According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - A memory corruption flaw was found in the way the USB     ConnectTech WhiteHEAT serial driver processed     completion commands sent via USB Request Blocks     buffers. An attacker with physical access to the system     could use this flaw to crash the system or,     potentially, escalate their privileges on the     system.(CVE-2014-3185i1/4%0

  - Use-after-free vulnerability in the msm_set_crop     function in drivers/media/video/msm/msm_camera.c in the     MSM-Camera driver for the Linux kernel 3.x, as used in     Qualcomm Innovation Center (QuIC) Android contributions     for MSM devices and other products, allows attackers to     gain privileges or cause a denial of service (memory     corruption) via an application that makes a crafted     ioctl call.(CVE-2015-0568i1/4%0

  - The vivid_fb_ioctl function in     drivers/media/platform/vivid/vivid-osd.c in the Linux     kernel through 4.3.3 does not initialize a certain     structure member, which allows local users to obtain     sensitive information from kernel memory via a crafted     application.(CVE-2015-7884i1/4%0

  - The usb_get_bos_descriptor function in     drivers/usb/core/config.c in the Linux kernel can allow     a local users to cause a denial of service     (out-of-bounds read and system crash) or possibly have     unspecified other impact via a crafted USB     device.(CVE-2017-16535i1/4%0

  - The ACPI parsing functionality in the Linux kernel does     not flush the node and node_ext caches which causes a     kernel stack dump. This allows local users to obtain     sensitive information from kernel memory and use this     information to bypass the KASLR protection mechanism by     creating and applying crafted ACPI     table.(CVE-2017-13694i1/4%0

  - The is_ashmem_file function in     drivers/staging/android/ashmem.c in a certain Qualcomm     Innovation Center (QuIC) Android patch for the Linux     kernel 3.x mishandles pointer validation within the     KGSL Linux Graphics Module, which allows attackers to     bypass intended access restrictions by using the     /ashmem string as the dentry name.(CVE-2016-5340i1/4%0

  - It was found that the Linux kernel did not properly     account file descriptors passed over the unix socket     against the process limit. A local user could use this     flaw to exhaust all available memory on the     system.(CVE-2013-4312i1/4%0

  - Kernel memory corruption due to a buffer overflow was     found in brcmf_cfg80211_mgmt_tx() function in Linux     kernels from v3.9-rc1 to v4.13-rc1. The vulnerability     can be triggered by sending a crafted NL80211_CMD_FRAME     packet via netlink. This flaw is unlikely to be     triggered remotely as certain userspace code is needed     for this. An unprivileged local user could use this     flaw 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 unlikely.(CVE-2017-7541i1/4%0

  - A flaw in the netback module allowed frontends to     control mapping of requests to request queues. An     attacker can change this mapping by requesting invalid     mapping requests allowing the (usually privileged)     backend to access out-of-bounds memory access for     reading and writing.(CVE-2018-15471i1/4%0

  - A buffer overflow vulnerability due to a lack of input     filtering of incoming fragmented datagrams was found in     the IP-over-1394 driver firewire-net in a fragment     handling code in the Linux kernel. The vulnerability     exists since firewire supported IPv4, i.e. since     version 2.6.31 (year 2009) till version v4.9-rc4. A     maliciously formed fragment with a respectively large     datagram offset would cause a memcpy() past the     datagram buffer, which would cause a system panic or     possible arbitrary code execution.The flaw requires     firewire-net module to be loaded and is remotely     exploitable from connected firewire devices, but not     over a local network.(CVE-2016-8633i1/4%0

  - It was found that the Linux kernel can hit a BUG_ON()     statement in the __xfs_get_blocks() in the     fs/xfs/xfs_aops.c because of a race condition between     direct and memory-mapped I/O associated with a hole in     a file that is handled with BUG_ON() instead of an I/O     failure. This allows a local unprivileged attacker to     cause a system crash and a denial of     service.(CVE-2016-10741i1/4%0

