According to the versions of the kernel packages installed, the EulerOS 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):In the Linux kernel     4.19.83, there is a use-after-free (read) in the     debugfs_remove function in fs/debugfs/inode.c (which is     used to remove a file or directory in debugfs that was     previously created with a call to another debugfs     function such as     debugfs_create_file).(CVE-2019-19770)mwifiex_tm_cmd in     driverset/wireless/marvell/mwifiex/cfg80211.c in the     Linux kernel before 5.1.6 has some error-handling cases     that did not free allocated hostcmd memory, aka     CID-003b686ace82. This will cause a memory leak and     denial of service.(CVE-2019-20095)TSX Asynchronous     Abort condition on some CPUs utilizing speculative     execution may allow an authenticated user to     potentially enable information disclosure via a side     channel with local access.(CVE-2019-11135)A memory leak     in the crypto_report() function in     crypto/crypto_user_base.c in the Linux kernel through     5.3.11 allows attackers to cause a denial of service     (memory consumption) by triggering crypto_report_alg()     failures, aka CID-ffdde5932042.(CVE-2019-19062)In the     Linux kernel before 5.1.6, there is a use-after-free in     serial_ir_init_module() in     drivers/media/rc/serial_ir.c.(CVE-2019-19543)In the     Linux kernel through 5.4.6, there is a NULL pointer     dereference in drivers/scsi/libsas/sas_discover.c     because of mishandling of port disconnection during     discovery, related to a PHY down race condition, aka     CID-f70267f379b5.(CVE-2019-19965)In the Linux kernel     before 5.1.6, there is a use-after-free in cpia2_exit()     in drivers/media/usb/cpia2/cpia2_v4l.c that will cause     denial of service, aka     CID-dea37a972655.(CVE-2019-19966)An issue was     discovered in drivers/xen/balloon.c in the Linux kernel     before 5.2.3, as used in Xen through 4.12.x, allowing     guest OS users to cause a denial of service because of     unrestricted resource consumption during the mapping of     guest memory, aka CID-6ef36ab967c7.(CVE-2019-17351)A     memory leak in the crypto_reportstat() function in     drivers/virt/vboxguest/vboxguest_utils.c in the Linux     kernel before 5.3.9 allows attackers to cause a denial     of service (memory consumption) by triggering     copy_form_user() failures, aka     CID-e0b0cb938864.(CVE-2019-19048)kernel/sched/fair.c in     the Linux kernel before 5.3.9, when cpu.cfs_quota_us is     used (e.g., with Kubernetes), allows attackers to cause     a denial of service against non-cpu-bound applications     by generating a workload that triggers unwanted slice     expiration, aka CID-de53fd7aedb1. (In other words,     although this slice expiration would typically be seen     with benign workloads, it is possible that an attacker     could calculate how many stray requests are required to     force an entire Kubernetes cluster into a     low-performance state caused by slice expiration, and     ensure that a DDoS attack sent that number of stray     requests. An attack does not affect the stability of     the kernel it only causes mismanagement of application     execution.)(CVE-2019-19922)An out-of-bounds memory     write issue was found in the Linux Kernel, version 3.13     through 5.4, in the way the Linux kernel's KVM     hypervisor handled the 'KVM_GET_EMULATED_CPUID'     ioctl(2) request to get CPUID features emulated by the     KVM hypervisor. A user or process able to access the     '/dev/kvm' device could use this flaw to crash the     system, resulting in a denial of     service.