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 IPv6 SCTP implementation in net/sctp/ipv6.c in the     Linux kernel through 3.11.1 uses data structures and     function calls that do not trigger an intended     configuration of IPsec encryption, which allows remote     attackers to obtain sensitive information by sniffing     the network.(CVE-2013-4350i1/4%0

  - The sg_ioctl function in drivers/scsi/sg.c in the Linux     kernel allows local users to cause a denial of service     (stack-based buffer overflow) or possibly have     unspecified other impacts via a large command size in     an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds     write access in the sg_write function.(CVE-2017-7187i1/4%0

  - An issue was discovered in can_can_gw_rcv in     net/can/gw.c in the Linux kernel through 4.19.13. The     CAN frame modification rules allow bitwise logical     operations that can be also applied to the can_dlc     field. Because of a missing check, the CAN drivers may     write arbitrary content beyond the data registers in     the CAN controller's I/O memory when processing can-gw     manipulated outgoing frames. This is related to     cgw_csum_xor_rel. An unprivileged user can trigger a     system crash (general protection     fault).(CVE-2019-3701i1/4%0

  - net/rds/sysctl.c in the Linux kernel before 3.19 uses     an incorrect data type in a sysctl table, which allows     local users to obtain potentially sensitive information     from kernel memory or possibly have unspecified other     impact by accessing a sysctl entry.(CVE-2015-2042i1/4%0

  - The inet_csk_clone_lock function in     net/ipv4/inet_connection_sock.c in the Linux kernel     allows attackers to cause a denial of service (double     free) or possibly have unspecified other impact by     leveraging use of the accept system call. 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 we     believe it is unlikely.(CVE-2017-8890i1/4%0

  - The overlayfs implementation in the linux (aka Linux     kernel) package before 3.19.0-21.21 in Ubuntu through     15.04 does not properly check permissions for file     creation in the upper filesystem directory, which     allows local users to obtain root access by leveraging     a configuration in which overlayfs is permitted in an     arbitrary mount namespace.(CVE-2015-1328i1/4%0

  - The xfs_dinode_verify function in     fs/xfs/libxfs/xfs_inode_buf.c in the Linux kernel     through 4.16.3 allows local users to cause a denial of     service (xfs_ilock_attr_map_shared invalid pointer     dereference) via a crafted xfs image.(CVE-2018-10322i1/4%0

  - In the flush_tmregs_to_thread function in     arch/powerpc/kernel/ptrace.c in the Linux kernel before     4.13.5, a guest kernel crash can be triggered from     unprivileged userspace during a core dump on a POWER     host due to a missing processor feature check and an     erroneous use of transactional memory (TM) instructions     in the core dump path, leading to a denial of     service.(CVE-2018-1091i1/4%0

  - ** DISPUTED ** drivers/scsi/libsas/sas_scsi_host.c in     the Linux kernel before 4.16 allows local users to     cause a denial of service (ata qc leak) by triggering     certain failure conditions. NOTE: a third party     disputes the relevance of this report because the     failure can only occur for physically proximate     attackers who unplug SAS Host Bus Adapter     cables.(CVE-2018-10021i1/4%0

  - A use-after-free flaw was discovered in the Linux     kernel's tty subsystem, which allows for the disclosure     of uncontrolled memory location and possible kernel     panic. The information leak is caused by a race     condition when attempting to set and read the tty line     discipline. A local attacker could use the TIOCSETD     (via tty_set_ldisc ) to switch to a new line discipline     a concurrent call to a TIOCGETD ioctl performing a read     on a given tty could then access previously allocated     memory. Up to 4 bytes could be leaked when querying the     line discipline or the kernel could panic with a     NULL-pointer dereference.(CVE-2016-0723i1/4%0

  - An out-of-bounds read flaw was found in the way the     Logitech Unifying receiver driver handled HID reports     with an invalid device_index value. 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-2014-3182i1/4%0

  - arch/x86/kvm/emulate.c in the Linux kernel through     4.9.3 allows local users to obtain sensitive     information from kernel memory or cause a denial of     service (use-after-free) via a crafted application that     leverages instruction emulation for fxrstor, fxsave,     sgdt, and sidt.(CVE-2017-2584i1/4%0

  - A flaw was found in the way the Linux kernel handled     IRET faults during the processing of NMIs. An     unprivileged, local user could use this flaw to crash     the system or, potentially (although highly unlikely),     escalate their privileges on the     system.(CVE-2015-5157i1/4%0

