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 NFSv2 and NFSv3 server implementations in the Linux     kernel through 4.10.13 lacked certain checks for the     end of a buffer. A remote attacker could trigger a     pointer-arithmetic error or possibly cause other     unspecified impacts using crafted requests related to     fs/nfsd/nfs3xdr.c and     fs/nfsd/nfsxdr.c.(CVE-2017-7895i1/4%0

  - A flaw was found in the Linux kernel's ACPI subsystem     where a function 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 when using a     specially crafted ACPI table.(CVE-2017-13695i1/4%0

  - It was found that fanout_add() in     'net/packet/af_packet.c' in the Linux kernel, before     version 4.13.6, allows local users to gain privileges     via crafted system calls that trigger mishandling of     packet_fanout data structures, because of a race     condition (involving fanout_add and packet_do_bind)     that leads to a use-after-free bug.(CVE-2017-15649i1/4%0

  - Race condition in kernel/ucount.c in the Linux kernel     through 4.10.2 allows local users to cause a denial of     service (use-after-free and system crash) or possibly     have unspecified other impact via crafted system calls     that leverage certain decrement behavior that causes     incorrect interaction between put_ucounts and     get_ucounts.(CVE-2017-6874i1/4%0

  - An out-of-bounds memory access flaw, CVE-2014-7825, was     found in the syscall tracing functionality of the Linux     kernel's perf subsystem. A local, unprivileged user     could use this flaw to crash the system. Additionally,     an out-of-bounds memory access flaw, CVE-2014-7826, was     found in the syscall tracing functionality of the Linux     kernel's ftrace subsystem. On a system with ftrace     syscall tracing enabled, a local, unprivileged user     could use this flaw to crash the system, or escalate     their privileges.(CVE-2014-7825i1/4%0

  - The Salsa20 encryption algorithm in the Linux kernel,     before 4.14.8, does not correctly handle zero-length     inputs. This allows a local attacker the ability to use     the AF_ALG-based skcipher interface to cause a denial     of service (uninitialized-memory free and kernel crash)     or have an 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 are     vulnerable.(CVE-2017-17805i1/4%0

  - The msm_ipc_router_bind_control_port function in     net/ipc_router/ipc_router_core.c in the IPC router     kernel module for the Linux kernel 3.x, as used in     Qualcomm Innovation Center (QuIC) Android contributions     for MSM devices and other products, does not verify     that a port is a client port, which allows attackers to     gain privileges or cause a denial of service (race     condition and list corruption) by making many     BIND_CONTROL_PORT ioctl calls.(CVE-2016-2059i1/4%0

  - The do_remount function in fs/namespace.c in the Linux     kernel through 3.16.1 does not maintain the     MNT_LOCK_READONLY bit across a remount of a bind mount,     which allows local users to bypass an intended     read-only restriction and defeat certain sandbox     protection mechanisms via a 'mount -o remount' command     within a user namespace.(CVE-2014-5206i1/4%0

  - The ati_remote2_probe function in     drivers/input/misc/ati_remote2.c in the Linux kernel     before 4.5.1 allows physically proximate attackers to     cause a denial of service (NULL pointer dereference and     system crash) via a crafted endpoints value in a USB     device descriptor.(CVE-2016-2185i1/4%0

  - It was found that the fix for CVE-2014-3601 was     incomplete: the Linux kernel's kvm_iommu_map_pages()     function still handled IOMMU mapping failures     incorrectly. A privileged user in a guest with an     assigned host device could use this flaw to crash the     host.(CVE-2014-8369i1/4%0

  - A NULL pointer dereference was found in     net/rds/rdma.c:__rds_rdma_map() function in the Linux     kernel allowing local attackers to cause a system panic     and a denial-of-service.(CVE-2018-7492i1/4%0

  - An issue was discovered in the XFS filesystem in     fs/xfs/xfs_icache.c in the Linux kernel. There is a     NULL pointer dereference leading to a system panic in     lookup_slow() on a NULL inode-i1/4zi_ops pointer when     doing pathwalks on a corrupted xfs image. This occurs     because of a lack of proper validation that cached     inodes are free during an allocation.(CVE-2018-13093i1/4%0

  - The iowarrior_probe function in     drivers/usb/misc/iowarrior.c in the Linux kernel before     4.5.1 allows physically proximate attackers to cause a     denial of service (NULL pointer dereference and system     crash) via a crafted endpoints value in a USB device     descriptor.(CVE-2016-2188i1/4%0

  - Linux kernel built with the 802.1Q/802.1ad     VLAN(CONFIG_VLAN_8021Q) OR Virtual eXtensible Local     Area Network(CONFIG_VXLAN) with Transparent Ethernet     Bridging(TEB) GRO support, is vulnerable to a stack     overflow issue. It could occur while receiving large     packets via GRO path, as an unlimited recursion could     unfold in both VLAN and TEB modules, leading to a stack     corruption in the kernel.(CVE-2016-7039i1/4%0

  - The msr_mtrr_valid function in arch/x86/kvm/mtrr.c in     the Linux kernel before 4.6.1 supports MSR 0x2f8, which     allows guest OS users to read or write to the     kvm_arch_vcpu data structure, and consequently obtain     sensitive information or cause a denial of service     (system crash), via a crafted ioctl     call.(CVE-2016-3713i1/4%0

  - A flaw was found in the way the Linux kernel's VFS     subsystem handled reference counting when performing     unmount operations on symbolic links. A local,     unprivileged user could use this flaw to exhaust all     available memory on the system or, potentially, trigger     a use-after-free error, resulting in a system crash or     privilege escalation.(CVE-2014-5045i1/4%0

  - The KEYS subsystem in the Linux kernel before 4.13.10     does not correctly synchronize the actions of updating     versus finding a key in the 'negative' state to avoid a     race condition, which allows local users to cause a     denial of service or possibly have unspecified other     impact via crafted system calls.(CVE-2017-15951i1/4%0

  - The skb_flow_dissect function in     net/core/flow_dissector.c in the Linux kernel through     3.12 allows remote attackers to cause a denial of     service (infinite loop) via a small value in the IHL     field of a packet with IPIP     encapsulation.(CVE-2013-4348i1/4%0

  - The Linux kernel through 3.17.4 does not properly     restrict dropping of supplemental group memberships in     certain namespace scenarios, which allows local users     to bypass intended file permissions by leveraging a     POSIX ACL containing an entry for the group category     that is more restrictive than the entry for the other     category, aka a 'negative groups' issue, related to     kernel/groups.c, kernel/uid16.c, and     kernel/user_namespace.c.(CVE-2014-8989i1/4%0

  - An infinite-loop flaw was found in the kernel. When a     local user calls the sys_writev syscall with a     specially crafted sequence of iov structs, the     fuse_fill_write_pages kernel function might never     terminate, instead continuing in a tight loop. This     process cannot be terminated and requires a     reboot.(CVE-2015-8785i1/4%0
