Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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 was found in the     Linux kernel's NFS implementation, all versions 3.x and     all versions 4.x up to 4.20. An attacker, who is able     to mount an exported NFS filesystem, is able to trigger     a null pointer dereference by using an invalid NFS     sequence. This can panic the machine and deny access to     the NFS server. Any outstanding disk writes to the NFS     server will be lost.(CVE-2018-16871)An issue was     discovered in the Linux kernel before 4.18.7. In     create_qp_common in drivers/infiniband/hw/mlx5/qp.c,     mlx5_ib_create_qp_resp was never initialized, resulting     in a leak of stack memory to     userspace.(CVE-2018-20855)An issue was discovered in     the Linux kernel before 4.18.7. In block/blk-core.c,     there is an __blk_drain_queue() use-after-free because     a certain error case is mishandled.(CVE-2018-20856)The     Linux kernel 4.x (starting from 4.1) and 5.x before     5.0.8 allows Information Exposure (partial kernel     address disclosure), leading to a KASLR bypass.
    Specifically, it is possible to extract the KASLR     kernel image offset using the IP ID values the kernel     produces for connection-less protocols (e.g., UDP and     ICMP). When such traffic is sent to multiple     destination IP addresses, it is possible to obtain hash     collisions (of indices to the counter array) and     thereby obtain the hashing key (via enumeration). This     key contains enough bits from a kernel address (of a     static variable) so when the key is extracted (via     enumeration), the offset of the kernel image is     exposed. This attack can be carried out remotely, by     the attacker forcing the target device to send UDP or     ICMP (or certain other) traffic to attacker-controlled     IP addresses. Forcing a server to send UDP traffic is     trivial if the server is a DNS server. ICMP traffic is     trivial if the server answers ICMP Echo requests     (ping). For client targets, if the target visits the     attacker's web page, then WebRTC or gQUIC can be used     to force UDP traffic to attacker-controlled IP     addresses. NOTE: this attack against KASLR became     viable in 4.1 because IP ID generation was changed to     have a dependency on an address associated with a     network namespace.(CVE-2019-10639)** DISPUTED ** An     issue was discovered in ip6_ra_control in     net/ipv6/ipv6_sockglue.c in the Linux kernel through     5.1.5. There is an unchecked kmalloc of new_ra, which     might allow an attacker to cause a denial of service     (NULL pointer dereference and system crash). NOTE: This     has been disputed as not an     issue.(CVE-2019-12378)**DISPUTED** An issue was     discovered in the efi subsystem in the Linux kernel     through 5.1.5. phys_efi_set_virtual_address_map in     arch/x86/platform/efi/efi.c and efi_call_phys_prolog in     arch/x86/platform/efi/efi_64.c mishandle memory     allocation failures. NOTE: This id is disputed as not     being an issue because ?All the code touched by the     referenced commit runs only at boot, before any user     processes are started. Therefore, there is no     possibility for an unprivileged user to control     it.?.(CVE-2019-12380)** DISPUTED ** An issue was     discovered in ip_ra_control in net/ipv4/ip_sockglue.c     in the Linux kernel through 5.1.5. There is an     unchecked kmalloc of new_ra, which might allow an     attacker to cause a denial of service (NULL pointer     dereference and system crash). NOTE: this is disputed     because new_ra is never used if it is     NULL.(CVE-2019-12381)** DISPUTED ** An issue was     discovered in the MPT3COMMAND case in _ctl_ioctl_main     in drivers/scsi/mpt3sas/mpt3sas_ctl.c in the Linux     kernel through 5.1.5. It allows local users to cause a     denial of service or possibly have unspecified other     impact by changing the value of ioc_number between two     kernel reads of that value, aka a 'double fetch'     vulnerability. NOTE: a third party reports that this is     unexploitable because the doubly fetched value is not     used.(CVE-2019-12456)An issue was discovered in the     Linux kernel before 4.20.15. The nfc_llcp_build_tlv     function in netfc/llcp_commands.c may return NULL. If     the caller does not check for this, it will trigger a     NULL pointer dereference. This will cause denial of     service. This affects nfc_llcp_build_gb in     netfc/llcp_core.c.(CVE-2019-12818)An issue was     discovered in the Linux kernel before 5.0. The function
    __mdiobus_register() in driverset/phy/mdio_bus.c calls     put_device(), which will trigger a fixed_mdio_bus_init     use-after-free. This will cause a denial of     service.(CVE-2019-12819)A NULL pointer dereference     vulnerability in the function     nfc_genl_deactivate_target() in netfcetlink.c in the     Linux kernel before 5.1.13 can be triggered by a     malicious user-mode program that omits certain NFC     attributes, leading to denial of     service.(CVE-2019-12984)In the Linux kernel before     5.1.17, ptrace_link in kernel/ptrace.c mishandles the     recording of the credentials of a process that wants to     create a ptrace relationship, which allows local users     to obtain root access by leveraging certain scenarios     with a parent-child process relationship, where a     parent drops privileges and calls execve (potentially     allowing control by an attacker). One contributing     factor is an object lifetime issue (which can also     cause a panic). Another contributing factor is     incorrect marking of a ptrace relationship as     privileged, which is exploitable through (for example)     Polkit's pkexec helper with PTRACE_TRACEME. NOTE:
    SELinux deny_ptrace might be a usable workaround in     some environments.(CVE-2019-13272)In     parse_hid_report_descriptor in     drivers/input/tablet/gtco.c in the Linux kernel through     5.2.1, a malicious USB device can send an HID report     that triggers an out-of-bounds write during generation     of debugging messages.(CVE-2019-13631)In the Linux     kernel through 5.2.1 on the powerpc platform, when     hardware transactional memory is disabled, a local user     can cause a denial of service (TM Bad Thing exception     and system crash) via a sigreturn() system call that     sends a crafted signal frame. This affects     arch/powerpc/kernel/signal_32.c and     arch/powerpc/kernel/signal_64.c.(CVE-2019-13648)In the     Linux kernel before 5.2.3, set_geometry in     drivers/block/floppy.c does not validate the sect and     head fields, as demonstrated by an integer overflow and     out-of-bounds read. It can be triggered by an     unprivileged local user when a floppy disk has been     inserted. NOTE: QEMU creates the floppy device by     default.(CVE-2019-14283)In the Linux kernel before     5.2.3, drivers/block/floppy.c allows a denial of     service by setup_format_params division-by-zero. Two     consecutive ioctls can trigger the bug: the first one     should set the drive geometry with .sect and .rate     values that make F_SECT_PER_TRACK be zero. Next, the     floppy format operation should be called. It can be     triggered by an unprivileged local user even when a     floppy disk has not been inserted. NOTE: QEMU creates     the floppy device by default.(CVE-2019-14284)In the     Linux kernel before 4.16.4, a double-locking error in     drivers/usb/dwc3/gadget.c may potentially cause a     deadlock with f_hid.(CVE-2019-14763)An issue was     discovered in the Linux kernel before 5.2.6. There is a     use-after-free caused by a malicious USB device in the     drivers/media/v4l2-core/v4l2-dev.c driver because     drivers/media/radio/radio-raremono.c does not properly     allocate memory.(CVE-2019-15211)An issue was discovered     in the Linux kernel before 5.0.9. There is a     use-after-free in atalk_proc_exit, related to     net/appletalk/atalk_proc.c, net/appletalk/ddp.c, and     net/appletalk/sysctl_net_atalk.c.(CVE-2019-15292)A flaw     was found in the way the sit_init_net function in the     Linux kernel handled resource cleanup on errors. This     flaw allows an attacker to use the error conditions to     crash the system.(CVE-2019-16994)Note:
    kernel-4.19.36-vhulk1907.1.0.h529 and earlier versions     in EulerOS Virtualization for ARM 64 3.0.2.0 return     incorrect time information when executing the uname -a     command.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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

