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 :

  - It was found that the parse_rock_ridge_inode_internal()     function of the Linux kernel's ISOFS implementation did     not correctly check relocated directories when     processing Rock Ridge child link (CL) tags. An attacker     with physical access to the system could use a     specially crafted ISO image to crash the system or,     potentially, escalate their privileges on the     system.(CVE-2014-5472)

  - An issue was discovered in the Linux kernel's F2FS     filesystem code. An out-of-bounds access vulnerability     is possible the in __remove_dirty_segment() in     fs/f2fs/segment.c function when mounting a crafted f2fs     image.(CVE-2018-14614)

  - Race condition in kernel/events/core.c in the Linux     kernel before 4.4 allows local users to gain privileges     or cause a denial of service via use-after-free     vulnerability by leveraging incorrect handling of an     swevent data structure during a CPU unplug     operation.(CVE-2015-8963)

  - The skbs processed by ip_cmsg_recv() are not guaranteed     to be linear (e.g. when sending UDP packets over     loopback with MSGMORE). Using csum_partial() on     potentially the whole skb len is dangerous; instead be     on the safe side and use skb_checksum(). This may lead     to an infoleak as the kernel memory may be checksummed     and sent as part of the packet.(CVE-2017-6347)

  - The apic_get_tmcct function in arch/x86/kvm/lapic.c in     the KVM subsystem in the Linux kernel through 3.12.5     allows guest OS users to cause a denial of service     (divide-by-zero error and host OS crash) via crafted     modifications of the TMICT value.(CVE-2013-6367)

  - A use-after-free issue was found in the way the Linux     kernel's KVM hypervisor processed posted interrupts     when nested(=1) virtualization is enabled. In     nested_get_vmcs12_pages(), in case of an error while     processing posted interrupt address, it unmaps the     'pi_desc_page' without resetting 'pi_desc' descriptor     address, which is later used in pi_test_and_clear_on().
    A guest user/process could use this flaw to crash the     host kernel resulting in DoS or potentially gain     privileged access to a system.(CVE-2018-16882)

  - It was discovered that the atl2_probe() function in the     Atheros L2 Ethernet driver in the Linux kernel     incorrectly enabled scatter/gather I/O. A remote     attacker could use this flaw to obtain potentially     sensitive information from the kernel     memory.(CVE-2016-2117)

  - 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)

  - The powermate_probe function in     drivers/input/misc/powermate.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-2016-2186)

  - It was found that KVM's Write to Model Specific     Register (WRMSR) instruction emulation would write     non-canonical values passed in by the guest to certain     MSRs in the host's context. A privileged guest user     could use this flaw to crash the host.(CVE-2014-3610)

  - The BPF_S_ANC_NLATTR_NEST extension implementation in     the sk_run_filter function in net/core/filter.c in the     Linux kernel through 3.14.3 uses the reverse order in a     certain subtraction, which allows local users to cause     a denial of service (over-read and system crash) via     crafted BPF instructions. NOTE: the affected code was     moved to the __skb_get_nlattr_nest function before the     vulnerability was announced.(CVE-2014-3145)

  - The yam_ioctl function in drivers/net/hamradio/yam.c in     the Linux kernel before 3.12.8 does not initialize a     certain structure member, which allows local users to     obtain sensitive information from kernel memory by     leveraging the CAP_NET_ADMIN capability for an     SIOCYAMGCFG ioctl call.(CVE-2014-1446)

  - A race condition flaw was found in the N_HLDC Linux     kernel driver when accessing n_hdlc.tbuf list that can     lead to double free. A local, unprivileged user able to     set the HDLC line discipline on the tty device could     use this flaw to increase their privileges on the     system.(CVE-2017-2636)

  - A flaw was found in the way Linux kernel's Transparent     Huge Pages (THP) implementation handled non-huge page     migration. A local, unprivileged user could use this     flaw to crash the kernel by migrating transparent     hugepages.(CVE-2014-3940)

