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, Hisilicon Network Subsystem (HNS)     does not consider the ETH_SS_PRIV_FLAGS case when     retrieving sset_count data. This allows local users to     cause a denial of service (buffer overflow and memory     corruption) or possibly have unspecified other     impacts.(CVE-2017-18222i1/4%0

  - A flaw was found in the way the Linux kernel's     networking implementation handled UDP packets with     incorrect checksum values. A remote attacker could     potentially use this flaw to trigger an infinite loop     in the kernel, resulting in a denial of service on the     system, or cause a denial of service in applications     using the edge triggered epoll     functionality.(CVE-2015-5366i1/4%0

  - A use-after-free vulnerability was found in the     kernel's socket recvmmsg subsystem. This may allow     remote attackers to corrupt memory and may allow     execution of arbitrary code. This corruption takes     place during the error handling routines within
    __sys_recvmmsg() function.(CVE-2016-7117i1/4%0

  - arch/x86/kvm/vmx.c in the Linux kernel through 4.6.3     mishandles the APICv on/off state, which allows guest     OS users to obtain direct APIC MSR access on the host     OS, and consequently cause a denial of service (host OS     crash) or possibly execute arbitrary code on the host     OS, via x2APIC mode.(CVE-2016-4440i1/4%0

  - In the Linux kernel before 4.17, a local attacker able     to set attributes on an xfs filesystem could make this     filesystem non-operational until the next mount by     triggering an unchecked error condition during an xfs     attribute change, because xfs_attr_shortform_addname in     fs/xfs/libxfs/xfs_attr.c mishandles ATTR_REPLACE     operations with conversion of an attr from short to     long form.(CVE-2018-18690i1/4%0

  - A flaw was found in the Linux kernel's ext4 filesystem.
    A local user can cause an out-of-bounds write and a     denial of service or unspecified other impact is     possible by mounting and operating a crafted ext4     filesystem image.(CVE-2018-10878i1/4%0

  - Xen 3.3.x through 4.5.x and the Linux kernel through     3.19.1 do not properly restrict access to PCI command     registers, which might allow local guest OS users to     cause a denial of service (non-maskable interrupt and     host crash) by disabling the (1) memory or (2) I/O     decoding for a PCI Express device and then accessing     the device, which triggers an Unsupported Request (UR)     response.(CVE-2015-2150i1/4%0

  - The assoc_array_insert_into_terminal_node() function in     'lib/assoc_array.c' in the Linux kernel before 4.5.3     does not check whether a slot is a leaf, which allows     local users to obtain sensitive information from kernel     memory or cause a denial of service (invalid pointer     dereference and out-of-bounds read) via an application     that uses associative-array data     structures.(CVE-2016-7914i1/4%0

  - It was found that the x86 ISA (Instruction Set     Architecture) is prone to a denial of service attack     inside a virtualized environment in the form of an     infinite loop in the microcode due to the way     (sequential) delivering of benign exceptions such as     #AC (alignment check exception) is handled. A     privileged user inside a guest could use this flaw to     create denial of service conditions on the host     kernel.(CVE-2015-5307i1/4%0

  - An issue was discovered in fs/f2fs/super.c in the Linux     kernel, which does not properly validate secs_per_zone     in a corrupted f2fs image. This may lead to a     divide-by-zero error and a system     crash.(CVE-2018-13100i1/4%0

  - The mISDN_sock_recvmsg function in     drivers/isdn/mISDN/socket.c in the Linux kernel before     3.12.4 does not ensure that a certain length value is     consistent with the size of an associated data     structure, which allows local users to obtain sensitive     information from kernel memory via a (1) recvfrom, (2)     recvmmsg, or (3) recvmsg system call.(CVE-2013-7266i1/4%0

  - A NULL pointer dereference flaw was found in the     rds_iw_laddr_check() function in the Linux kernel's     implementation of Reliable Datagram Sockets (RDS). A     local, unprivileged user could use this flaw to crash     the system.(CVE-2014-2678i1/4%0

  - A flaw was found in the Linux kernel's handling of     packets with the URG flag. Applications using the     splice() and tcp_splice_read() functionality could     allow a remote attacker to force the kernel to enter a     condition in which it could loop     indefinitely.(CVE-2017-6214i1/4%0

