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 kernel package contains the Linux kernel (vmlinuz),     the core of any Linux operating system. The kernel     handles the basic functions of the operating system:
    memory allocation, process allocation, device input and     output, etc.Security Fix(es):A flaw named FragmentSmack     was found in the way the Linux kernel handled     reassembly of fragmented IPv4 and IPv6 packets. A     remote attacker could use this flaw to trigger time and     calculation expensive fragment reassembly algorithm by     sending specially crafted packets which could lead to a     CPU saturation and hence a denial of service on the     system.(CVE-2018-5391)Multiple out-of-bounds write     flaws were found in the way the Cherry Cymotion     keyboard driver, KYE/Genius device drivers, Logitech     device drivers, Monterey Genius KB29E keyboard driver,     Petalynx Maxter remote control driver, and Sunplus     wireless desktop driver handled HID reports with an     invalid report descriptor size. An attacker with     physical access to the system could use either of these     flaws to write data past an allocated memory     buffer.(CVE-2014-3184)The __get_data_block function in     fs/f2fs/data.c in the Linux kernel before 4.11 allows     local users to cause a denial of service (integer     overflow and loop) via crafted use of the open and     fallocate system calls with an FS_IOC_FIEMAP     ioctl.(CVE-2017-18257)netetfilter/xt_osf.c in the Linux     kernel through 4.14.4 does not require the     CAP_NET_ADMIN capability for add_callback and     remove_callback operations. This allows local users to     bypass intended access restrictions because the     xt_osf_fingers data structure is shared across all     network namespaces.(CVE-2017-17450)A denial of service     flaw was discovered in the Linux kernel, where a race     condition caused a NULL pointer dereference in the RDS     socket-creation code. A local attacker could use this     flaw to create a situation in which a NULL pointer     crashed the kernel.(CVE-2015-7990)An issue was     discovered in the Linux kernel before 4.19.9. The USB     subsystem mishandles size checks during the reading of     an extra descriptor, related to
    __usb_get_extra_descriptor in     drivers/usb/core/usb.c.(CVE-2018-20169)mm/memory.c in     the Linux kernel before 4.1.4 mishandles anonymous     pages, which allows local users to gain privileges or     cause a denial of service (page tainting) via a crafted     application that triggers writing to page     zero.(CVE-2015-3288)The ovl_setattr function in     fs/overlayfs/inode.c in the Linux kernel through 4.3.3     attempts to merge distinct setattr operations, which     allows local users to bypass intended access     restrictions and modify the attributes of arbitrary     overlay files via a crafted     application.(CVE-2015-8660)A flaw was found in the     Linux kernel where a local user with a shell account     can abuse the userfaultfd syscall when using hugetlbfs.
    A missing size check in hugetlb_mcopy_atomic_pte could     create an invalid inode variable, leading to a kernel     panic.(CVE-2017-15128)An integer overflow flaw was     found in the way the lzo1x_decompress_safe() function     of the Linux kernel's LZO implementation processed     Literal Runs. A local attacker could, in extremely rare     cases, use this flaw to crash the system or,     potentially, escalate their privileges on the     system.(CVE-2014-4608)It was found that Linux kernel's     ptrace subsystem did not properly sanitize the     address-space-control bits when the program-status word     (PSW) was being set. On IBM S/390 systems, a local,     unprivileged user could use this flaw to set     address-space-control bits to the kernel space, and     thus gain read and write access to kernel     memory.(CVE-2014-3534)A use-after-free flaw was found     in the Linux kernel's file system encryption     implementation. A local user could revoke keyring keys     being used for ext4, f2fs, or ubifs encryption, causing     a denial of service on the system.(CVE-2017-7374)The     usbip_recv_xbuff function in     drivers/usb/usbip/usbip_common.c in the Linux kernel     before 4.5.3 allows remote attackers to cause a denial     of service (out-of-bounds write) or possibly have     unspecified other impact via a crafted length value in     a USB/IP packet.(CVE-2016-3955)A flaw was found in the     patches used to fix the 'dirtycow' vulnerability     (CVE-2016-5195). An attacker, able to run local code,     can exploit a race condition in transparent huge pages     to modify usually read-only huge     pages.(CVE-2017-1000405)The aio_mount function in     fs/aio.c in the Linux kernel does not properly restrict     execute access, which makes it easier for local users     to bypass intended SELinux W^X policy     restrictions.(CVE-2016-10044)The Serial Attached SCSI     (SAS) implementation in the Linux kernel mishandles a     mutex within libsas. This allows local users to cause a     denial of service (deadlock) by triggering certain     error-handling code.(CVE-2017-18232)A use-after-free     vulnerability was found in tcp_xmit_retransmit_queue     and other tcp_* functions. This condition could allow     an attacker to send an incorrect selective     acknowledgment to existing connections, possibly     resetting a connection.(CVE-2016-6828)The instruction     decoder in arch/x86/kvm/emulate.c in the KVM subsystem     in the Linux kernel before 3.18-rc2 does not properly     handle invalid instructions, which allows guest OS     users to cause a denial of service (NULL pointer     dereference and host OS crash) via a crafted     application that triggers (1) an improperly fetched     instruction or (2) an instruction that occupies too     many bytes. NOTE: this vulnerability exists because of     an incomplete fix for CVE-2014-8480.(CVE-2014-8481)The     snd_compress_check_input function in     sound/core/compress_offload.c in the ALSA subsystem in     the Linux kernel before 3.17 does not properly check     for an integer overflow, which allows local users to     cause a denial of service (insufficient memory     allocation) or possibly have unspecified other impact     via a crafted SNDRV_COMPRESS_SET_PARAMS ioctl     call.(CVE-2014-9904)The resv_map_release function in     mm/hugetlb.c in the Linux kernel, through 4.15.7,     allows local users to cause a denial of service (BUG)     via a crafted application that makes mmap system calls     and has a large pgoff argument to the remap_file_pages     system call.(CVE-2018-7740)