  - A security flaw was found in the     chap_server_compute_md5() function in the ISCSI target     code in the Linux kernel in a way an authentication     request from an ISCSI initiator is processed. An     unauthenticated remote attacker can cause a stack     buffer overflow and smash up to 17 bytes of the stack.
    The attack requires the iSCSI target to be enabled on     the victim host. Depending on how the target's code was     built (i.e. depending on a compiler, compile flags and     hardware architecture) an attack may lead to a system     crash and thus to a denial of service or possibly to a     non-authorized access to data exported by an iSCSI     target. Due to the nature of the flaw, privilege     escalation cannot be fully ruled out, although we     believe it is highly unlikely.(CVE-2018-14633)

  - A vulnerability was found in the Linux kernel where     filesystems mounted with data=ordered mode may allow an     attacker to read stale data from recently allocated     blocks in new files after a system 'reset' by abusing     ext4 mechanics of delayed allocation.(CVE-2017-7495)

  - drivers/media/platform/msm/broadcast/tsc.c in the TSC     driver for the Linux kernel 3.x, as used in Qualcomm     Innovation Center (QuIC) Android contributions for MSM     devices and other products, allows attackers to cause a     denial of service (invalid pointer dereference) or     possibly have unspecified other impact via a crafted     application that makes a TSC_GET_CARD_STATUS ioctl     call.(CVE-2015-0573)

  - It was found that the unlink and rename functionality     in overlayfs did not verify the upper dentry for     staleness. A local, unprivileged user could use the     rename syscall on overlayfs on top of xfs to panic or     crash the system.(CVE-2016-6197)

  - In net/socket.c in the Linux kernel through 4.17.1,     there is a race condition between fchownat and close in     cases where they target the same socket file     descriptor, related to the sock_close and     sockfs_setattr functions. fchownat does not increment     the file descriptor reference count, which allows close     to set the socket to NULL during fchownat's execution,     leading to a NULL pointer dereference and system     crash.(CVE-2018-12232)

  - The ath9k_htc_set_bssid_mask function in     drivers/net/wireless/ath/ath9k/htc_drv_main.c in the     Linux kernel through 3.12 uses a BSSID masking approach     to determine the set of MAC addresses on which a Wi-Fi     device is listening, which allows remote attackers to     discover the original MAC address after spoofing by     sending a series of packets to MAC addresses with     certain bit manipulations.(CVE-2013-4579)

The SUSE Linux Enterprise 12 SP2 kernel was updated to 4.4.58 to receive various security and bugfixes. Notable new/improved features :

  - Improved support for Hyper-V

  - Support for Matrox G200eH3

  - Support for tcp_westwood The following security bugs     were fixed :

  - CVE-2017-2671: The ping_unhash function in     net/ipv4/ping.c in the Linux kernel was too late in     obtaining a certain lock and consequently could not     ensure that disconnect function calls are safe, which     allowed local users to cause a denial of service (panic)     by leveraging access to the protocol value of     IPPROTO_ICMP in a socket system call (bnc#1031003).

  - CVE-2017-7308: The packet_set_ring function in     net/packet/af_packet.c in the Linux kernel did not     properly validate certain block-size data, which allowed     local users to cause a denial of service (overflow) or     possibly have unspecified other impact via crafted     system calls (bnc#1031579).

  - CVE-2017-7294: The vmw_surface_define_ioctl function in     drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux     kernel did not validate addition of certain levels data,     which allowed local users to trigger an integer overflow     and out-of-bounds write, and cause a denial of service     (system hang or crash) or possibly gain privileges, via     a crafted ioctl call for a /dev/dri/renderD* device     (bnc#1031440).

  - CVE-2017-7261: The vmw_surface_define_ioctl function in     drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux     kernel did not check for a zero value of certain levels     data, which allowed local users to cause a denial of     service (ZERO_SIZE_PTR dereference, and GPF and possibly     panic) via a crafted ioctl call for a /dev/dri/renderD*     device (bnc#1031052).

  - CVE-2017-7187: The sg_ioctl function in     drivers/scsi/sg.c in the Linux kernel allowed local     users to cause a denial of service (stack-based buffer     overflow) or possibly have unspecified other impact 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 (bnc#1030213).

  - CVE-2017-7374: Use-after-free vulnerability in     fs/crypto/ in the Linux kernel allowed local users to     cause a denial of service (NULL pointer dereference) or     possibly gain privileges by revoking keyring keys being     used for ext4, f2fs, or ubifs encryption, causing     cryptographic transform objects to be freed prematurely     (bnc#1032006).