  - The kernel_wait4 function in kernel/exit.c in the Linux     kernel before 4.13, 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-2018-10087i1/4%0

  - Heap-based buffer overflow in the private wireless     extensions IOCTL implementation in wlan_hdd_wext.c in     the WLAN (aka Wi-Fi) driver for the Linux kernel 3.x     and 4.x, as used in Qualcomm Innovation Center (QuIC)     Android contributions for MSM devices and other     products, allows attackers to gain privileges via a     crafted application that establishes a packet     filter.(CVE-2015-0569i1/4%0

  - A race condition flaw was found in the Linux kernel's     ext4 file system implementation that allowed a local,     unprivileged user to crash the system by simultaneously     writing to a file and toggling the O_DIRECT flag using     fcntl(F_SETFL) on that file.(CVE-2014-8086i1/4%0

  - The mm_init function in kernel/fork.c in the Linux     kernel before 4.12.10 does not clear the -i1/4zexe_file     member of a new process's mm_struct, allowing a local     attacker to achieve a use-after-free condition and to     induce a kernel memory corruption on the system,     leading to a crash or possibly have unspecified other     impact by running a specially crafted program. Due to     the nature of the flaw, privilege escalation cannot be     fully ruled out, although we feel it is     unlikely.(CVE-2017-17052i1/4%0

  - A buffer overflow flaw was found in the way the Linux     kernel's Intel AES-NI instructions optimized version of     the RFC4106 GCM mode decryption functionality handled     fragmented packets. A remote attacker could use this     flaw to crash, or potentially escalate their privileges     on, a system over a connection with an active AES-GCM     mode IPSec security association.(CVE-2015-3331i1/4%0

  - A flaw was found in the processing of incoming L2CAP     bluetooth commands. Uninitialized stack variables can     be sent to an attacker leaking data in kernel address     space.(CVE-2017-1000410i1/4%0

  - It was found that a remote attacker could use a race     condition flaw in the ath_tx_aggr_sleep() function to     crash the system by creating large network traffic on     the system's Atheros 9k wireless network     adapter.(CVE-2014-2672i1/4%0

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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

  - CVE-2017-5715     Multiple researchers have discovered a vulnerability in     various processors supporting speculative execution,     enabling an attacker controlling an unprivileged process     to read memory from arbitrary addresses, including from     the kernel and all other processes running on the     system.

  This specific attack has been named Spectre variant 2 (branch target   injection) and is mitigated for the x86 architecture (amd64 and   i386) by using the 'retpoline' compiler feature which allows   indirect branches to be isolated from speculative execution.

  - CVE-2017-5753     Multiple researchers have discovered a vulnerability in     various processors supporting speculative execution,     enabling an attacker controlling an unprivileged process     to read memory from arbitrary addresses, including from     the kernel and all other processes running on the     system.

  This specific attack has been named Spectre variant 1 (bounds-check   bypass) and is mitigated by identifying vulnerable code sections   (array bounds checking followed by array access) and replacing the   array access with the speculation-safe array_index_nospec()   function.

  More use sites will be added over time.

  - CVE-2017-17975     Tuba Yavuz reported a use-after-free flaw in the     USBTV007 audio-video grabber driver. A local user could     use this for denial of service by triggering failure of     audio registration.

  - CVE-2017-18193     Yunlei He reported that the f2fs implementation does not     properly handle extent trees, allowing a local user to     cause a denial of service via an application with     multiple threads.

  - CVE-2017-18216     Alex Chen reported that the OCFS2 filesystem failed to     hold a necessary lock during nodemanager sysfs file     operations, potentially leading to a NULL pointer     dereference. A local user could use this for denial of     service.

  - CVE-2017-18218     Jun He reported a use-after-free flaw in the Hisilicon     HNS ethernet driver. A local user could use this for     denial of service.

  - CVE-2017-18222     It was reported that the Hisilicon Network Subsystem     (HNS) driver implementation does not properly handle     ethtool private flags. A local user could use this for     denial of service or possibly have other impact.

  - CVE-2017-18224     Alex Chen reported that the OCFS2 filesystem omits the     use of a semaphore and consequently has a race condition     for access to the extent tree during read operations in     DIRECT mode. A local user could use this for denial of     service.

  - CVE-2017-18241     Yunlei He reported that the f2fs implementation does not     properly initialise its state if the 'noflush_merge'     mount option is used. A local user with access to a     filesystem mounted with this option could use this to     cause a denial of service.