  - A vulnerability was found in the Linux kernel. The     pointer to the netlink socket attribute is not checked,     which could cause a null pointer dereference when     parsing the nested attributes in function     tipc_nl_publ_dump(). This allows local users to cause a     DoS.(CVE-2016-4951i1/4%0

  - It was reported that with Linux kernel, earlier than     version v4.10-rc8, an application may trigger a BUG_ON     in sctp_wait_for_sndbuf if the socket tx buffer is     full, a thread is waiting on it to queue more data, and     meanwhile another thread peels off the association     being used by the first thread.(CVE-2017-5986i1/4%0

  - The kvm_vm_ioctl_check_extension function in     arch/powerpc/kvm/powerpc.c in the Linux kernel before     4.13.11 allows local users to cause a denial of service     (NULL pointer dereference and system crash) via a     KVM_CHECK_EXTENSION KVM_CAP_PPC_HTM ioctl call to     /dev/kvm.(CVE-2017-15306i1/4%0

  - A flaw was found in the way the Linux kernel's 32-bit     emulation implementation handled forking or closing of     a task with an 'int80' entry. A local user could     potentially use this flaw to escalate their privileges     on the system.(CVE-2015-2830i1/4%0

  - A flaw was found in the way the Linux kernel's SCTP     implementation validated INIT chunks when performing     Address Configuration Change (ASCONF). A remote     attacker could use this flaw to crash the system by     sending a specially crafted SCTP packet to trigger a     NULL pointer dereference on the     system.(CVE-2014-7841i1/4%0

  - A race condition issue leading to a use-after-free flaw     was found in the way the raw packet sockets are     implemented in the Linux kernel networking subsystem     handling synchronization. A local user able to open a     raw packet socket (requires the CAP_NET_RAW capability)     can use this issue to crash the     system.(CVE-2017-1000111)

  - A flaw was found in the way the Linux kernel performed     forking inside of a transaction. A local, unprivileged     user on a PowerPC system that supports transactional     memory could use this flaw to crash the     system.(CVE-2014-2673i1/4%0

  - The hashbin_delete function in net/irda/irqueue.c in     the Linux kernel improperly manages lock dropping,     which allows local users to cause a denial of service     (deadlock) via crafted operations on IrDA     devices.(CVE-2017-6348i1/4%0

  - An out-of-bounds flaw was found in the kernel, where     the length of the sockaddr parameter was not checked in     the pptp_bind() and pptp_connect() functions. As a     result, more kernel memory was copied out than     required, leaking information from the kernel stack     (including kernel addresses). A local system user could     exploit this flaw to bypass kernel ASLR or leak other     information.(CVE-2015-8569i1/4%0

Security fix for CVE-2017-13693, CVE-2017-13694, CVE-2017-13695.

This provides fixes for the user space ACPICA tools only. Any kernel updates are handled separately.

This update also includes the upgrade to the 20190209 version of the upstream source. 

---------------------------------------- 09 February 2018. Summary of changes for version 20180209 :

1) ACPICA kernel-resident subsystem :

Completed the final integration of the recent changes to Package Object handling and the module-level AML code support. This allows forward references from individual package elements when the package object is declared from within module-level code blocks. Provides compatibility with other ACPI implementations.

The new architecture for the AML module-level code has been completed and is now the default for the ACPICA code. This new architecture executes the module-level code in-line as the ACPI table is loaded/parsed instead of the previous architecture which deferred this code until after the table was fully loaded. This solves some ASL code ordering issues and provides compatibility with other ACPI implementations. At this time, there is an option to fallback to the earlier architecture, but this support is deprecated and is planned to be completely removed later this year.

Added a compile-time option to ignore AE_NOT_FOUND exceptions during resolution of named reference elements within Package objects.
Although this is potentially a serious problem, it can generate a lot of noise/errors on platforms whose firmware carries around a bunch of unused Package objects. To disable these errors, define ACPI_IGNORE_PACKAGE_RESOLUTION_ERRORS in the OS-specific header. All errors are always reported for ACPICA applications such as AcpiExec.