(CVE-2019-19332)A flaw was found in the fix for     CVE-2019-11135, the way Intel CPUs handle speculative     execution of instructions when a TSX Asynchronous Abort     (TAA) error occurs. When a guest is running on a host     CPU affected by the TAA flaw (TAA_NO=0), but is not     affected by the MDS issue (MDS_NO=1), the guest was to     clear the affected buffers by using a VERW instruction     mechanism. But when the MDS_NO=1 bit was exported to     the guests, the guests did not use the VERW mechanism     to clear the affected buffers. This issue affects     guests running on Cascade Lake CPUs and requires that     host has 'TSX' enabled. Confidentiality of data is the     highest threat associated with this     vulnerability.(CVE-2019-19338)In the Linux kernel     5.0.0-rc7 (as distributed in ubuntu/linux.git on     kernel.ubuntu.com), mounting a crafted f2fs filesystem     image and performing some operations can lead to     slab-out-of-bounds read access in ttm_put_pages in     drivers/gpu/drm/ttm/ttm_page_alloc.c. This is related     to the vmwgfx or ttm module.(CVE-2019-19927)In the     Linux kernel 4.14 longterm through 4.14.165 and 4.19     longterm through 4.19.96 (and 5.x before 5.2), there is     a use-after-free (write) in the i915_ppgtt_close     function in drivers/gpu/drm/i915/i915_gem_gtt.c, aka     CID-7dc40713618c. This is related to     i915_gem_context_destroy_ioctl in     drivers/gpu/drm/i915/i915_gem_context.c.(CVE-2020-7053)     In the Linux kernel through 5.4.6, there are     information leaks of uninitialized memory to a USB     device in the     driverset/can/usb/kvaser_usb/kvaser_usb_leaf.c driver,     aka CID-da2311a6385c.(CVE-2019-19947)In the Linux     kernel before 5.0.6, there is a NULL pointer     dereference in drop_sysctl_table() in     fs/proc/proc_sysctl.c, related to put_links, aka     CID-23da9588037e.(CVE-2019-20054)In the Linux kernel     before 5.1, there is a memory leak in
    __feat_register_sp() in net/dccp/feat.c, which may     cause denial of service, aka     CID-1d3ff0950e2b.(CVE-2019-20096)A heap-based buffer     overflow vulnerability was found in the Linux kernel,     version kernel-2.6.32, in Marvell WiFi chip driver. A     remote attacker could cause a denial of service (system     crash) or, possibly execute arbitrary code, when the     lbs_ibss_join_existing function is called after a STA     connects to an AP.(CVE-2019-14896)A heap-based buffer     overflow was discovered in the Linux kernel, all     versions 3.x.x and 4.x.x before 4.18.0, in Marvell WiFi     chip driver. The flaw could occur when the station     attempts a connection negotiation during the handling     of the remote devices country settings. This could     allow the remote device to cause a denial of service     (system crash) or possibly execute arbitrary     code.(CVE-2019-14895)A stack-based buffer overflow was     found in the Linux kernel, version kernel-2.6.32, in     Marvell WiFi chip driver. An attacker is able to cause     a denial of service (system crash) or, possibly execute     arbitrary code, when a STA works in IBSS mode (allows     connecting stations together without the use of an AP)     and connects to another STA.(CVE-2019-14897)An     exploitable denial-of-service vulnerability exists in     the Linux kernel prior to mainline 5.3. An attacker     could exploit this vulnerability by triggering AP to     send IAPP location updates for stations before the     required authentication process has completed. This     could lead to different denial-of-service scenarios,     either by causing CAM table attacks, or by leading to     traffic flapping if faking already existing clients in     other nearby APs of the same wireless infrastructure.
    An attacker can forge Authentication and Association     Request packets to trigger this     vulnerability.(CVE-2019-5108)drivers/gpu/drm/radeon/rad     eon_display.c in the Linux kernel 5.2.14 does not check     the alloc_workqueue return value, leading to a NULL     pointer dereference.(CVE-2019-16230)