  - CVE-2016-10200: Race condition in the L2TPv3 IP     Encapsulation feature in the Linux kernel allowed local     users to gain privileges or cause a denial of service     (use-after-free) by making multiple bind system calls     without properly ascertaining whether a socket has the     SOCK_ZAPPED status, related to net/l2tp/l2tp_ip.c and     net/l2tp/l2tp_ip6.c (bnc#1028415).

  - CVE-2017-6345: The LLC subsystem in the Linux kernel did     not ensure that a certain destructor exists in required     circumstances, which allowed local users to cause a     denial of service (BUG_ON) or possibly have unspecified     other impact via crafted system calls (bnc#1027190).

  - CVE-2017-6346: Race condition in net/packet/af_packet.c     in the Linux kernel allowed local users to cause a     denial of service (use-after-free) or possibly have     unspecified other impact via a multithreaded application     that made PACKET_FANOUT setsockopt system calls     (bnc#1027189).

  - CVE-2017-6353: net/sctp/socket.c in the Linux kernel did     not properly restrict association peel-off operations     during certain wait states, which allowed local users to     cause a denial of service (invalid unlock and double     free) via a multithreaded application. NOTE: this     vulnerability exists because of an incorrect fix for     CVE-2017-5986 (bnc#1027066).

  - CVE-2017-6214: The tcp_splice_read function in     net/ipv4/tcp.c in the Linux kernel allowed remote     attackers to cause a denial of service (infinite loop     and soft lockup) via vectors involving a TCP packet with     the URG flag (bnc#1026722).

  - CVE-2016-2117: The atl2_probe function in     drivers/net/ethernet/atheros/atlx/atl2.c in the Linux     kernel incorrectly enables scatter/gather I/O, which     allowed remote attackers to obtain sensitive information     from kernel memory by reading packet data (bnc#968697).

  - CVE-2017-6347: The ip_cmsg_recv_checksum function in     net/ipv4/ip_sockglue.c in the Linux kernel had incorrect     expectations about skb data layout, which allowed local     users to cause a denial of service (buffer over-read) or     possibly have unspecified other impact via crafted     system calls, as demonstrated by use of the MSG_MORE     flag in conjunction with loopback UDP transmission     (bnc#1027179).

  - CVE-2016-9191: The cgroup offline implementation in the     Linux kernel mishandled certain drain operations, which     allowed local users to cause a denial of service (system     hang) by leveraging access to a container environment     for executing a crafted application (bnc#1008842).

  - CVE-2017-2596: The nested_vmx_check_vmptr function in     arch/x86/kvm/vmx.c in the Linux kernel improperly     emulated the VMXON instruction, which allowed KVM L1     guest OS users to cause a denial of service (host OS     memory consumption) by leveraging the mishandling of     page references (bnc#1022785).

  - CVE-2017-6074: The dccp_rcv_state_process function in     net/dccp/input.c in the Linux kernel mishandled     DCCP_PKT_REQUEST packet data structures in the LISTEN     state, which allowed local users to obtain root     privileges or cause a denial of service (double free)     via an application that made an IPV6_RECVPKTINFO     setsockopt system call (bnc#1026024).

The update package also includes non-security fixes. See advisory for details.

The openSUSE Leap 42.1 kernel was updated to 4.1.39 to receive various security and bugfixes.

The following security bugs were fixed :

  - CVE-2017-5669: The do_shmat function in ipc/shm.c in the     Linux kernel did not restrict the address calculated by     a certain rounding operation, which allowed local users     to map page zero, and consequently bypass a protection     mechanism that exists for the mmap system call, by     making crafted shmget and shmat system calls in a     privileged context (bnc#1026914).

  - CVE-2017-6348: The hashbin_delete function in     net/irda/irqueue.c in the Linux kernel improperly     manages lock dropping, which allowed local users to     cause a denial of service (deadlock) via crafted     operations on IrDA devices (bnc#1027178).

  - CVE-2017-7184: The xfrm_replay_verify_len function in     net/xfrm/xfrm_user.c in the Linux kernel did not     validate certain size data after an XFRM_MSG_NEWAE     update, which allowed local users to obtain root     privileges or cause a denial of service (heap-based     out-of-bounds access) by leveraging the CAP_NET_ADMIN     capability, as demonstrated during a Pwn2Own competition     at CanSecWest 2017 for the Ubuntu 16.10 linux-image-*     package 4.8.0.41.52 (bnc#1030573).

