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)

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-2017-17806)

  • The KEYS subsystem in the Linux kernel before 4.14.6 omitted an access-control check when adding a key to the current task’s default request-key keyring via the request_key() system call, allowing a local user to use a sequence of crafted system calls to add keys to a keyring with only Search permission (not Write permission) to that keyring, related to construct_get_dest_keyring() in security/keys/request_key.c.
    (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)

  • 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)

  • In the Linux kernel through 3.2, the rds_message_alloc_sgs() function does not validate a value that is used during DMA page allocation, leading to a heap-based out-of-bounds write (related to the rds_rdma_extra_size function in net/rds/rdma.c). (CVE-2018-5332)

  - 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)

  - In the Linux kernel through 3.2, the rds_message_alloc_sgs() function does not validate a value that is
    used during DMA page allocation, leading to a heap-based out-of-bounds write (related to the
    rds_rdma_extra_size function in net/rds/rdma.c). (CVE-2018-5332)

  - In the Linux kernel through 4.14.13, the rds_cmsg_atomic function in net/rds/rdma.c mishandles cases where
    page pinning fails or an invalid address is supplied, leading to an rds_atomic_free_op NULL pointer
    dereference. (CVE-2018-5333)

  - In the Linux kernel through 4.14.13, drivers/block/loop.c mishandles lo_release serialization, which
    allows attackers to cause a denial of service (__lock_acquire use-after-free) or possibly have unspecified
    other impact. (CVE-2018-5344)

  - The futex_requeue function in kernel/futex.c in the Linux kernel before 4.14.15 might allow attackers to
    cause a denial of service (integer overflow) or possibly have unspecified other impact by triggering a
    negative wake or requeue value. (CVE-2018-6927)

  - A NULL pointer dereference was found in the net/rds/rdma.c __rds_rdma_map() function in the Linux kernel
    before 4.14.7 allowing local attackers to cause a system panic and a denial-of-service, related to
    RDS_GET_MR and RDS_GET_MR_FOR_DEST. (CVE-2018-7492)

  - The unimac_mdio_probe function in drivers/net/phy/mdio-bcm-unimac.c in the Linux kernel through 4.15.8
    does not validate certain resource availability, which allows local users to cause a denial of service
    (NULL pointer dereference). (CVE-2018-8043)