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

  - A use-after-free flaw was found in the way the Linux     kernel's key management subsystem handled keyring     object reference counting in certain error path of the     join_session_keyring() function. A local, unprivileged     user could use this flaw to escalate their privileges     on the system.(CVE-2016-0728)

  - A flaw was found in the way the Linux kernel's ASN.1     DER decoder processed certain certificate files with     tags of indefinite length. A local, unprivileged user     could use a specially crafted X.509 certificate DER     file to crash the system or, potentially, escalate     their privileges on the system.(CVE-2016-0758)

  - The LIST_POISON feature in include/linux/poison.h in     the Linux kernel before 4.3, as used in Android 6.0.1     before 2016-03-01, does not properly consider the     relationship to the mmap_min_addr value, which makes it     easier for attackers to bypass a poison-pointer     protection mechanism by triggering the use of an     uninitialized list entry, aka Android internal bug     26186802, a different vulnerability than     CVE-2015-3636.(CVE-2016-0821)

  - The pagemap_open function in fs/proc/task_mmu.c in the     Linux kernel before 3.19.3, as used in Android 6.0.1     before 2016-03-01, allows local users to obtain     sensitive physical-address information by reading a     pagemap file, aka Android internal bug     25739721.(CVE-2016-0823)

  - The aio_mount function in fs/aio.c in the Linux kernel     does not properly restrict execute access, which makes     it easier for local users to bypass intended SELinux     W^X policy restrictions.(CVE-2016-10044)

  - It was found that the fix for CVE-2016-9576 was     incomplete: the Linux kernel's sg implementation did     not properly restrict write operations in situations     where the KERNEL_DS option is set. A local attacker to     read or write to arbitrary kernel memory locations or     cause a denial of service (use-after-free) by     leveraging write access to a /dev/sg     device.(CVE-2016-10088)

