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):The uas driver in the     Linux kernel before 4.13.6 allows local users to cause     a denial of service (out-of-bounds read and system     crash), or possibly have unspecified other impacts via     a crafted USB device, related to     drivers/usb/storage/uas-detect.h and     drivers/usb/storage/uas.c.(CVE-2017-16530)The     implementation of big key management in     security/keys/big_key.c in the Linux kernel before     4.8.7 mishandles unsuccessful crypto registration in     conjunction with successful key-type registration,     which allows local users to cause a denial of service     (NULL pointer dereference and panic) or possibly have     unspecified other impact via a crafted application that     uses the big_key data type.(CVE-2016-9313)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)Buffer overflow in the     exitcode_proc_write function in     arch/um/kernel/exitcode.c in the Linux kernel before     3.12 allows local users to cause a denial of service or     possibly have unspecified other impact by leveraging     root privileges for a write operation.(CVE-2013-4512)It     was found that unsharing a mount namespace could allow     a user to see data beneath their restricted     namespace.(CVE-2014-9717)A divide-by-zero flaw was     discovered in the Linux kernel built with KVM     virtualization support(CONFIG_KVM). The flaw occurs in     the KVM module's Programmable Interval Timer(PIT)     emulation, when PIT counters for channel 1 or 2 are set     to zero(0) and a privileged user inside the guest     attempts to read these counters. A privileged guest     user with access to PIT I/O ports could exploit this     issue to crash the host kernel (denial of     service).(CVE-2015-7513)The ims_pcu_parse_cdc_data     function in drivers/input/misc/ims-pcu.c in the Linux     kernel before 4.5.1 allows physically proximate     attackers to cause a denial of service (system crash)     via a USB device without both a master and a slave     interface.(CVE-2016-3689)Stack-based buffer overflow in     the brcmf_cfg80211_start_ap() function in     'driverset/wireless/broadcom/brcm80211/brcmfmac/cfg8021     1.c' in the Linux kernel before 4.7.5 allows local     users to cause a denial of service (system crash) or     possibly have unspecified other impact via a long SSID     Information Element in a command to a Netlink     socket.(CVE-2016-8658)drivers/hid/hid-sony.c in the     Human Interface Device (HID) subsystem in the Linux     kernel through 3.11, when CONFIG_HID_SONY is enabled,     allows physically proximate attackers to cause a denial     of service (heap-based out-of-bounds write) via a     crafted device.(CVE-2013-2890)An issue where a provided     address with access_ok() is not checked was discovered     in i915_gem_execbuffer2_ioctl in     drivers/gpu/drm/i915/i915_gem_execbuffer.c in the Linux     kernel through 4.19.13. A local attacker can craft a     malicious IOCTL function call to overwrite arbitrary     kernel memory, resulting in a Denial of Service or     privilege escalation.(CVE-2018-20669)It was found that     the permission checks performed by the Linux kernel     when a netlink message was received were not     sufficient. A local, unprivileged user could     potentially bypass these restrictions by passing a     netlink socket as stdout or stderr to a more privileged     process and altering the output of this     process.(CVE-2014-0181)An issue was discovered in the     XFS filesystem in fs/xfs/libxfs/xfs_attr_leaf.c in the     Linux kernel. A NULL pointer dereference may occur for     a corrupted xfs image after xfs_da_shrink_inode() is     called with a NULL bp. This can lead to a system crash     and a denial of service.(CVE-2018-13094)The     irda_setsockopt function in net/irda/af_irda.c in the     Linux kernel, through 4.16, allows local users to cause     a denial of service (due to a use-after-free of the     ias_object and a system crash) or possibly have     unspecified other impact by leveraging an AF_IRDA     socket.(CVE-2018-6555)The x86/fpu (Floating Point Unit)     subsystem in the Linux kernel, when a processor     supports the xsave feature but not the xsaves feature,     does not correctly handle attempts to set reserved bits     in the xstate header via the ptrace() or rt_sigreturn()     system call. This allows local users to read the FPU     registers of other processes on the system, related to     arch/x86/kernel/fpu/regset.c and     arch/x86/kernel/fpu/signal.c.(CVE-2017-15537)The     fst_get_iface function in driverset/wan/farsync.c in     the Linux kernel before 3.11.7 does not properly     initialize a certain data structure, which allows local     users to obtain sensitive information from kernel     memory by leveraging the CAP_NET_ADMIN capability for     an SIOCWANDEV ioctl call.(CVE-2014-1444)In the Linux     kernel, through 4.15.4, the floppy driver reveals the     addresses of kernel functions and global variables     using printk calls within the function show_floppy in     drivers/block/floppy.c. An attacker can read this     information from dmesg and use the addresses to find     the locations of kernel code and data and bypass kernel     security protections such as KASLR.(CVE-2018-7273)A     flaw in 'arch/arm64/kernel/sys.c' in the Linux kernel     allows local users to bypass the 'strict page     permissions' protection mechanism and modify the     system-call table and, consequently, gain privileges by     leveraging write access.(CVE-2015-8967)The Linux kernel     before 3.11 on ARM platforms, as used in Android before     2016-08-05 on Nexus 5 and 7 (2013) devices, does not     properly consider user-space access to the TPIDRURW     register, which allows local users to gain privileges     via a crafted application, aka Android internal bug     28749743 and Qualcomm internal bug     CR561044.(CVE-2014-9870)A NULL pointer dereference     security flaw was found in the Linux kernel in the     vcpu_scan_ioapic() function in arch/x86/kvm/x86.c. This     allows local users with certain privileges to cause a     denial of service via a crafted system call to the KVM     subsystem.(CVE-2018-19407)It was found that current     implementation of kl5kusb105 driver failed to detect     short transfers when attempting to read the line state     and logged the content of the uninitialized heap     transfer buffer.(CVE-2017-5549)