  - drivers/media/media-device.c in the Linux kernel before     3.11, as used in Android before 2016-08-05 on Nexus 5     and 7 (2013) devices, does not properly initialize     certain data structures, which allows local users to     obtain sensitive information via a crafted application,     aka Android internal bug 28750150 and Qualcomm internal     bug CR570757, a different vulnerability than     CVE-2014-1739.(CVE-2014-9895i1/4%0

  - A use-after-free vulnerability in sys_ioprio_get() was     found due to get_task_ioprio() accessing the     task-i1/4zio_context without holding the task lock and     could potentially race with exit_io_context(), leading     to a use-after-free.(CVE-2016-7911i1/4%0

  - A flaw was found in the Linux kernel which is related     to the user namespace lazily unmounting file systems.
    The fs_pin struct has two members (m_list and s_list)     which are usually initialized on use in the     pin_insert_group function. However, these members might     go unmodified in this case, the system panics when it     attempts to destroy or free them. This flaw could be     used to launch a denial-of-service     attack.(CVE-2015-4178i1/4%0

  - A flaw was found in the Linux kernel's implementation     of raw_sendmsg allowing a local attacker to panic the     kernel or possibly leak kernel addresses. A local     attacker, with the privilege of creating raw sockets,     can abuse a possible race condition when setting the     socket option to allow the kernel to automatically     create ip header values and thus potentially escalate     their privileges.(CVE-2017-17712i1/4%0

  - A flaw was discovered in the F2FS filesystem code in     fs/f2fs/super.c in the Linux kernel. A denial of     service, due to an out-of-bounds memory access, can     occur upon encountering an abnormal bitmap size when     mounting a crafted f2fs image.(CVE-2018-13096i1/4%0

  - A NULL pointer dereference flaw was found in the way     the Linux kernel's madvise MADV_WILLNEED functionality     handled page table locking. A local, unprivileged user     could use this flaw to crash the     system.(CVE-2014-8173i1/4%0

  - An out-of-bounds heap memory access leading to a Denial     of Service, heap disclosure, or further impact was     found in setsockopt(). The function call is normally     restricted to root, however some processes with     cap_sys_admin may also be able to trigger this flaw in     privileged container environments.(CVE-2016-4998i1/4%0

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

  - Missing check in fs/inode.c:inode_init_owner() does not     clear SGID bit on non-directories for     non-members.(CVE-2018-13405)

  - A null pointer dereference in dccp_write_xmit()     function in net/dccp/output.c in the Linux kernel     allows a local user to cause a denial of service by a     number of certain crafted system calls.(CVE-2018-1130)

  - A flaw was found in the Linux kernel, before 4.16.6     where the cdrom_ioctl_media_changed function in     drivers/cdrom/cdrom.c allows local attackers to use a     incorrect bounds check in the CDROM driver     CDROM_MEDIA_CHANGED ioctl to read out kernel     memory.(CVE-2018-10940)

  - The madvise_willneed function in the Linux kernel     allows local users to cause a denial of service     (infinite loop) by triggering use of MADVISE_WILLNEED     for a DAX mapping.(CVE-2017-18208)

  - fuse-backed file mmap-ed onto process cmdline arguments     causes denial of service.(CVE-2018-1120)

  - Memory leak in the sas_smp_get_phy_events function in     drivers/scsi/libsas/sas_expander.c in the Linux kernel     allows local users to cause a denial of service (kernel     memory exhaustion) via multiple read accesses to files     in the /sys/class/sas_phy directory.(CVE-2018-7757)

  - A vulnerability was found in the Linux kernel's     kernel/events/core.c:perf_cpu_time_max_percent_handler(     ) function. Local privileged users could exploit this     flaw to cause a denial of service due to integer     overflow or possibly have unspecified other     impact.(CVE-2017-18255)

  - A flaw was found in the Linux kernel in the way a local     user could create keyrings for other users via keyctl     commands. This may allow an attacker to set unwanted     defaults, a denial of service, or possibly leak keyring     information between users.(CVE-2017-18270)

  - The mm subsystem in the Linux kernel through 4.10.10     does not properly enforce the CONFIG_STRICT_DEVMEM     protection mechanism, which allows local users to read     or write to kernel memory locations in the first     megabyte (and bypass slab-allocation access     restrictions) via an application that opens the     /dev/mem file, related to arch/x86/mm/init.c and     drivers/char/mem.c.(CVE-2017-7889)

  - The code in the drivers/scsi/libsas/sas_scsi_host.c     file in the Linux kernel allow a physically proximate     attacker to cause a memory leak in the ATA command     queue and, thus, denial of service by triggering     certain failure conditions.(CVE-2018-10021)

  - A flaw was found in the Linux kernel's client-side     implementation of the cifs protocol. This flaw allows     an attacker controlling the server to kernel panic a     client which has the CIFS server     mounted.(CVE-2018-1066)

