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 acpi_smbus_hc_add function in drivers/acpi/sbshc.c     in the Linux kernel through 4.14.15 allows local users     to obtain sensitive address information by reading     dmesg data from an SBS HC printk call.(CVE-2018-5750i1/4%0

  - An issue was discovered in the btrfs filesystem code in     the Linux kernel. A use-after-free is possible in     try_merge_free_space() when mounting a crafted btrfs     image due to a lack of chunk type flag checks in     btrfs_check_chunk_valid() in the fs/btrfs/volumes.c     function. This could lead to a denial of service or     other unspecified impact.(CVE-2018-14611i1/4%0

  - A flaw was found in the way the Linux kernel visor     driver handles certain invalid USB device descriptors.
    The driver assumes that the device always has at least     one bulk OUT endpoint. By using a specially crafted USB     device (without a bulk OUT endpoint), an unprivileged     user with physical access could trigger a kernel     NULL-pointer dereference and cause a system panic     (denial of service).(CVE-2015-7566i1/4%0

  - It was found that the RFC 5961 challenge ACK rate     limiting as implemented in the Linux kernel's     networking subsystem allowed an off-path attacker to     leak certain information about a given connection by     creating congestion on the global challenge ACK rate     limit counter and then measuring the changes by probing     packets. An off-path attacker could use this flaw to     either terminate TCP connection and/or inject payload     into non-secured TCP connection between two endpoints     on the network.(CVE-2016-5696i1/4%0

  - It was found that the Bluebooth Network Encapsulation     Protocol (BNEP) implementation did not validate the     type of second socket passed to the BNEPCONNADD     ioctl(), which could lead to memory corruption. A local     user with the CAP_NET_ADMIN capability can use this for     denial of service (crash or data corruption) or     possibly for privilege escalation. Due to the nature of     the flaw, privilege escalation cannot be fully ruled     out, although we feel it is unlikely.(CVE-2017-15868i1/4%0

  - A vulnerability was found in the key management     subsystem of the Linux kernel. An update on an     uninstantiated key could cause a kernel panic, leading     to denial of service (DoS).(CVE-2017-15299i1/4%0

  - A flaw was found in the alarm_timer_nsleep() function     in kernel/time/alarmtimer.c in the Linux kernel. The     ktime_add_safe() function is not used and an integer     overflow can happen causing an alarm not to fire if     using a large relative timeout.(CVE-2018-13053i1/4%0

  - net/llc/sysctl_net_llc.c in the Linux kernel before     3.19 uses an incorrect data type in a sysctl table,     which allows local users to obtain potentially     sensitive information from kernel memory or possibly     have unspecified other impact by accessing a sysctl     entry.(CVE-2015-2041i1/4%0

  - Incorrect error handling in the set_mempolicy() and     mbind() compat syscalls in 'mm/mempolicy.c' in the     Linux kernel allows local users to obtain sensitive     information from uninitialized stack data by triggering     failure of a certain bitmap operation.(CVE-2017-7616i1/4%0

  - The snd_msnd_interrupt function in     sound/isa/msnd/msnd_pinnacle.c in the Linux kernel     through 4.11.7 allows local users to cause a denial of     service (over-boundary access) or possibly have     unspecified other impact by changing the value of a     message queue head pointer between two kernel reads of     that value, aka a 'double fetch'     vulnerability.(CVE-2017-9984i1/4%0

  - An integer overflow was discovered in the     qla2x00_sysfs_write_optrom_ctl function in     drivers/scsi/qla2xxx/qla_attr.c in the Linux kernel     through 4.12.10. This flaw allows local users to cause     a denial of service (memory corruption and system     crash) by leveraging root access.(CVE-2017-14051i1/4%0

  - A use-after-free 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-2014-4654i1/4%0

  - An information leak flaw was found in the way the Linux     kernel's Virtual Dynamic Shared Object (vDSO)     implementation performed address randomization. A     local, unprivileged user could use this flaw to leak     kernel memory addresses to user-space.(CVE-2014-9585i1/4%0

  - The usbhid_parse function in     drivers/hid/usbhid/hid-core.c in the Linux kernel,     before 4.13.8, allows local users to cause a denial of     service (out-of-bounds read and system crash) or     possibly have unspecified other impact via a crafted     USB device.(CVE-2017-16533i1/4%0

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

CVE-2016-10208

Sergej Schumilo and Ralf Spenneberg discovered that a crafted ext4 filesystem could trigger memory corruption when it is mounted. A user that can provide a device or filesystem image to be mounted could use this for denial of service (crash or data corruption) or possibly for privilege escalation.

