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 x25_negotiate_facilities function in     net/x25/x25_facilities.c in the Linux kernel before     4.5.5 does not properly initialize a certain data     structure, which allows attackers to obtain sensitive     information from kernel stack memory via an X.25 Call     Request.(CVE-2016-4580i1/4%0

  - A flaw was found in the Linux kernel's implementation     of seq_file where a local attacker could manipulate     memory in the put() function pointer. This could lead     to memory corruption and possible privileged     escalation.(CVE-2016-7910i1/4%0

  - A flaw was found in the way the Linux kernel's     netfilter subsystem handled generic protocol tracking.
    As demonstrated in the Stream Control Transmission     Protocol (SCTP) case, a remote attacker could use this     flaw to bypass intended iptables rule restrictions when     the associated connection tracking module was not     loaded on the system.(CVE-2014-8160i1/4%0

  - The get_endpoints function in     drivers/usb/misc/usbtest.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-2017-16532i1/4%0

  - An integer overflow flaw was found in the way the Linux     kernel's Advanced Linux Sound Architecture (ALSA)     implementation handled user controls. A local,     privileged user could use this flaw to crash the     system.(CVE-2014-4656i1/4%0

  - The sr_do_ioctl function in drivers/scsi/sr_ioctl.c in     the Linux kernel through 4.16.12 allows local users to     cause a denial of service (stack-based buffer overflow)     or possibly have unspecified other impact because sense     buffers have different sizes at the CDROM layer and the     SCSI layer.(CVE-2018-11506i1/4%0

  - A race condition flaw was found in the way the Linux     kernel's SCTP implementation handled Address     Configuration lists when performing Address     Configuration Change (ASCONF). A local attacker could     use this flaw to crash the system via a race condition     triggered by setting certain ASCONF options on a     socket.(CVE-2015-3212i1/4%0

  - 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-2014-9729i1/4%0

  - The Linux kernel before version 4.11 is vulnerable to a     NULL pointer dereference in     fs/cifs/cifsencrypt.c:setup_ntlmv2_rsp() that allows an     attacker controlling a CIFS server to kernel panic a     client that has this server mounted, because an empty     TargetInfo field in an NTLMSSP setup negotiation     response is mishandled during session     recovery.(CVE-2018-1066i1/4%0

  - drivers/hid/hid-sensor-hub.c in the Human Interface     Device (HID) subsystem in the Linux kernel through     3.11, when CONFIG_HID_SENSOR_HUB is enabled, allows     physically proximate attackers to obtain sensitive     information from kernel memory via a crafted     device.(CVE-2013-2898i1/4%0

  - An issue was discovered in the Linux kernel's F2FS     filesystem code. A buffer overflow in     truncate_inline_inode() in the fs/f2fs/inline.c     function, when umounting a crafted f2fs image, can     occur because a length value may be     negative.(CVE-2018-14615i1/4%0

  - The help function in net/netfilter/nf_nat_irc.c in the     Linux kernel before 3.12.8 allows remote attackers to     obtain sensitive information from kernel memory by     establishing an IRC DCC session in which incorrect     packet data is transmitted during use of the NAT mangle     feature.(CVE-2014-1690i1/4%0

  - It was found that the Linux kernel's keys subsystem did     not correctly garbage collect uninstantiated keyrings.
    A local attacker could use this flaw to crash the     system or, potentially, escalate their privileges on     the system.(CVE-2015-7872i1/4%0

  - The TCP stack in the Linux kernel 3.x does not properly     implement a SYN cookie protection mechanism for the     case of a fast network connection, which allows remote     attackers to cause a denial of service (CPU     consumption) by sending many TCP SYN packets, as     demonstrated by an attack against the kernel-3.10.0     package in CentOS Linux 7. NOTE: third parties have     been unable to discern any relationship between the     GitHub Engineering finding and the Trigemini.c attack     code.(CVE-2017-5972i1/4%0