  - A use-after-free flaw was found in the Linux kernel     which enables a race condition in the L2TPv3 IP     Encapsulation feature. A local user could use this flaw     to escalate their privileges or crash the     system.(CVE-2016-10200)

  - Mounting a crafted EXT4 image read-only leads to an     attacker controlled memory corruption and     SLAB-Out-of-Bounds reads.(CVE-2016-10208)

  - The Linux kernel allows remote attackers to execute     arbitrary code via UDP traffic that triggers an unsafe     second checksum calculation during execution of a recv     system call with the MSG_PEEK flag. This may create a     kernel panic or memory corruption leading to privilege     escalation.(CVE-2016-10229)

  - The overlayfs implementation in the Linux kernel     through 4.5.2 does not properly maintain POSIX ACL     xattr data, which allows local users to gain privileges     by leveraging a group-writable setgid     directory.(CVE-2016-1575)

  - The overlayfs implementation in the Linux kernel     through 4.5.2 does not properly restrict the mount     namespace, which allows local users to gain privileges     by mounting an overlayfs filesystem on top of a FUSE     filesystem, and then executing a crafted setuid     program.(CVE-2016-1576)

  - A syntax vulnerability was discovered in the kernel's     ASN1.1 DER decoder, which could lead to memory     corruption or a complete local denial of service     through x509 certificate DER files. A local system user     could use a specially created key file to trigger     BUG_ON() in the public_key_verify_signature() function     (crypto/asymmetric_keys/public_key.c), to cause a     kernel panic and crash the system.(CVE-2016-2053)

  - A flaw was discovered in the way the Linux kernel dealt     with paging structures. When the kernel invalidated a     paging structure that was not in use locally, it could,     in principle, race against another CPU that is     switching to a process that uses the paging structure     in question. A local user could use a thread running     with a stale cached virtual-i1/4zphysical translation to     potentially escalate their privileges if the     translation in question were writable and the physical     page got reused for something critical (for example, a     page table).(CVE-2016-2069)

  - A divide-by-zero vulnerability was found in a way the     kernel processes TCP connections. The error can occur     if a connection starts another cwnd reduction phase by     setting tp-i1/4zprior_cwnd to the current cwnd (0) in     tcp_init_cwnd_reduction(). A remote, unauthenticated     attacker could use this flaw to crash the kernel     (denial of service).(CVE-2016-2070)

  - 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)

  - The create_fixed_stream_quirk function in     sound/usb/quirks.c in the snd-usb-audio driver in the     Linux kernel before 4.5.1 allows physically proximate     attackers to cause a denial of service (NULL pointer     dereference or double free, and system crash) via a     crafted endpoints value in a USB device     descriptor.(CVE-2016-2184)

  - 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-2016-2185)

  - 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)

  - The gtco_probe function in drivers/input/tablet/gtco.c     in the Linux kernel through 4.5.2 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-2016-2187)

  - 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-2016-2188)

  - A flaw was found in the USB-MIDI Linux kernel driver: a     double-free error could be triggered for the 'umidi'     object. An attacker with physical access to the system     could use this flaw to escalate their     privileges.(CVE-2016-2384)

  - The snd_seq_ioctl_remove_events function in     sound/core/seq/seq_clientmgr.c in the Linux kernel     before 4.4.1 does not verify FIFO assignment before     proceeding with FIFO clearing, which allows local users     to cause a denial of service (NULL pointer dereference     and OOPS) via a crafted ioctl call.(CVE-2016-2543)

  - Race condition in the queue_delete function in     sound/core/seq/seq_queue.c in the Linux kernel before     4.4.1 allows local users to cause a denial of service     (use-after-free and system crash) by making an ioctl     call at a certain time.(CVE-2016-2544)

  - 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-2017-7616: Incorrect error handling in the     set_mempolicy and mbind compat syscalls in     mm/mempolicy.c in the Linux kernel allowed local users     to obtain sensitive information from uninitialized stack     data by triggering failure of a certain bitmap operation     (bnc#1033336).

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