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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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

  - CVE-2016-6786 / CVE-2016-6787     It was discovered that the performance events subsystem     does not properly manage locks during certain     migrations, allowing a local attacker to escalate     privileges. This can be mitigated by disabling     unprivileged use of performance events:sysctl     kernel.perf_event_paranoid=3

  - CVE-2016-8405     Peter Pi of Trend Micro discovered that the frame buffer     video subsystem does not properly check bounds while     copying color maps to userspace, causing a heap buffer     out-of-bounds read, leading to information disclosure.

  - CVE-2016-9191     CAI Qian discovered that reference counting is not     properly handled within proc_sys_readdir in the sysctl     implementation, allowing a local denial of service     (system hang) or possibly privilege escalation.

  - CVE-2017-2583     Xiaohan Zhang reported that KVM for amd64 does not     correctly emulate loading of a null stack selector. This     can be used by a user in a guest VM for denial of     service (on an Intel CPU) or to escalate privileges     within the VM (on an AMD CPU).

  - CVE-2017-2584     Dmitry Vyukov reported that KVM for x86 does not     correctly emulate memory access by the SGDT and SIDT     instructions, which can result in a use-after-free and     information leak.

  - CVE-2017-2596     Dmitry Vyukov reported that KVM leaks page references     when emulating a VMON for a nested hypervisor. This can     be used by a privileged user in a guest VM for denial of     service or possibly to gain privileges in the host.

  - CVE-2017-2618     It was discovered that an off-by-one in the handling of     SELinux attributes in /proc/pid/attr could result in     local denial of service.

  - CVE-2017-5549     It was discovered that the KLSI KL5KUSB105 serial USB     device driver could log the contents of uninitialised     kernel memory, resulting in an information leak.

  - CVE-2017-5551     Jan Kara found that changing the POSIX ACL of a file on     tmpfs never cleared its set-group-ID flag, which should     be done if the user changing it is not a member of the     group-owner. In some cases, this would allow the     user-owner of an executable to gain the privileges of     the group-owner.

  - CVE-2017-5897     Andrey Konovalov discovered an out-of-bounds read flaw     in the ip6gre_err function in the IPv6 networking code.

  - CVE-2017-5970     Andrey Konovalov discovered a denial-of-service flaw in     the IPv4 networking code. This can be triggered by a     local or remote attacker if a local UDP or raw socket     has the IP_RETOPTS option enabled.

  - CVE-2017-6001     Di Shen discovered a race condition between concurrent     calls to the performance events subsystem, allowing a     local attacker to escalate privileges. This flaw exists     because of an incomplete fix of CVE-2016-6786. This can     be mitigated by disabling unprivileged use of     performance events: sysctl kernel.perf_event_paranoid=3

  - CVE-2017-6074     Andrey Konovalov discovered a use-after-free     vulnerability in the DCCP networking code, which could     result in denial of service or local 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

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

  - In do_epoll_ctl and ep_loop_check_proc of eventpoll.c,     there is a possible use after free due to a logic     error. This could lead to local escalation of privilege     with no additional execution privileges needed. User     interaction is not needed for     exploitation.(CVE-2020-0466)

  - fs/nfsd/nfs3xdr.c in the Linux kernel through 5.10.8,     when there is an NFS export of a subdirectory of a     filesystem, allows remote attackers to traverse to     other parts of the filesystem via READDIRPLUS. NOTE:
    some parties argue that such a subdirectory export is     not intended to prevent this attack see also the     exports(5) no_subtree_check default     behavior.(CVE-2021-3178)

  - An issue was discovered in the Linux kernel through     5.11.3. A kernel pointer leak can be used to determine     the address of the iscsi_transport structure. When an     iSCSI transport is registered with the iSCSI subsystem,     the transport's handle is available to unprivileged     users via the sysfs file system, at     /sys/class/iscsi_transport/$TRANSPORT_NAME/handle. When     read, the show_transport_handle function (in     drivers/scsi/scsi_transport_iscsi.c) is called, which     leaks the handle. This handle is actually the pointer     to an iscsi_transport struct in the kernel module's     global variables.(CVE-2021-27363)