CVE-2017-8824

Mohamed Ghannam discovered that the DCCP implementation did not correctly manage resources when a socket is disconnected and reconnected, potentially leading to a use-after-free. A local user could use this for denial of service (crash or data corruption) or possibly for privilege escalation. On systems that do not already have the dccp module loaded, this can be mitigated by disabling it: echo >> /etc/modprobe.d/disable-dccp.conf install dccp false

CVE-2017-8831

Pengfei Wang discovered that the saa7164 video capture driver re-reads data from a PCI device after validating it. A physically present user able to attach a specially designed PCI device could use this for privilege escalation.

CVE-2017-12190

Vitaly Mayatskikh discovered that the block layer did not correctly count page references for raw I/O from user-space. This can be exploited by a guest VM with access to a host SCSI device for denial of service (memory exhaustion) or potentially for privilege escalation.

CVE-2017-13080

A vulnerability was found in the WPA2 protocol that could lead to reinstallation of the same Group Temporal Key (GTK), which substantially reduces the security of wifi encryption. This is one of the issues collectively known as 'KRACK'.

Updates to GTKs are usually handled by the wpa package, where this issue was already fixed (DLA-1150-1). However, some wifi devices can remain active and update GTKs autonomously while the system is suspended. The kernel must also check for and ignore key reinstallation.

