The remote NewStart CGSL host, running version MAIN 4.05, has kernel packages installed that are affected by multiple vulnerabilities:

  - 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)

  - Improper invalidation for page table updates by a     virtual guest operating system for multiple Intel(R)     Processors may allow an authenticated user to     potentially enable denial of service of the host system     via local access. (CVE-2018-12207)

  - An issue was discovered in the proc_pid_stack function     in fs/proc/base.c in the Linux kernel through 4.18.11.
    It does not ensure that only root may inspect the kernel     stack of an arbitrary task, allowing a local attacker to     exploit racy stack unwinding and leak kernel task stack     contents. (CVE-2018-17972)

  - In sk_clone_lock of sock.c, there is a possible memory     corruption due to type confusion. This could lead to     local escalation of privilege with no additional     execution privileges needed. User interaction is not     needed for exploitation. Product: Android. Versions:
    Android kernel. Android ID: A-113509306. References:
    Upstream kernel. (CVE-2018-9568)

  - Insufficient access control in subsystem for Intel (R)     processor graphics in 6th, 7th, 8th and 9th Generation     Intel(R) Core(TM) Processor Families; Intel(R)     Pentium(R) Processor J, N, Silver and Gold Series;
    Intel(R) Celeron(R) Processor J, N, G3900 and G4900     Series; Intel(R) Atom(R) Processor A and E3900 Series;
    Intel(R) Xeon(R) Processor E3-1500 v5 and v6 and E-2100     Processor Families may allow an authenticated user to     potentially enable denial of service via local access.
    (CVE-2019-0154)

  - Insufficient access control in a subsystem for Intel (R)     processor graphics in 6th, 7th, 8th and 9th Generation     Intel(R) Core(TM) Processor Families; Intel(R)     Pentium(R) Processor J, N, Silver and Gold Series;
    Intel(R) Celeron(R) Processor J, N, G3900 and G4900     Series; Intel(R) Atom(R) Processor A and E3900 Series;
    Intel(R) Xeon(R) Processor E3-1500 v5 and v6, E-2100 and     E-2200 Processor Families; Intel(R) Graphics Driver for     Windows before 26.20.100.6813 (DCH) or 26.20.100.6812     and before 21.20.x.5077 (aka15.45.5077), i915 Linux     Driver for Intel(R) Processor Graphics before versions     5.4-rc7, 5.3.11, 4.19.84, 4.14.154, 4.9.201, 4.4.201 may     allow an authenticated user to potentially enable     escalation of privilege via local access.
    (CVE-2019-0155)

  - TSX Asynchronous Abort condition on some CPUs utilizing     speculative execution may allow an authenticated user to     potentially enable information disclosure via a side     channel with local access. (CVE-2019-11135)

  - An information disclosure vulnerability exists when     certain central processing units (CPU) speculatively     access memory, aka 'Windows Kernel Information     Disclosure Vulnerability'. This CVE ID is unique from     CVE-2019-1071, CVE-2019-1073. (CVE-2019-1125)

  - An issue was discovered in the Linux kernel before     5.0.7. A NULL pointer dereference can occur when     megasas_create_frame_pool() fails in     megasas_alloc_cmds() in     drivers/scsi/megaraid/megaraid_sas_base.c. This causes a     Denial of Service, related to a use-after-free.
    (CVE-2019-11810)

  - An out-of-bounds access issue was found in the Linux     kernel, all versions through 5.3, in the way Linux     kernel's KVM hypervisor implements the Coalesced MMIO     write operation. It operates on an MMIO ring buffer     'struct kvm_coalesced_mmio' object, wherein write     indices 'ring->first' and 'ring->last' value could be     supplied by a host user-space process. An unprivileged     host user or process with access to '/dev/kvm' device     could use this flaw to crash the host kernel, resulting     in a denial of service or potentially escalating     privileges on the system. (CVE-2019-14821)

  - An infinite loop issue was found in the vhost_net kernel     module in Linux Kernel up to and including v5.1-rc6,     while handling incoming packets in handle_rx(). It could     occur if one end sends packets faster than the other end     can process them. A guest user, maybe remote one, could     use this flaw to stall the vhost_net kernel thread,     resulting in a DoS scenario. (CVE-2019-3900)

  - The mincore() implementation in mm/mincore.c in the     Linux kernel through 4.19.13 allowed local attackers to     observe page cache access patterns of other processes on     the same system, potentially allowing sniffing of secret     information. (Fixing this affects the output of the     fincore program.) Limited remote exploitation may be     possible, as demonstrated by latency differences in     accessing public files from an Apache HTTP Server.
    (CVE-2019-5489)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The SUSE Linux Enterprise 12-SP3 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2018-12207: Untrusted virtual machines on Intel CPUs could exploit a race condition in the Instruction Fetch Unit of the Intel CPU to cause a Machine Exception during Page Size Change, causing the CPU core to be non-functional.

The Linux Kernel kvm hypervisor was adjusted to avoid page size changes in executable pages by splitting / merging huge pages into small pages as needed. More information can be found on https://www.suse.com/support/kb/doc/?id=7023735 CVE-2019-16995: Fix a memory leak in hsr_dev_finalize() if hsr_add_port failed to add a port, which may have caused denial of service (bsc#1152685).

CVE-2019-11135: Aborting an asynchronous TSX operation on Intel CPUs with Transactional Memory support could be used to facilitate sidechannel information leaks out of microarchitectural buffers, similar to the previously described 'Microarchitectural Data Sampling' attack.

The Linux kernel was supplemented with the option to disable TSX operation altogether (requiring CPU Microcode updates on older systems) and better flushing of microarchitectural buffers (VERW).

The set of options available is described in our TID at https://www.suse.com/support/kb/doc/?id=7024251 CVE-2019-16233: drivers/scsi/qla2xxx/qla_os.c did not check the alloc_workqueue return value, leading to a NULL pointer dereference. (bsc#1150457).