  - An issue was discovered in the Linux kernel through     5.11.3. drivers/scsi/scsi_transport_iscsi.c is     adversely affected by the ability of an unprivileged     user to craft Netlink messages.(CVE-2021-27364)

  - A race condition was found in the Linux kernels     implementation of the floppy disk drive controller     driver software. The impact of this issue is lessened     by the fact that the default permissions on the floppy     device (/dev/fd0) are restricted to root. If the     permissions on the device have changed the impact     changes greatly. In the default configuration root (or     equivalent) permissions are required to attack this     flaw.(CVE-2021-20261)

  - In fs/ocfs2/cluster/nodemanager.c in the Linux kernel     before 4.15, local users can cause a denial of service     (NULL pointer dereference and BUG) because a required     mutex is not used.(CVE-2017-18216)

  - The omninet_open function in     drivers/usb/serial/omninet.c in the Linux kernel before     4.10.4 allows local users to cause a denial of service     (tty exhaustion) by leveraging reference count     mishandling.(CVE-2017-8925)

  - A flaw was found in the way memory resources were freed     in the unix_stream_recvmsg function in the Linux kernel     when a signal was pending. This flaw allows an     unprivileged local user to crash the system by     exhausting available memory. The highest threat from     this vulnerability is to system     availability.(CVE-2021-20265)

  - A flaw was found in the JFS filesystem code in the     Linux Kernel which allows a local attacker with the     ability to set extended attributes to panic the system,     causing memory corruption or escalating privileges. The     highest threat from this vulnerability is to     confidentiality, integrity, as well as system     availability.(CVE-2020-27815)

  - An out-of-bounds (OOB) memory access flaw was found in     x25_bind in net/x25/af_x25.c in the Linux kernel     version v5.12-rc5. A bounds check failure allows a     local attacker with a user account on the system to     gain access to out-of-bounds memory, leading to a     system crash or a leak of internal kernel information.
    The highest threat from this vulnerability is to     confidentiality, integrity, as well as system     availability.(CVE-2020-35519)

  - There is a flaw reported in the Linux kernel in     versions before 5.9 in     drivers/gpu/drm/nouveau/nouveau_sgdma.c in     nouveau_sgdma_create_ttm in Nouveau DRM subsystem. The     issue results from the lack of validating the existence     of an object prior to performing operations on the     object. An attacker with a local account with a root     privilege, can leverage this vulnerability to escalate     privileges and execute code in the context of the     kernel.(CVE-2021-20292)

  - In drivers/pci/hotplug/rpadlpar_sysfs.c in the Linux     kernel through 5.11.8, the RPA PCI Hotplug driver has a     user-tolerable buffer overflow when writing a new     device name to the driver from userspace, allowing     userspace to write data to the kernel stack frame     directly. This occurs because add_slot_store and     remove_slot_store mishandle drc_name '\0' termination,     aka CID-cc7a0bb058b8.(CVE-2021-28972)

  - A race condition was discovered in get_old_root in     fs/btrfs/ctree.c in the Linux kernel through 5.11.8. It     allows attackers to cause a denial of service (BUG)     because of a lack of locking on an extent buffer before     a cloning operation, aka     CID-dbcc7d57bffc.(CVE-2021-28964)

  - An issue was discovered in the Linux kernel before     5.11.7. usbip_sockfd_store in     drivers/usb/usbip/stub_dev.c allows attackers to cause     a denial of service (GPF) because the stub-up sequence     has race conditions during an update of the local and     shared status, aka CID-9380afd6df70.(CVE-2021-29265)

