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 :

  - The kernel package contains the Linux kernel (vmlinuz),     the core of any Linux operating system. The kernel     handles the basic functions of the operating system:
    memory allocation, process allocation, device input and     output, etc.Security Fix(es):A buffer overflow was     discovered in tpacket_rcv() function in the Linux     kernel since v4.6-rc1 through v4.13. A number of     socket-related syscalls can be made to set up a     configuration when each packet received by a network     interface can cause writing up to 10 bytes to a kernel     memory outside of a kernel buffer. This can cause     unspecified kernel data corruption effects, including     damage of in-memory and on-disk XFS     data.(CVE-2017-14497)The qmi_wwan_bind function in     driverset/usb/qmi_wwan.c in the Linux kernel through     4.13.11 allows local users to cause a denial of service     (divide-by-zero error and system crash) or possibly     have unspecified other impact via a crafted USB     device.(CVE-2017-16650)A race condition flaw was found     in the way the Linux kernel's SCTP implementation     handled sctp_accept() during the processing of     heartbeat timeout events. A remote attacker could use     this flaw to prevent further connections to be accepted     by the SCTP server running on the system, resulting in     a denial of service.(CVE-2015-8767)A race condition     flaw was found in the way the Linux kernel's KVM     subsystem handled PIT (Programmable Interval Timer)     emulation. A guest user who has access to the PIT I/O     ports could use this flaw to crash the     host.(CVE-2014-3611)The Linux kernel is vulnerable to a     memory leak in the     driverset/wireless/mac80211_hwsim.c:hwsim_new_radio_nl(     ) function. An attacker could exploit this to cause a     potential denial of service.(CVE-2018-8087)An integer     underflow flaw was found in the way the Linux kernel's     Stream Control Transmission Protocol (SCTP)     implementation processed certain COOKIE_ECHO packets.
    By sending a specially crafted SCTP packet, a remote     attacker could use this flaw to prevent legitimate     connections to a particular SCTP server socket to be     made.(CVE-2014-4667)The cx231xx_usb_probe function in     drivers/media/usb/cx231xx/cx231xx-cards.c in the Linux     kernel through 4.13.11 allows local users to cause a     denial of service (NULL pointer dereference and system     crash) or possibly have unspecified other impact via a     crafted USB device.(CVE-2017-16536)The     snd_usb_create_streams function in sound/usb/card.c in     the Linux kernel, before 4.13.6, allows 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-2017-16529)A flaw was     found in the Linux kernel's random number generator     API. A null pointer dereference in the rngapi_reset     function may result in denial of service, crashing the     system.(CVE-2017-15116)The __netlink_deliver_tap_skb     function in netetlink/af_netlink.c in the Linux kernel,     through 4.14.4, does not restrict observations of     Netlink messages to a single net namespace, when     CONFIG_NLMON is enabled. This 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)arch/arm64/kernel/perf_event.c     in the Linux kernel before 4.1 on arm64 platforms     allows local users to gain privileges or cause a denial     of service (invalid pointer dereference) via vectors     involving events that are mishandled during a span of     multiple HW PMUs.(CVE-2015-8955)The aac_compat_ioctl     function in drivers/scsi/aacraid/linit.c in the Linux     kernel before 3.11.8 does not require the CAP_SYS_RAWIO     capability, which allows local users to bypass intended     access restrictions via a crafted ioctl     call.(CVE-2013-6383)Linux kernel before version     4.16-rc7 is vulnerable to a null pointer dereference in     dccp_write_xmit() function in net/dccp/output.c in that     allows a local user to cause a denial of service by a     number of certain crafted system     calls.(CVE-2018-1130)The Linux kernel is vulerable to a     use-after-free flaw when Transformation User     configuration interface(CONFIG_XFRM_USER) compile-time     configuration were enabled. This vulnerability occurs     while closing a xfrm netlink socket in     xfrm_dump_policy_done. A user/process could abuse this     flaw to potentially escalate their privileges on a     system.(CVE-2017-16939)A vulnerability was found in the     Linux kernel in function rds_inc_info_copy of file     net/rds/recv.c. The last field 'flags' of object     'minfo' is not initialized. This can leak data     previously at the flags location to     userspace.(CVE-2016-5244)A flaw was found in the     kernel's ACPI interpreter when it does not flush the     operand cache and causes a kernel stack dump. This     allows local users to obtain sensitive information from     kernel memory and bypass the KASLR protection     mechanism.(CVE-2017-13693)It was found that     kernel/events/core.c in the Linux kernel mishandles     counter grouping, which allows local users to gain     privileges via a crafted application, related to the     perf_pmu_register and perf_event_open     functions.(CVE-2015-9004)The xfs_bmap_extents_to_btree     function in fs/xfs/libxfs/xfs_bmap.c in the Linux     kernel through 4.16.3 allows local users to cause a     denial of service (xfs_bmapi_write NULL pointer     dereference) via a crafted xfs     image.(CVE-2018-10323)The lrw_crypt() function in     'crypto/lrw.c' in the Linux kernel before 4.5 allows     local users to cause a system crash and a denial of     service by the NULL pointer dereference via accept(2)     system call for AF_ALG socket without calling setkey()     first to set a cipher key.(CVE-2015-8970)The IPv6     fragmentation implementation in the Linux kernel does     not consider that the nexthdr field may be associated     with an invalid option, which allows local users to     cause a denial of service (out-of-bounds read and BUG)     or possibly have unspecified other impact via crafted     socket and send system calls. Due to the nature of the     flaw, privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2017-9074)