The remote Ubuntu 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4226-1 advisory.

  - Linux kernel CIFS implementation, version 4.9.0 is vulnerable to a relative paths injection in directory     entry lists. (CVE-2019-10220)

  - A heap-based buffer overflow was discovered in the Linux kernel, all versions 3.x.x and 4.x.x before     4.18.0, in Marvell WiFi chip driver. The flaw could occur when the station attempts a connection     negotiation during the handling of the remote devices country settings. This could allow the remote device     to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-14895)

  - A heap-based buffer overflow vulnerability was found in the Linux kernel, version kernel-2.6.32, in     Marvell WiFi chip driver. A remote attacker could cause a denial of service (system crash) or, possibly     execute arbitrary code, when the lbs_ibss_join_existing function is called after a STA connects to an AP.
    (CVE-2019-14896)

  - A stack-based buffer overflow was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip     driver. An attacker is able to cause a denial of service (system crash) or, possibly execute arbitrary     code, when a STA works in IBSS mode (allows connecting stations together without the use of an AP) and     connects to another STA. (CVE-2019-14897)

  - A heap overflow flaw was found in the Linux kernel, all versions 3.x.x and 4.x.x before 4.18.0, in Marvell     WiFi chip driver. The vulnerability allows a remote attacker to cause a system crash, resulting in a     denial of service, or execute arbitrary code. The highest threat with this vulnerability is with the     availability of the system. If code execution occurs, the code will run with the permissions of root. This     will affect both confidentiality and integrity of files on the system. (CVE-2019-14901)

  - drivers/net/fjes/fjes_main.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value,     leading to a NULL pointer dereference. (CVE-2019-16231)

  - drivers/scsi/qla2xxx/qla_os.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value,     leading to a NULL pointer dereference. (CVE-2019-16233)

  - An issue was discovered in write_tpt_entry in drivers/infiniband/hw/cxgb4/mem.c in the Linux kernel     through 5.3.2. The cxgb4 driver is directly calling dma_map_single (a DMA function) from a stack variable.
    This could allow an attacker to trigger a Denial of Service, exploitable if this driver is used on an     architecture for which this stack/DMA interaction has security relevance. (CVE-2019-17075)

  - In the Linux kernel through 5.3.2, cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c does not reject a     long SSID IE, leading to a Buffer Overflow. (CVE-2019-17133)

  - The Linux kernel before 5.4.1 on powerpc allows Information Exposure because the Spectre-RSB mitigation is     not in place for all applicable CPUs, aka CID-39e72bf96f58. This is related to     arch/powerpc/kernel/entry_64.S and arch/powerpc/kernel/security.c. (CVE-2019-18660)

  - A memory leak in the dwc3_pci_probe() function in drivers/usb/dwc3/dwc3-pci.c in the Linux kernel through     5.3.9 allows attackers to cause a denial of service (memory consumption) by triggering     platform_device_add_properties() failures, aka CID-9bbfceea12a8. (CVE-2019-18813)

  - A memory leak in the mlx5_fpga_conn_create_cq() function in     drivers/net/ethernet/mellanox/mlx5/core/fpga/conn.c in the Linux kernel before 5.3.11 allows attackers to     cause a denial of service (memory consumption) by triggering mlx5_vector2eqn() failures, aka     CID-c8c2a057fdc7. (CVE-2019-19045)

  - A memory leak in the crypto_reportstat() function in drivers/virt/vboxguest/vboxguest_utils.c in the Linux     kernel before 5.3.9 allows attackers to cause a denial of service (memory consumption) by triggering     copy_form_user() failures, aka CID-e0b0cb938864. (CVE-2019-19048)

  - A memory leak in the gs_can_open() function in drivers/net/can/usb/gs_usb.c in the Linux kernel before     5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering usb_submit_urb()     failures, aka CID-fb5be6a7b486. (CVE-2019-19052)

  - A memory leak in the nl80211_get_ftm_responder_stats() function in net/wireless/nl80211.c in the Linux     kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering     nl80211hdr_put() failures, aka CID-1399c59fa929. NOTE: third parties dispute the relevance of this because     it occurs on a code path where a successful allocation has already occurred (CVE-2019-19055)

  - A memory leak in the adis_update_scan_mode() function in drivers/iio/imu/adis_buffer.c in the Linux kernel     before 5.3.9 allows attackers to cause a denial of service (memory consumption), aka CID-ab612b1daf41.
    (CVE-2019-19060)

  - A memory leak in the sdma_init() function in drivers/infiniband/hw/hfi1/sdma.c in the Linux kernel before     5.3.9 allows attackers to cause a denial of service (memory consumption) by triggering rhashtable_init()     failures, aka CID-34b3be18a04e. NOTE: This has been disputed as not a vulnerability because     rhashtable_init() can only fail if it is passed invalid values in the second parameter's struct, but when     invoked from sdma_init() that is a pointer to a static const struct, so an attacker could only trigger     failure if they could corrupt kernel memory (in which case a small memory leak is not a significant     problem). (CVE-2019-19065)

  - Four memory leaks in the acp_hw_init() function in drivers/gpu/drm/amd/amdgpu/amdgpu_acp.c in the Linux     kernel before 5.3.8 allow attackers to cause a denial of service (memory consumption) by triggering     mfd_add_hotplug_devices() or pm_genpd_add_device() failures, aka CID-57be09c6e874. NOTE: third parties     dispute the relevance of this because the attacker must already have privileges for module loading     (CVE-2019-19067)

  - A memory leak in the predicate_parse() function in kernel/trace/trace_events_filter.c in the Linux kernel     through 5.3.11 allows attackers to cause a denial of service (memory consumption), aka CID-96c5c6e6a5b6.

