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 :

  - In the Linux kernel through 4.19, a use-after-free can     occur due to a race condition between fanout_add from     setsockopt and bind on an AF_PACKET socket. This issue     exists because of the     15fe076edea787807a7cdc168df832544b58eba6 incomplete fix     for a race condition. The code mishandles a certain     multithreaded case involving a packet_do_bind     unregister action followed by a packet_notifier     register action. Later, packet_release operates on only     one of the two applicable linked lists. The attacker     can achieve Program Counter control.(CVE-2018-18559i1/4%0

  - 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. A local users could obtain     sensitive information from kernel memory and bypass the     KASLR protection mechanism (in the kernel through 4.9)     via a crafted ACPI table.(CVE-2017-11472i1/4%0

  - Race condition in net/packet/af_packet.c in the Linux     kernel allows local users to cause a denial of service     (use-after-free) or possibly have unspecified other     impact via a multithreaded application that makes     PACKET_FANOUT setsockopt system calls.(CVE-2017-6346i1/4%0

  - Multiple race conditions in ipc/shm.c in the Linux     kernel before 3.12.2 allow local users to cause a     denial of service (use-after-free and system crash) or     possibly have unspecified other impact via a crafted     application that uses shmctl IPC_RMID operations in     conjunction with other shm system     calls.(CVE-2013-7026i1/4%0

  - An issue was discovered in the Linux kernel. A NULL     pointer dereference and panic in hfsplus_lookup() in     the fs/hfsplus/dir.c function can occur when opening a     file (that is purportedly a hard link) in an hfs+     filesystem that has malformed catalog data, and is     mounted read-only without a metadata     directory.(CVE-2018-14617i1/4%0

  - The treo_attach function in drivers/usb/serial/visor.c     in the Linux kernel before 4.5 allows physically     proximate attackers to cause a denial of service (NULL     pointer dereference and system crash) or possibly have     unspecified other impact by inserting a USB device that     lacks a (1) bulk-in or (2) interrupt-in     endpoint.(CVE-2016-2782i1/4%0

  - An information-exposure flaw was found in the Linux     kernel where the pcpu_embed_first_chunk() function in     mm/percpu.c allows local users to obtain kernel-object     address information by reading the kernel log (dmesg).
    However, this address is not static and cannot be used     to commit a further attack.(CVE-2018-5995i1/4%0

  - Buffer overflow in net/ceph/auth_x.c in Ceph, as used     in the Linux kernel before 3.16.3, allows remote     attackers to cause a denial of service (memory     corruption and panic) or possibly have unspecified     other impact via a long unencrypted auth     ticket.(CVE-2014-6416i1/4%0

  - It was found that the Linux kernel's ptrace subsystem     allowed a traced process' instruction pointer to be set     to a non-canonical memory address without forcing the     non-sysret code path when returning to user space. A     local, unprivileged user could use this flaw to crash     the system or, potentially, escalate their privileges     on the system.Note: The CVE-2014-4699 issue only     affected systems using an Intel CPU.(CVE-2014-4699i1/4%0

  - The snd_compr_tstamp function in     sound/core/compress_offload.c in the Linux kernel     through 4.7, as used in Android before 2016-08-05 on     Nexus 5 and 7 (2013) devices, does not properly     initialize a timestamp data structure, which allows     attackers to obtain sensitive information via a crafted     application, aka Android internal bug 28770164 and     Qualcomm internal bug CR568717.(CVE-2014-9892i1/4%0

  - A flaw was found in the way the Linux kernel's ext4     file system handled the 'page size i1/4z block size'     condition when the fallocate zero range functionality     was used. A local attacker could use this flaw to crash     the system.(CVE-2015-0275i1/4%0

  - An information leak flaw was found in the way the Linux     kernel's ISO9660 file system implementation accessed     data on an ISO9660 image with RockRidge Extension     Reference (ER) records. An attacker with physical     access to the system could use this flaw to disclose up     to 255 bytes of kernel memory.(CVE-2014-9584i1/4%0

  - The pivot_root implementation in fs/namespace.c in the     Linux kernel through 3.17 does not properly interact     with certain locations of a chroot directory, which     allows local users to cause a denial of service     (mount-tree loop) via . (dot) values in both arguments     to the pivot_root system call.(CVE-2014-7970i1/4%0

  - arch/x86/kvm/emulate.c in the Linux kernel before     4.8.12 does not properly initialize Code Segment (CS)     in certain error cases, which allows local users to     obtain sensitive information from kernel stack memory     via a crafted application.(CVE-2016-9756i1/4%0

  - A flaw was found in the Linux kernel where the     swiotlb_print_info() function in lib/swiotlb.c allows     local users to obtain some kernel address information     by reading the kernel log (dmesg). This address is not     useful to commit a further attack.(CVE-2018-5953i1/4%0