  - CVE-2016-10200: Race condition in the L2TPv3 IP     Encapsulation feature in the Linux kernel allowed local     users to gain privileges or cause a denial of service     (use-after-free) by making multiple bind system calls     without properly ascertaining whether a socket has the     SOCK_ZAPPED status, related to net/l2tp/l2tp_ip.c and     net/l2tp/l2tp_ip6.c (bnc#1028415).

  - CVE-2017-2636: Race condition in drivers/tty/n_hdlc.c in     the Linux kernel allowed local users to gain privileges     or cause a denial of service (double free) by setting     the HDLC line discipline (bnc#1027565).

  - CVE-2017-6345: The LLC subsystem in the Linux kernel did     not ensure that a certain destructor exists in required     circumstances, which allowed local users to cause a     denial of service (BUG_ON) or possibly have unspecified     other impact via crafted system calls (bnc#1027190).

  - CVE-2017-6346: Race condition in net/packet/af_packet.c     in the Linux kernel allowed local users to cause a     denial of service (use-after-free) or possibly have     unspecified other impact via a multithreaded application     that made PACKET_FANOUT setsockopt system calls     (bnc#1027189).

  - CVE-2017-6347: The ip_cmsg_recv_checksum function in     net/ipv4/ip_sockglue.c in the Linux kernel has incorrect     expectations about skb data layout, which allowed local     users to cause a denial of service (buffer over-read) or     possibly have unspecified other impact via crafted     system calls, as demonstrated by use of the MSG_MORE     flag in conjunction with loopback UDP transmission     (bnc#1027179).

  - CVE-2017-6353: net/sctp/socket.c in the Linux kernel did     not properly restrict association peel-off operations     during certain wait states, which allowed local users to     cause a denial of service (invalid unlock and double     free) via a multithreaded application. NOTE: this     vulnerability exists because of an incorrect fix for     CVE-2017-5986 (bnc#1025235).

  - CVE-2017-6214: The tcp_splice_read function in     net/ipv4/tcp.c in the Linux kernel allowed remote     attackers to cause a denial of service (infinite loop     and soft lockup) via vectors involving a TCP packet with     the URG flag (bnc#1026722).

  - CVE-2016-2117: The atl2_probe function in     drivers/net/ethernet/atheros/atlx/atl2.c in the Linux     kernel incorrectly enables scatter/gather I/O, which     allowed remote attackers to obtain sensitive information     from kernel memory by reading packet data (bnc#968697).

  - CVE-2016-10208: The ext4_fill_super function in     fs/ext4/super.c in the Linux kernel did not properly     validate meta block groups, which allowed physically     proximate attackers to cause a denial of service     (out-of-bounds read and system crash) via a crafted ext4     image (bnc#1023377).

  - CVE-2017-2596: The nested_vmx_check_vmptr function in     arch/x86/kvm/vmx.c in the Linux kernel improperly     emulates the VMXON instruction, which allowed KVM L1     guest OS users to cause a denial of service (host OS     memory consumption) by leveraging the mishandling of     page references (bnc#1022785).

  - CVE-2017-2583: The load_segment_descriptor     implementation in arch/x86/kvm/emulate.c in the Linux     kernel improperly emulates a 'MOV SS, NULL selector'     instruction, which allowed guest OS users to cause a     denial of service (guest OS crash) or gain guest OS     privileges via a crafted application (bnc#1020602).

  - CVE-2017-2584: arch/x86/kvm/emulate.c in the Linux     kernel allowed 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 (bnc#1019851).

The skbs processed by ip_cmsg_recv() are not guaranteed to be linear (e.g. when sending UDP packets over loopback with MSGMORE). Using csum_partial() on potentially the whole skb len is dangerous; instead be on the safe side and use skb_checksum(). This may lead to an infoleak as the kernel memory may be checksummed and sent as part of the packet. (CVE-2017-6347)

It was discovered that xfrm_replay_verify_len(), as called by xfrm_new_ae(), did not verify that the user-specified replay_window was within the replay state buffer. This allowed for out-of-bounds reads and writes of kernel memory.(CVE-2017-7184)