  - A flaw was found in the alarm_timer_nsleep() function     in kernel/time/alarmtimer.c in the Linux kernel. The     ktime_add_safe() function is not used and an integer     overflow can happen causing an alarm not to fire or     possibly a denial-of-service if using a large relative     timeout.(CVE-2018-13053)

  - An issue was discovered in the XFS filesystem in     fs/xfs/libxfs/xfs_attr_leaf.c in the Linux kernel. A     NULL pointer dereference may occur for a corrupted xfs     image after xfs_da_shrink_inode() is called with a NULL     bp. This can lead to a system crash and a denial of     service.(CVE-2018-13094)

  - A flaw was found in the Linux Kernel in the     ucma_leave_multicast() function in     drivers/infiniband/core/ucma.c which allows access to a     certain data structure after freeing it in     ucma_process_join(). This allows an attacker to cause a     use-after-free bug and to induce kernel memory     corruption, leading to a system crash or other     unspecified impact. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2018-14734)

  - A race condition in the store_int_with_restart()     function in arch/x86/kernel/cpu/mcheck/mce.c in the     Linux kernel allows local users to cause a denial of     service (panic) by leveraging root access to write to     the check_interval file in a     /sys/devices/system/machinecheck/machinecheck (cpu     number) directory.(CVE-2018-7995)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - drivers/scsi/libsas/sas_scsi_host.c in the Linux kernel before 4.16 allows local users to cause a denial     of service (ata qc leak) by triggering certain failure conditions. NOTE: a third party disputes the     relevance of this report because the failure can only occur for physically proximate attackers who unplug     SAS Host Bus Adapter cables (CVE-2018-10021)

Note that Nessus relies on the presence of the package as reported by the vendor.

The 4.15.17 update contains a number of important fixes across the tree.

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

  - ALSA sequencer core initializes the event pool on     demand by invoking snd_seq_pool_init() when the first     write happens and the pool is empty. A user can reset     the pool size manually via ioctl concurrently, and this     may lead to UAF or out-of-bound access.(CVE-2018-7566)

  - The do_get_mempolicy() function in mm/mempolicy.c in     the Linux kernel allows local users to hit a     use-after-free bug via crafted system calls and thus     cause a denial of service (DoS) or possibly have     unspecified other impact. Due to the nature of the     flaw, privilege escalation cannot be fully ruled     out.(CVE-2018-10675)

  - The Linux kernel has an undefined behavior when an     argument of INT_MIN is passed to the     kernel/signal.c:kill_something_info() function. A local     attacker may be able to exploit this to cause a denial     of service.(CVE-2018-10124)

  - A an integer overflow vulnerability was discovered in     the Linux kernel, from version 3.4 through 4.15, in the     drivers/gpu/drm/udl/udl_fb.c:udl_fb_mmap() function. An     attacker with access to the udldrmfb driver could     exploit this to obtain full read and write permissions     on kernel physical pages, resulting in a code execution     in kernel space.(CVE-2018-8781)

  - The code in the drivers/scsi/libsas/sas_scsi_host.c     file in the Linux kernel allow a physically proximate     attacker to cause a memory leak in the ATA command     queue and, thus, denial of service by triggering     certain failure conditions.(CVE-2018-10021)

  - A flaw was found in the Linux kernel's implementation     of 32-bit syscall interface for bridging. This allowed     a privileged user to arbitrarily write to a limited     range of kernel memory.(CVE-2018-1068)

  - A vulnerability was found in the Linux kernel's     kernel/events/core.c:perf_cpu_time_max_percent_handler(     ) function. Local privileged users could exploit this     flaw to cause a denial of service due to integer     overflow or possibly have unspecified other     impact.(CVE-2017-18255)

  - The kernel_wait4 function in kernel/exit.c in the Linux     kernel, when an unspecified architecture and compiler     is used, might allow local users to cause a denial of     service by triggering an attempted use of the -INT_MIN     value.(CVE-2018-10087)

  - A null pointer dereference in dccp_write_xmit()     function in net/dccp/output.c in the Linux kernel     allows a local user to cause a denial of service by a     number of certain crafted system calls.(CVE-2018-1130)

  - An address corruption flaw was discovered in the Linux     kernel built with hardware breakpoint     (CONFIG_HAVE_HW_BREAKPOINT) support. While modifying a     h/w breakpoint via 'modify_user_hw_breakpoint' routine,     an unprivileged user/process could use this flaw to     crash the system kernel resulting in DoS OR to     potentially escalate privileges on a the     system.(CVE-2018-1000199)
