does not require the CAP_NET_ADMIN     capability for new, get, and del operations, which allows local users to bypass intended access     restrictions because the nfnl_cthelper_list data structure is shared across all net namespaces.
    (CVE-2017-17448)

  - The __netlink_deliver_tap_skb function in net/netlink/af_netlink.c in the Linux kernel through 4.14.4,     when CONFIG_NLMON is enabled, does not restrict observations of Netlink messages to a single net     namespace, which allows local users to obtain sensitive information by leveraging the CAP_NET_ADMIN     capability to sniff an nlmon interface for all Netlink activity on the system. (CVE-2017-17449)

  - net/netfilter/xt_osf.c in the Linux kernel through 4.14.4 does not require the CAP_NET_ADMIN capability     for add_callback and remove_callback operations, which allows local users to bypass intended access     restrictions because the xt_osf_fingers data structure is shared across all net namespaces.
    (CVE-2017-17450)

(CVE-2017-17558)

  - The KVM implementation in the Linux kernel through 4.14.7 allows attackers to obtain potentially sensitive     information from kernel memory, aka a write_mmio stack-based out-of-bounds read, related to     arch/x86/kvm/x86.c and include/trace/events/kvm.h. (CVE-2017-17741)

  - The Salsa20 encryption algorithm in the Linux kernel before 4.14.8 does not correctly handle zero-length     inputs, allowing a local attacker able to use the AF_ALG-based skcipher interface     (CONFIG_CRYPTO_USER_API_SKCIPHER) to cause a denial of service (uninitialized-memory free and kernel     crash) or have unspecified other impact by executing a crafted sequence of system calls that use the     blkcipher_walk API. Both the generic implementation (crypto/salsa20_generic.c) and x86 implementation     (arch/x86/crypto/salsa20_glue.c) of Salsa20 were vulnerable. (CVE-2017-17805)

  - The HMAC implementation (crypto/hmac.c) in the Linux kernel before 4.14.8 does not validate that the     underlying cryptographic hash algorithm is unkeyed, allowing a local attacker able to use the AF_ALG-based     hash interface (CONFIG_CRYPTO_USER_API_HASH) and the SHA-3 hash algorithm (CONFIG_CRYPTO_SHA3) to cause a     kernel stack buffer overflow by executing a crafted sequence of system calls that encounter a missing     SHA-3 initialization.

    (CVE-2017-17807)

  - kernel/bpf/verifier.c in the Linux kernel through 4.14.8 ignores unreachable code, even though it would     still be processed by JIT compilers. This behavior, also considered an improper branch-pruning logic     issue, could possibly be used by local users for denial of service. (CVE-2017-17862)

  - crypto/pcrypt.c in the Linux kernel before 4.14.13 mishandles freeing instances, allowing a local user     able to access the AF_ALG-based AEAD interface (CONFIG_CRYPTO_USER_API_AEAD) and pcrypt     (CONFIG_CRYPTO_PCRYPT) to cause a denial of service (kfree of an incorrect pointer) or possibly have     unspecified other impact by executing a crafted sequence of system calls. (CVE-2017-18075)

  - The dm_get_from_kobject function in drivers/md/dm.c in the Linux kernel before 4.14.3 allow local users to     cause a denial of service (BUG) by leveraging a race condition with __dm_destroy during creation and     removal of DM devices. (CVE-2017-18203)

    (CVE-2017-18208)

  - A flaw was found in the Linux kernel before version 4.12 in the way the KVM module processed the trap     flag(TF) bit in EFLAGS during emulation of the syscall instruction, which leads to a debug exception(#DB)     being raised in the guest stack. A user/process inside a guest could use this flaw to potentially escalate     their privileges inside the guest. Linux guests are not affected by this. (CVE-2017-7518)

  - Linux Linux kernel version at least v4.8 onwards, probably well before contains a Insufficient input     validation vulnerability in bnx2x network card driver that can result in DoS: Network card firmware     assertion takes card off-line. This attack appear to be exploitable via An attacker on a must pass a very     large, specially crafted packet to the bnx2x card. This can be done from an untrusted guest VM..
    (CVE-2018-1000026)