Several vulnerabilities have been discovered in the Linux kernel that may lead to privilege escalation, denial of service or information leaks.

  - CVE-2017-7518     Andy Lutomirski discovered that KVM is prone to an     incorrect debug exception (#DB) error occurring while     emulating a syscall instruction. A process inside a     guest can take advantage of this flaw for privilege     escalation inside a guest.

  - CVE-2017-7558 (stretch only)     Stefano Brivio of Red Hat discovered that the SCTP     subsystem is prone to a data leak vulnerability due to     an out-of-bounds read flaw, allowing to leak up to 100     uninitialized bytes to userspace.

  - CVE-2017-10661 (jessie only)     Dmitry Vyukov of Google reported that the timerfd     facility does not properly handle certain concurrent     operations on a single file descriptor. This allows a     local attacker to cause a denial of service or     potentially execute arbitrary code.

  - CVE-2017-11600     Bo Zhang reported that the xfrm subsystem does not     properly validate one of the parameters to a netlink     message. Local users with the CAP_NET_ADMIN capability     can use this to cause a denial of service or potentially     to execute arbitrary code.

  - CVE-2017-12134 / #866511 / XSA-229     Jan H. Schoenherr of Amazon discovered that when Linux     is running in a Xen PV domain on an x86 system, it may     incorrectly merge block I/O requests. A buggy or     malicious guest may trigger this bug in dom0 or a PV     driver domain, causing a denial of service or     potentially execution of arbitrary code.

  This issue can be mitigated by disabling merges on the underlying   back-end block devices, e.g.:echo 2 >   /sys/block/nvme0n1/queue/nomerges

  - CVE-2017-12146 (stretch only)     Adrian Salido of Google reported a race condition in     access to the'driver_override' attribute for platform     devices in sysfs. If unprivileged users are permitted to     access this attribute, this might allow them to gain     privileges.

  - CVE-2017-12153     Bo Zhang reported that the cfg80211 (wifi) subsystem     does not properly validate the parameters to a netlink     message. Local users with the CAP_NET_ADMIN capability     (in any user namespace with a wifi device) can use this     to cause a denial of service.

  - CVE-2017-12154     Jim Mattson of Google reported that the KVM     implementation for Intel x86 processors did not     correctly handle certain nested hypervisor     configurations. A malicious guest (or nested guest in a     suitable L1 hypervisor) could use this for denial of     service.