  - The xfrm_migrate() function in the     net/xfrm/xfrm_policy.c file in the Linux kernel built     with CONFIG_XFRM_MIGRATE does not verify if the dir     parameter is less than XFRM_POLICY_MAX. This allows a     local attacker to cause a denial of service     (out-of-bounds access) or possibly have unspecified     other impact by sending a XFRM_MSG_MIGRATE netlink     message. This flaw is present in the Linux kernel since     an introduction of XFRM_MSG_MIGRATE in 2.6.21-rc1, up     to 4.13-rc3.(CVE-2017-11600i1/4%0

Multiple vulnerabilities has been found and corrected in the Linux kernel :

Multiple buffer overflows in drivers/staging/wlags49_h2/wl_priv.c in the Linux kernel before 3.12 allow local users to cause a denial of service or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability and providing a long station-name string, related to the (1) wvlan_uil_put_info and (2) wvlan_set_station_nickname functions (CVE-2013-4514).

Use-after-free vulnerability in the skb_segment function in net/core/skbuff.c in the Linux kernel through 3.13.6 allows attackers to obtain sensitive information from kernel memory by leveraging the absence of a certain orphaning operation (CVE-2014-0131).

The rd_build_device_space function in drivers/target/target_core_rd.c in the Linux kernel before 3.14 does not properly initialize a certain data structure, which allows local users to obtain sensitive information from ramdisk_mcp memory by leveraging access to a SCSI initiator (CVE-2014-4027).

Multiple integer overflows in the lzo1x_decompress_safe function in lib/lzo/lzo1x_decompress_safe.c in the LZO decompressor in the Linux kernel before 3.15.2 allow context-dependent attackers to cause a denial of service (memory corruption) via a crafted Literal Run (CVE-2014-4608).

Race condition in the tlv handler functionality in the snd_ctl_elem_user_tlv function in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 allows local users to obtain sensitive information from kernel memory by leveraging /dev/snd/controlCX access (CVE-2014-4652).

sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 does not ensure possession of a read/write lock, which allows local users to cause a denial of service (use-after-free) and obtain sensitive information from kernel memory by leveraging /dev/snd/controlCX access (CVE-2014-4653).

The snd_ctl_elem_add function in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 does not check authorization for SNDRV_CTL_IOCTL_ELEM_REPLACE commands, which allows local users to remove kernel controls and cause a denial of service (use-after-free and system crash) by leveraging /dev/snd/controlCX access for an ioctl call (CVE-2014-4654).

The snd_ctl_elem_add function in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 does not properly maintain the user_ctl_count value, which allows local users to cause a denial of service (integer overflow and limit bypass) by leveraging /dev/snd/controlCX access for a large number of SNDRV_CTL_IOCTL_ELEM_REPLACE ioctl calls (CVE-2014-4655).

Multiple integer overflows in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 allow local users to cause a denial of service by leveraging /dev/snd/controlCX access, related to (1) index values in the snd_ctl_add function and (2) numid values in the snd_ctl_remove_numid_conflict function (CVE-2014-4656).

The sctp_association_free function in net/sctp/associola.c in the Linux kernel before 3.15.2 does not properly manage a certain backlog value, which allows remote attackers to cause a denial of service (socket outage) via a crafted SCTP packet (CVE-2014-4667).

The Linux kernel before 3.15.4 on Intel processors does not properly restrict use of a non-canonical value for the saved RIP address in the case of a system call that does not use IRET, which allows local users to leverage a race condition and gain privileges, or cause a denial of service (double fault), via a crafted application that makes ptrace and fork system calls (CVE-2014-4699).

The PPPoL2TP feature in net/l2tp/l2tp_ppp.c in the Linux kernel through 3.15.6 allows local users to gain privileges by leveraging data-structure differences between an l2tp socket and an inet socket (CVE-2014-4943).

The updated packages provides a solution for these security issues.