This affects the     dce112_clock_source_create() function in drivers/gpu/drm/amd/display/dc/dce112/dce112_resource.c, the     dce100_clock_source_create() function in drivers/gpu/drm/amd/display/dc/dce100/dce100_resource.c, the     dcn10_clock_source_create() function in drivers/gpu/drm/amd/display/dc/dcn10/dcn10_resource.c, the     dcn20_clock_source_create() function in drivers/gpu/drm/amd/display/dc/dcn20/dcn20_resource.c, the     dce120_clock_source_create() function in drivers/gpu/drm/amd/display/dc/dce120/dce120_resource.c, the     dce110_clock_source_create() function in drivers/gpu/drm/amd/display/dc/dce110/dce110_resource.c, and the     dce80_clock_source_create() function in drivers/gpu/drm/amd/display/dc/dce80/dce80_resource.c, aka     CID-055e547478a1. (CVE-2019-19083)

  - In the Linux kernel before 5.3.12, there is a use-after-free bug that can be caused by a malicious USB     device in the drivers/input/ff-memless.c driver, aka CID-fa3a5a1880c9. (CVE-2019-19524)

  - In the Linux kernel before 5.3.9, there is a use-after-free bug that can be caused by a malicious USB     device in the drivers/nfc/pn533/usb.c driver, aka CID-6af3aa57a098. (CVE-2019-19526)

  - In the Linux kernel before 5.3.11, there is a use-after-free bug that can be caused by a malicious USB     device in the drivers/net/can/usb/mcba_usb.c driver, aka CID-4d6636498c41. (CVE-2019-19529)

  - In the Linux kernel before 5.3.9, there are multiple out-of-bounds write bugs that can be caused by a     malicious USB device in the Linux kernel HID drivers, aka CID-d9d4b1e46d95. This affects drivers/hid/hid-     axff.c, drivers/hid/hid-dr.c, drivers/hid/hid-emsff.c, drivers/hid/hid-gaff.c, drivers/hid/hid-holtekff.c,     drivers/hid/hid-lg2ff.c, drivers/hid/hid-lg3ff.c, drivers/hid/hid-lg4ff.c, drivers/hid/hid-lgff.c,     drivers/hid/hid-logitech-hidpp.c, drivers/hid/hid-microsoft.c, drivers/hid/hid-sony.c, drivers/hid/hid-     tmff.c, and drivers/hid/hid-zpff.c. (CVE-2019-19532)

  - In the Linux kernel before 5.3.11, there is an info-leak bug that can be caused by a malicious USB device     in the drivers/net/can/usb/peak_usb/pcan_usb_core.c driver, aka CID-f7a1337f0d29. (CVE-2019-19534)

  - kernel/sched/fair.c in the Linux kernel before 5.3.9, when cpu.cfs_quota_us is used (e.g., with     Kubernetes), allows attackers to cause a denial of service against non-cpu-bound applications by     generating a workload that triggers unwanted slice expiration, aka CID-de53fd7aedb1. (In other words,     although this slice expiration would typically be seen with benign workloads, it is possible that an     attacker could calculate how many stray requests are required to force an entire Kubernetes cluster into a     low-performance state caused by slice expiration, and ensure that a DDoS attack sent that number of stray     requests. An attack does not affect the stability of the kernel; it only causes mismanagement of     application execution.) (CVE-2019-19922)

  - In binder_transaction of binder.c, there is a possible out of bounds write due to a missing bounds check.
    This could lead to local escalation of privilege with no additional execution privileges needed. User     interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:

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

The remote Ubuntu 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4208-1 advisory.

  - Overlayfs in the Linux kernel and shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu     5.0 and 5.3 kernel series, both replace vma->vm_file in their mmap handlers. On error the original value     is not restored, and the reference is put for the file to which vm_file points. On upstream kernels this     is not an issue, as no callers dereference vm_file following after call_mmap() returns an error. However,     the aufs patchs change mmap_region() to replace the fput() using a local variable with vma_fput(), which     will fput() vm_file, leading to a refcount underflow. (CVE-2019-15794)