CVE-2017-14051

(CVE-2017-18017)    - In the Linux kernel 4.12, 3.10, 2.6 and possibly earlier versions a race condition vulnerability exists in     the sound system, this can lead to a deadlock and denial of service condition. (CVE-2018-1000004)    - The Salsa20 encryption algorithm in the Linux kernel before 4.14.8 does not correctly handle zero-length     inputs, allowing a local attacker able to use the AF_ALG-based skcipher interface     (CONFIG_CRYPTO_USER_API_SKCIPHER) to cause a denial of service (uninitialized-memory free and kernel     crash) or have 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 were vulnerable. (CVE-2017-17805)    - The ext4_iget function in fs/ext4/inode.c in the Linux kernel through 4.15.15 mishandles the case of a     root directory with a zero i_links_count, which allows attackers to cause a denial of service     (ext4_process_freed_data NULL pointer dereference and OOPS) via a crafted ext4 image. (CVE-2018-1092)    - In the function wmi_set_ie(), the length validation code does not handle unsigned integer overflow     properly. As a result, a large value of the 'ie_len' argument can cause a buffer overflow in all Android     releases from CAF (Android for MSM, Firefox OS for MSM, QRD Android) using the Linux Kernel.     (CVE-2018-5848)    - Memory leak in the sas_smp_get_phy_events function in drivers/scsi/libsas/sas_expander.c in the Linux     kernel through 4.15.7 allows local users to cause a denial of service (memory consumption) via many read     accesses to files in the /sys/class/sas_phy directory, as demonstrated by the     /sys/class/sas_phy/phy-1:0:12/invalid_dword_count file. (CVE-2018-7757)    - It was found that the raw midi kernel driver does not protect against concurrent access which leads to a     double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status() which are part     of snd_rawmidi_ioctl() handler in rawmidi.c file. A malicious local attacker could possibly use this for     privilege escalation. (CVE-2018-10902)    - An elevation of privilege vulnerability in the kernel scsi driver. Product: Android. Versions: Android     kernel.
Android ID A-65023233. (CVE-2017-13168)    - ** DISPUTED ** Linux Kernel version 3.18 to 4.16 incorrectly handles an SG_IO ioctl on /dev/sg0 with     dxfer_direction=SG_DXFER_FROM_DEV and an empty 6-byte cmdp. This may lead to copying up to 1000 kernel     heap pages to the userspace. This has been fixed upstream in     http://www.nessus.org/u?5d4e77b1 already. The problem has     limited scope, as users don't usually have permissions to access SCSI devices. On the other hand, e.g. the     Nero user manual suggests doing `chmod o+r+w /dev/sg*` to make the devices accessible. NOTE: third parties     dispute the relevance of this report, noting that the requirement for an attacker to have both the CAP_SYS_ADMIN and CAP_SYS_RAWIO capabilities makes it virtually impossible to exploit.     (CVE-2018-1000204)    - An issue was discovered in the Linux kernel through 4.19. An information leak in cdrom_ioctl_select_disc     in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from     unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 and     CVE-2018-16658. (CVE-2018-18710)    - The UDF filesystem implementation in the Linux kernel before 3.18.2 does not validate certain lengths,     which allows local users to cause a denial of service (buffer over-read and system crash) via a crafted     filesystem image, related to fs/udf/inode.c and fs/udf/symlink.c. (CVE-2014-9728)    - 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-2016-3713)    - The HMAC implementation (crypto/hmac.c) in the Linux kernel before 4.14.8 does not validate that the     underlying cryptographic hash algorithm is unkeyed, allowing a local attacker able to use the AF_ALG-based     hash interface (CONFIG_CRYPTO_USER_API_HASH) and the SHA-3 hash algorithm (CONFIG_CRYPTO_SHA3) to cause a     kernel stack buffer overflow by executing a crafted sequence of system calls that encounter a missing     SHA-3 initialization. (CVE-2017-17806)    - An issue was discovered in the fd_locked_ioctl function in drivers/block/floppy.c in the Linux kernel     through 4.15.7. The floppy driver will copy a kernel pointer to user memory in response to the FDGETPRM     ioctl. An attacker can send the FDGETPRM ioctl and use the obtained kernel pointer to discover the location of kernel code and data and bypass kernel security protections such as KASLR. (CVE-2018-7755)    - ** DISPUTED
** drivers/scsi/libsas/sas_scsi_host.c in the Linux kernel before 4.16 allows local users to     cause a denial of service (ata qc leak) by triggering certain failure conditions. NOTE: a third party     disputes the relevance of this report because the failure can only occur for physically proximate     attackers who unplug SAS Host Bus Adapter cables.
(CVE-2018-10021)    - drivers/input/serio/i8042.c in the Linux kernel before 4.12.4 allows attackers to cause a denial of     service (NULL pointer dereference and system crash) or possibly have unspecified other impact because the port->exists value can change after it is validated. (CVE-2017-18079)    - An integer overflow in the qla2x00_sysfs_write_optrom_ctl function in drivers/scsi/qla2xxx/qla_attr.c in     the Linux kernel through 4.12.10 allows local users to cause a denial of service (memory corruption and     system crash) by leveraging root access.
(CVE-2017-14051)    - net/netfilter/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, which allows local users to bypass intended access restrictions because the xt_osf_fingers data structure is shared across all net namespaces.     (CVE-2017-17450)    - ** DISPUTED ** Race condition in the store_int_with_restart() function in arch/x86/kernel/cpu/mcheck/mce.c     in the Linux kernel through 4.15.7 allows local users to cause a denial of service (panic) by leveraging     root access to write to the check_interval file in a /sys/devices/system/machinecheck/machinecheck directory. NOTE: a third party has indicated that this report is not security relevant.     (CVE-2018-7995)    - In hid_debug_events_read of drivers/hid/hid-debug.c, there is a possible out of bounds write due to a     missing bounds check. This could lead to local escalation of privilege with System execution privileges     needed. User interaction is not needed for exploitation. Product: Android Versions: Android kernel Android     ID: A-71361580. (CVE-2018-9516)  Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