  - CVE-2018-20836     chenxiang reported a race condition in libsas, the     kernel subsystem supporting Serial Attached SCSI (SAS)     devices, which could lead to a use-after-free. It is not     clear how this might be exploited.

  - CVE-2019-1125     It was discovered that most x86 processors could     speculatively skip a conditional SWAPGS instruction used     when entering the kernel from user mode, and/or could     speculatively execute it when it should be skipped. This     is a subtype of Spectre variant 1, which could allow     local users to obtain sensitive information from the     kernel or other processes. It has been mitigated by     using memory barriers to limit speculative execution.
    Systems using an i386 kernel are not affected as the     kernel does not use SWAPGS.

  - CVE-2019-1999     A race condition was discovered in the Android binder     driver, which could lead to a use-after-free. If this     driver is loaded, a local user might be able to use this     for denial-of-service (memory corruption) or for     privilege escalation.

  - CVE-2019-10207     The syzkaller tool found a potential null dereference in     various drivers for UART-attached Bluetooth adapters. A     local user with access to a pty device or other suitable     tty device could use this for denial-of-service     (BUG/oops).

  - CVE-2019-10638     Amit Klein and Benny Pinkas discovered that the     generation of IP packet IDs used a weak hash function,     'jhash'. This could enable tracking individual computers     as they communicate with different remote servers and     from different networks. The 'siphash' function is now     used instead.

  - CVE-2019-12817     It was discovered that on the PowerPC (ppc64el)     architecture, the hash page table (HPT) code did not     correctly handle fork() in a process with memory mapped     at addresses above 512 TiB. This could lead to a     use-after-free in the kernel, or unintended sharing of     memory between user processes. A local user could use     this for privilege escalation. Systems using the radix     MMU, or a custom kernel with a 4 KiB page size, are not     affected.

  - CVE-2019-12984     It was discovered that the NFC protocol implementation     did not properly validate a netlink control message,     potentially leading to a NULL pointer dereference. A     local user on a system with an NFC interface could use     this for denial-of-service (BUG/oops).

  - CVE-2019-13233     Jann Horn discovered a race condition on the x86     architecture, in use of the LDT. This could lead to a     use-after-free. A local user could possibly use this for     denial-of-service.

  - CVE-2019-13631     It was discovered that the gtco driver for USB input     tablets could overrun a stack buffer with constant data     while parsing the device's descriptor. A physically     present user with a specially constructed USB device     could use this to cause a denial-of-service (BUG/oops),     or possibly for privilege escalation.

  - CVE-2019-13648     Praveen Pandey reported that on PowerPC (ppc64el)     systems without Transactional Memory (TM), the kernel     would still attempt to restore TM state passed to the     sigreturn() system call. A local user could use this for     denial-of-service (oops).

  - CVE-2019-14283     The syzkaller tool found a missing bounds check in the     floppy disk driver. A local user with access to a floppy     disk device, with a disk present, could use this to read     kernel memory beyond the I/O buffer, possibly obtaining     sensitive information.

  - CVE-2019-14284     The syzkaller tool found a potential division-by-zero in     the floppy disk driver. A local user with access to a     floppy disk device could use this for denial-of-service     (oops).