  - BPF JIT compilers in the Linux kernel through 5.11.12     have incorrect computation of branch displacements,     allowing them to execute arbitrary code within the     kernel context. This affects     arch/x86/net/bpf_jit_comp.c and     arch/x86/net/bpf_jit_comp32.c.(CVE-2021-29154)

  - The KVM implementation in the Linux kernel through     4.14.7 allows attackers to obtain potentially sensitive     information from kernel memory, aka a write_mmio     stack-based out-of-bounds read, related to     arch/x86/kvm/x86.c and     include/trace/events/kvm.h.(CVE-2017-17741)

  - An issue was discovered in the Linux kernel before     5.11.3 when a webcam device exists. video_usercopy in     drivers/media/v4l2-core/v4l2-ioctl.c has a memory leak     for large arguments, aka     CID-fb18802a338b.(CVE-2021-30002)

  - An issue was discovered in the Linux kernel through     4.17.10. There is an invalid pointer dereference in
    __del_reloc_root() in fs/btrfs/relocation.c when     mounting a crafted btrfs image, related to removing     reloc rb_trees when reloc control has not been     initialized.(CVE-2018-14609)

  - An issue was discovered in     fs/xfs/libxfs/xfs_inode_buf.c in the Linux kernel     through 4.17.3. A denial of service (memory corruption     and BUG) can occur for a corrupted xfs image upon     encountering an inode that is in extent format, but has     more extents than fit in the inode     fork.(CVE-2018-13095)

  - The vmw_gb_surface_define_ioctl function in     drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux     kernel through 4.10.7 does not validate certain levels     data, which allows local users to cause a denial of     service (system hang) via a crafted ioctl call for a     /dev/dri/renderD* device.(CVE-2017-7346)

  - The klsi_105_get_line_state function in     drivers/usb/serial/kl5kusb105.c in the Linux kernel     before 4.9.5 places uninitialized heap-memory contents     into a log entry upon a failure to read the line     status, which allows local users to obtain sensitive     information by reading the log.(CVE-2017-5549)

  - An integer overflow in the uvesafb_setcmap function in     drivers/video/fbdev/uvesafb.c in the Linux kernel     before 4.17.4 could result in local attackers being     able to crash the kernel or potentially elevate     privileges because kmalloc_array is not     used.(CVE-2018-13406)

  - In the Linux kernel before version 4.12, Kerberos 5     tickets decoded when using the RXRPC keys incorrectly     assumes the size of a field. This could lead to the     size-remaining variable wrapping and the data pointer     going over the end of the buffer. This could possibly     lead to memory corruption and possible privilege     escalation.(CVE-2017-7482)

  - drivers/net/usb/rtl8150.c in the Linux kernel 4.9.x     before 4.9.11 interacts incorrectly with the     CONFIG_VMAP_STACK option, which allows local users to     cause a denial of service (system crash or memory     corruption) or possibly have unspecified other impact     by leveraging use of more than one virtual page for a     DMA scatterlist.(CVE-2017-8069)

  - An issue was discovered in the Linux kernel through     5.11.3. Certain iSCSI data structures do not have     appropriate length constraints or checks, and can     exceed the PAGE_SIZE value. An unprivileged user can     send a Netlink message that is associated with iSCSI,     and has a length up to the maximum length of a Netlink     message.(CVE-2021-27365)

  - A flaw was found in the Nosy driver in the Linux     kernel. This issue allows a device to be inserted twice     into a doubly-linked list, leading to a use-after-free     when one of these devices is removed. The highest     threat from this vulnerability is to confidentiality,     integrity, as well as system availability. Versions     before kernel 5.12-rc6 are affected(CVE-2021-3483)

  - An issue was discovered in the FUSE filesystem     implementation in the Linux kernel before 5.10.6, aka     CID-5d069dbe8aaf. fuse_do_getattr() calls     make_bad_inode() in inappropriate situations, causing a     system crash.