  - A flaw was found in the way the Linux kernel's file     system implementation handled rename operations in     which the source was inside and the destination was     outside of a bind mount. A privileged user inside a     container could use this flaw to escape the bind mount     and, potentially, escalate their privileges on the     system.(CVE-2015-2925i1/4%0

  - A use-after-free fault in the Linux kernel's usbtv     driver could allow an attacker to cause a denial of     service (system crash), or have unspecified other     impacts, by triggering failure of audio registration of     USB hardware using the usbtv kernel     module.(CVE-2017-17975i1/4%0

  - 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-2017-7889i1/4%0

  - A flaw was discovered in the way the kernel allows     stackable filesystems to overlay. A local attacker who     is able to mount filesystems can abuse this flaw to     escalate privileges.(CVE-2014-9922i1/4%0

  - sound/core/timer.c in the Linux kernel before 4.4.1     retains certain linked lists after a close or stop     action, which allows local users to cause a denial of     service (system crash) via a crafted ioctl call,     related to the (1) snd_timer_close and (2)
    _snd_timer_stop functions.(CVE-2016-2548i1/4%0

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

  - A flaw was found in the way the Linux kernel's Crypto     subsystem handled automatic loading of kernel modules.
    A local user could use this flaw to load any installed     kernel module, and thus increase the attack surface of     the running kernel.(CVE-2014-9644)

  - The Btrfs implementation in the Linux kernel before     3.19 does not ensure that the visible xattr state is     consistent with a requested replacement, which allows     local users to bypass intended ACL settings and gain     privileges via standard filesystem operations (1)     during an xattr-replacement time window, related to a     race condition, or (2) after an xattr-replacement     attempt that fails because the data does not     fit.(CVE-2014-9710)

  - An integer overflow flaw was found in the way the Linux     kernel's netfilter connection tracking implementation     loaded extensions. An attacker on a local network could     potentially send a sequence of specially crafted     packets that would initiate the loading of a large     number of extensions, causing the targeted system in     that network to crash.(CVE-2014-9715)

  - A symlink size validation was missing in Linux kernels     built with UDF file system (CONFIG_UDF_FS) support,     allowing the corruption of kernel memory. An attacker     able to mount a corrupted/malicious UDF file system     image could cause the kernel to crash.(CVE-2014-9728)

  - A symlink size validation was missing in Linux kernels     built with UDF file system (CONFIG_UDF_FS) support,     allowing the corruption of kernel memory. An attacker     able to mount a corrupted/malicious UDF file system     image could cause the kernel to crash.(CVE-2014-9729)

  - It was found that the Linux kernel KVM subsystem's     sysenter instruction emulation was not sufficient. An     unprivileged guest user could use this flaw to escalate     their privileges by tricking the hypervisor to emulate     a SYSENTER instruction in 16-bit mode, if the guest OS     did not initialize the SYSENTER model-specific     registers (MSRs). Note: Certified guest operating     systems for Red Hat Enterprise Linux with KVM do     initialize the SYSENTER MSRs and are thus not     vulnerable to this issue when running on a KVM     hypervisor.(CVE-2015-0239)

  - A flaw was found in the way the Linux kernel's XFS file     system handled replacing of remote attributes under     certain conditions. A local user with access to XFS     file system mount could potentially use this flaw to     escalate their privileges on the system.(CVE-2015-0274)

  - A flaw was found in the way the Linux kernel's ext4     file system handled the 'page size i1/4z block size'     condition when the fallocate zero range functionality     was used. A local attacker could use this flaw to crash     the system.(CVE-2015-0275)

  - Race condition in the handle_to_path function in     fs/fhandle.c in the Linux kernel through 3.19.1 allows     local users to bypass intended size restrictions and     trigger read operations on additional memory locations     by changing the handle_bytes value of a file handle     during the execution of this function.(CVE-2015-1420)

  - A use-after-free flaw was found in the way the Linux     kernel's SCTP implementation handled authentication key     reference counting during INIT collisions. A remote     attacker could use this flaw to crash the system or,     potentially, escalate their privileges on the     system.(CVE-2015-1421)

  - The IPv4 implementation in the Linux kernel before     3.18.8 does not properly consider the length of the     Read-Copy Update (RCU) grace period for redirecting     lookups in the absence of caching, which allows remote     attackers to cause a denial of service (memory     consumption or system crash) via a flood of     packets.(CVE-2015-1465)

  - A flaw was found in the way the nft_flush_table()     function of the Linux kernel's netfilter tables     implementation flushed rules that were referencing     deleted chains. A local user who has the CAP_NET_ADMIN     capability could use this flaw to crash the     system.(CVE-2015-1573)

  - An integer overflow flaw was found in the way the Linux     kernel randomized the stack for processes on certain     64-bit architecture systems, such as x86-64, causing     the stack entropy to be reduced by four.(CVE-2015-1593)