  - CVE-2017-14106     Andrey Konovalov discovered that a user-triggerable     division by zero in the tcp_disconnect() function could     result in local denial of service.

  - CVE-2017-14140     Otto Ebeling reported that the move_pages() system call     performed insufficient validation of the UIDs of the     calling and target processes, resulting in a partial     ASLR bypass. This made it easier for local users to     exploit vulnerabilities in programs installed with the     set-UID permission bit set.

  - CVE-2017-14156     'sohu0106' reported an information leak in the atyfb     video driver. A local user with access to a framebuffer     device handled by this driver could use this to obtain     sensitive information.

  - CVE-2017-14340     Richard Wareing discovered that the XFS implementation     allows the creation of files with the 'realtime' flag on     a filesystem with no realtime device, which can result     in a crash (oops). A local user with access to an XFS     filesystem that does not have a realtime device can use     this for denial of service.

  - CVE-2017-14489     ChunYu Wang of Red Hat discovered that the iSCSI     subsystem does not properly validate the length of a     netlink message, leading to memory corruption. A local     user with permission to manage iSCSI devices can use     this for denial of service or possibly to execute     arbitrary code.

  - CVE-2017-14497 (stretch only)     Benjamin Poirier of SUSE reported that vnet headers are     not properly handled within the tpacket_rcv() function     in the raw packet (af_packet) feature. A local user with     the CAP_NET_RAW capability can take advantage of this     flaw to cause a denial of service (buffer overflow, and     disk and memory corruption) or have other impact.

  - CVE-2017-1000111     Andrey Konovalov of Google reported a race condition in     the raw packet (af_packet) feature. Local users with the     CAP_NET_RAW capability can use this for denial of     service or possibly to execute arbitrary code.

  - CVE-2017-1000112     Andrey Konovalov of Google reported a race condition     flaw in the UDP Fragmentation Offload (UFO) code. A     local user can use this flaw for denial of service or     possibly to execute arbitrary code.

  - CVE-2017-1000251 / #875881     Armis Labs discovered that the Bluetooth subsystem does     not properly validate L2CAP configuration responses,     leading to a stack-based buffer overflow. This is one of     several vulnerabilities dubbed 'Blueborne'. A nearby     attacker can use this to cause a denial of service or     possibly to execute arbitrary code on a system with     Bluetooth enabled.

  - CVE-2017-1000252 (stretch only)     Jan H. Schoenherr of Amazon reported that the KVM     implementation for Intel x86 processors did not     correctly validate interrupt injection requests. A local     user with permission to use KVM could use this for     denial of service.

  - CVE-2017-1000370     The Qualys Research Labs reported that a large argument     or environment list can result in ASLR bypass for 32-bit     PIE binaries.

  - CVE-2017-1000371     The Qualys Research Labs reported that a large argument     or environment list can result in a stack/heap clash for     32-bit PIE binaries.

  - CVE-2017-1000380     Alexander Potapenko of Google reported a race condition     in the ALSA (sound) timer driver, leading to an     information leak. A local user with permission to access     sound devices could use this to obtain sensitive     information.

Debian disables unprivileged user namespaces by default, but if they are enabled (via the kernel.unprivileged_userns_clone sysctl) then CVE-2017-11600, CVE-2017-14497 and CVE-2017-1000111 can be exploited by any local user.

A buffer overflow was discovered in tpacket_rcv() function in the Linux kernel since v4.6-rc1 through v4.13. A number of socket-related syscalls can be made to set up a configuration when each packet received by a network interface can cause writing up to 10 bytes to a kernel memory outside of a kernel buffer. This can cause unspecified kernel data corruption effects, including damage of in-memory and on-disk XFS data. (CVE-2017-14497)

A kernel data leak due to an out-of-bound read was found in the Linux kernel in inet_diag_msg_sctp{,l}addr_fill() and sctp_get_sctp_info() functions present since version 4.7-rc1 through version 4.13. A data leak happens when these functions fill in sockaddr data structures used to export socket's diagnostic information. As a result, up to 100 bytes of the slab data could be leaked to a userspace.