    Dmitry Vyukov discovered race conditions in the Infrared (IrDA) subsystem in the Linux kernel. A local     attacker could use this to cause a denial of service (deadlock). (CVE-2017-6348)

    Dmitry Vyukov discovered that the generic SCSI (sg) subsystem in the Linux kernel contained a stack-based     buffer overflow. A local attacker with access to an sg device could use this to cause a denial of service     (system crash) or possibly execute arbitrary code. (CVE-2017-7187)

    It was discovered that a NULL pointer dereference existed in the Direct Rendering Manager (DRM) driver for     VMWare devices in the Linux kernel. A local attacker could use this to cause a denial of service (system     crash). (CVE-2017-7261)

    It was discovered that the USB Cypress HID drivers for the Linux kernel did not properly validate reported     information from the device. An attacker with physical access could use this to expose sensitive     information (kernel memory). (CVE-2017-7273)

    Eric Biggers discovered a memory leak in the keyring implementation in the Linux kernel. A local attacker     could use this to cause a denial of service (memory consumption). (CVE-2017-7472)

    It was discovered that an information leak existed in the set_mempolicy and mbind compat syscalls in the     Linux kernel. A local attacker could use this to expose sensitive information (kernel memory).
    (CVE-2017-7616)

    Sabrina Dubroca discovered that the asynchronous cryptographic hash (ahash) implementation in the Linux     kernel did not properly handle a full request queue. A local attacker could use this to cause a denial of     service (infinite recursion). (CVE-2017-7618)

    Tuomas Haanp and Ari Kauppi discovered that the NFSv2 and NFSv3 server implementations in the Linux     kernel did not properly handle certain long RPC replies. A remote attacker could use this to cause a     denial of service (system crash). (CVE-2017-7645)

    Tommi Rantala and Brad Spengler discovered that the memory manager in the Linux kernel did not properly     enforce the CONFIG_STRICT_DEVMEM protection mechanism. A local attacker with access to /dev/mem could use     this to expose sensitive information or possibly execute arbitrary code. (CVE-2017-7889)

    Tuomas Haanp and Ari Kauppi discovered that the NFSv2 and NFSv3 server implementations in the Linux     kernel did not properly check for the end of buffer. A remote attacker could use this to craft requests     that cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-7895)

    It was discovered that an integer underflow existed in the Edgeport USB Serial Converter device driver of     the Linux kernel. An attacker with physical access could use this to expose sensitive information (kernel     memory). (CVE-2017-8924)

    It was discovered that the USB ZyXEL omni.net LCD PLUS driver in the Linux kernel did not properly perform     reference counting. A local attacker could use this to cause a denial of service (tty exhaustion).
    (CVE-2017-8925)

    Jann Horn discovered that bpf in Linux kernel does not restrict the output of the print_bpf_insn function.
    A local attacker could use this to obtain sensitive address information. (CVE-2017-9150)

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

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - kernel: netfilter: use-after-free in tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c     (CVE-2017-18017)

  - The ia64 subsystem in the Linux kernel before 2.6.26 allows local users to cause a denial of service     (stack consumption and system crash) via a crafted application that leverages the mishandling of invalid     Register Stack Engine (RSE) state. (CVE-2006-3635)

  - drivers/media/video/videobuf-vmalloc.c in the Linux kernel before 2.6.24 does not initialize     videobuf_mapping data structures, which allows local users to trigger an incorrect count value and     videobuf leak via unspecified vectors, a different vulnerability than CVE-2010-5321. (CVE-2007-6761)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

This plugin has been deprecated as it does not adhere to established standards for this style of check.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - kernel: Buffer overflow due to unbounded strcpy in ISDN I4L driver (CVE-2017-12762)

  - kernel: buffer-overflow hardening in WiFi beacon validation code. (CVE-2019-16746)

  - include/linux/init_task.h in the Linux kernel before 2.6.35 does not prevent signals with a process group     ID of zero from reaching the swapper process, which allows local users to cause a denial of service     (system crash) by leveraging access to this process group. (CVE-2010-5328)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.