  - CVE-2017-18257     It was reported that the f2fs implementation is prone to     an infinite loop caused by an integer overflow in the
    __get_data_block() function. A local user can use this     for denial of service via crafted use of the open and     fallocate system calls with an FS_IOC_FIEMAP ioctl.

  - CVE-2018-1065     The syzkaller tool found a NULL pointer dereference flaw     in the netfilter subsystem when handling certain     malformed iptables rulesets. A local user with the     CAP_NET_RAW or CAP_NET_ADMIN capability (in any user     namespace) could use this to cause a denial of service.
    Debian disables unprivileged user namespaces by default.

  - CVE-2018-1066     Dan Aloni reported to Red Hat that the CIFS client     implementation would dereference a NULL pointer if the     server sent an invalid response during NTLMSSP setup     negotiation. This could be used by a malicious server     for denial of service.

  - CVE-2018-1068     The syzkaller tool found that the 32-bit compatibility     layer of ebtables did not sufficiently validate offset     values. On a 64-bit kernel, a local user with the     CAP_NET_ADMIN capability (in any user namespace) could     use this to overwrite kernel memory, possibly leading to     privilege escalation. Debian disables unprivileged user     namespaces by default.

  - CVE-2018-1092     Wen Xu reported that a crafted ext4 filesystem image     would trigger a null dereference when mounted. A local     user able to mount arbitrary filesystems could use this     for denial of service.

  - CVE-2018-1093     Wen Xu reported that a crafted ext4 filesystem image     could trigger an out-of-bounds read in the     ext4_valid_block_bitmap() function. A local user able to     mount arbitrary filesystems could use this for denial of     service.

  - CVE-2018-1108     Jann Horn reported that crng_ready() does not properly     handle the crng_init variable states and the RNG could     be treated as cryptographically safe too early after     system boot.

  - CVE-2018-5803     Alexey Kodanev reported that the SCTP protocol did not     range-check the length of chunks to be created. A local     or remote user could use this to cause a denial of     service.

  - CVE-2018-7480     Hou Tao discovered a double-free flaw in the     blkcg_init_queue() function in block/blk-cgroup.c. A     local user could use this to cause a denial of service     or have other impact.

  - CVE-2018-7566     Fan LongFei reported a race condition in the ALSA     (sound) sequencer core, between write and ioctl     operations. This could lead to an out-of-bounds access     or use-after-free. A local user with access to a     sequencer device could use this for denial of service or     possibly for privilege escalation.

  - CVE-2018-7740     Nic Losby reported that the hugetlbfs filesystem's mmap     operation did not properly range-check the file offset.
    A local user with access to files on a hugetlbfs     filesystem could use this to cause a denial of service.

  - CVE-2018-7757     Jason Yan reported a memory leak in the SAS     (Serial-Attached SCSI) subsystem. A local user on a     system with SAS devices could use this to cause a denial     of service.

  - CVE-2018-7995     Seunghun Han reported a race condition in the x86 MCE     (Machine Check Exception) driver. This is unlikely to     have any security impact.

  - CVE-2018-8087     A memory leak flaw was found in the hwsim_new_radio_nl()     function in the simulated radio testing tool driver for     mac80211, allowing a local user to cause a denial of     service.

  - CVE-2018-8781     Eyal Itkin reported that the udl (DisplayLink) driver's     mmap operation did not properly range-check the file     offset. A local user with access to a udl framebuffer     device could exploit this to overwrite kernel memory,     leading to privilege escalation.

  - CVE-2018-8822     Dr Silvio Cesare of InfoSect reported that the ncpfs     client implementation did not validate reply lengths     from the server. An ncpfs server could use this to cause     a denial of service or remote code execution in the     client.

  - CVE-2018-10323     Wen Xu reported a NULL pointer dereference flaw in the     xfs_bmapi_write() function triggered when mounting and     operating a crafted xfs filesystem image. A local user     able to mount arbitrary filesystems could use this for     denial of service.

  - CVE-2018-1000199     Andy Lutomirski discovered that the ptrace subsystem did     not sufficiently validate hardware breakpoint settings.
    Local users can use this to cause a denial of service,     or possibly for privilege escalation, on x86 (amd64 and     i386) and possibly other architectures.