Fixed a regression related to the explicit type-conversion AML operators (ToXXXX). The regression was introduced early in 2017 but was not seen until recently because these operators are not fully supported by other ACPI implementations and are thus rarely used by firmware developers. The operators are defined by the ACPI specification to not implement the 'implicit result object conversion'. The regression incorrectly introduced this object conversion for the following explicit conversion operators :

  - ToInteger

  - ToString

  - ToBuffer

  - ToDecimalString

  - ToHexString

  - ToBCD

  - FromBCD

2) iASL Compiler/Disassembler and Tools :

iASL: Fixed a problem with the compiler constant folding feature as related to the ToXXXX explicit conversion operators. These operators do not support the 'implicit result object conversion' by definition.
Thus, ASL expressions that use these operators cannot be folded to a simple Store operator because Store implements the implicit conversion. This change uses the CopyObject operator for the ToXXXX operator folding instead. CopyObject is defined to not implement implicit result conversions and is thus appropriate for folding the ToXXXX operators.

iASL: Changed the severity of an error condition to a simple warning for the case where a symbol is declared both locally and as an external symbol. This accommodates existing ASL code.

AcpiExec: The -ep option to enable the new architecture for module-level code has been removed. It is replaced by the -dp option which instead has the opposite effect: it disables the new architecture (the default) and enables the legacy architecture. When the legacy code is removed in the future, the -dp option will be removed also.

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - The iscsi_if_rx function in     drivers/scsi/scsi_transport_iscsi.c in the Linux kernel     through 4.13.2 allows local users to cause a denial of     service (panic) by leveraging incorrect length     validation.(CVE-2017-14489)

  - The move_pages system call in mm/migrate.c in the Linux     kernel before 4.12.9 doesn't check the effective uid of     the target process, enabling a local attacker to learn     the memory layout of a setuid executable despite     ASLR.(CVE-2017-14140)

  - The offset2lib patch as used in the Linux Kernel     contains a vulnerability that allows a PIE binary to be     execve()'ed with 1GB of arguments or environmental     strings then the stack occupies the address 0x80000000     and the PIE binary is mapped above 0x40000000     nullifying the protection of the offset2lib patch. This     affects Linux Kernel version 4.11.5 and earlier. This     is a different issue than CVE-2017-1000371. This issue     appears to be limited to i386 based     systems.(CVE-2017-1000370)

  - Race condition in fs/timerfd.c in the Linux kernel     before 4.10.15 allows local users to gain privileges or     cause a denial of service (list corruption or     use-after-free) via simultaneous file-descriptor     operations that leverage improper might_cancel     queueing.(CVE-2017-10661)

  - The acpi_ns_evaluate() function in     drivers/acpi/acpica/nseval.c in the Linux kernel     through 4.12.9 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-2017-13695)

  - The acpi_ds_create_operands() function in     drivers/acpi/acpica/dsutils.c in the Linux kernel     through 4.12.9 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-2017-13693)

  - The tcp_disconnect function in net/ipv4/tcp.c in the     Linux kernel before 4.12 allows local users to cause a     denial of service (__tcp_select_window divide-by-zero     error and system crash) by triggering a disconnect     within a certain tcp_recvmsg code path.(CVE-2017-14106)

  - The native Bluetooth stack in the Linux Kernel (BlueZ),     starting at the Linux kernel version 3.3-rc1 and up to     and including 4.13.1, are vulnerable to a stack     overflow vulnerability in the processing of L2CAP     configuration responses resulting in Remote code     execution in kernel space.(CVE-2017-1000251

  - )

  - The prepare_vmcs02 function in arch/x86/kvm/vmx.c in     the Linux kernel through 4.13.3 does not ensure that     the 'CR8-load exiting' and 'CR8-store exiting' L0     vmcs02 controls exist in cases where L1 omits the 'use     TPR shadow' vmcs12 control, which allows KVM L2 guest     OS users to obtain read and write access to the     hardware CR8 register.(CVE-2017-12154)
