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

  - A flaw was found in the Linux kernel's NFS41+     subsystem. NFS41+ shares mounted in different network     namespaces at the same time can make bc_svc_process()     use wrong back-channel IDs and cause a use-after-free     vulnerability. Thus a malicious container user can     cause a host kernel memory corruption and a system     panic. Due to the nature of the flaw, privilege     escalation cannot be fully ruled out.(CVE-2018-16884)

  - An elevation of privilege vulnerability in the kernel     scsi driver. Product: Android. Versions: Android     kernel. Android ID A-65023233.(CVE-2017-13168)

  - A flaw in the load_elf_binary() function in the Linux     kernel allows a local attacker to leak the base address     of .text and stack sections for setuid binaries and     bypass ASLR because install_exec_creds() is called too     late in this function.(CVE-2019-11190)

  - The SCTP socket buffer used by a userspace application     is not accounted by the cgroups subsystem. An attacker     can use this flaw to cause a denial of service     attack.(CVE-2019-3874)

  - A flaw was found in the Linux kernel ext4 filesystem.
    An out-of-bound access is possible in the     ext4_ext_drop_refs() function when operating on a     crafted ext4 filesystem image.(CVE-2018-10877)

  - Non-optimized code for key handling of shared futexes     was found in the Linux kernel in the form of unbounded     contention time due to the page lock for real-time     users. Before the fix, the page lock was an     unnecessarily heavy lock for the futex path that     protected too much. After the fix, the page lock is     only required in a specific corner case.(CVE-2018-9422)

  - A flaw was found in the Linux kernel in the     hid_debug_events_read() function in the     drivers/hid/hid-debug.c file. A lack of the certain     checks may allow a privileged user ('root') to achieve     an out-of-bounds write and thus receiving user space     buffer corruption.(CVE-2018-9516i1/4%0

  - A vulnerability was found in polkit. When     authentication is performed by a non-root user to     perform an administrative task, the authentication is     temporarily cached in such a way that a local attacker     could impersonate the authorized process, thus gaining     access to elevated privileges.(CVE-2019-6133)

  - A flaw was found in the implementation of the 'fill     buffer', a mechanism used by modern CPUs when a     cache-miss is made on L1 CPU cache. If an attacker can     generate a load operation that would create a page     fault, the execution will continue speculatively with     incorrect data from the fill buffer while the data is     fetched from higher level caches. This response time     can be measured to infer data in the fill buffer.
    (CVE-2018-12130)

  - Modern Intel microprocessors implement hardware-level     micro-optimizations to improve the performance of     writing data back to CPU caches. The write operation is     split into STA (STore Address) and STD (STore Data)     sub-operations. These sub-operations allow the     processor to hand-off address generation logic into     these sub-operations for optimized writes. Both of     these sub-operations write to a shared distributed     processor structure called the 'processor store     buffer'. As a result, an unprivileged attacker could     use this flaw to read private data resident within the     CPU's processor store buffer. (CVE-2018-12126)

  - Microprocessors use a aEUR~load portaEURtm subcomponent to     perform load operations from memory or IO. During a     load operation, the load port receives data from the     memory or IO subsystem and then provides the data to     the CPU registers and operations in the CPUaEURtms     pipelines. Stale load operations results are stored in     the 'load port' table until overwritten by newer     operations. Certain load-port operations triggered by     an attacker can be used to reveal data about previous     stale requests leaking data back to the attacker via a     timing side-channel. (CVE-2018-12127)

  - Uncacheable memory on some microprocessors utilizing     speculative execution may allow an authenticated user     to potentially enable information disclosure via a side     channel with local access. (CVE-2019-11091)

The remote Windows host is missing security update 4499167 or 4497398. It is, therefore, affected by multiple vulnerabilities :

  - A new subclass of speculative execution side channel vulnerabilities,     known as Microarchitectural Data Sampling, exist in Windows.
    An attacker who successfully exploited these vulnerabilities     may be able to read privileged data across trust boundaries.     In shared resource environments (such as exists in some cloud     services configurations), these vulnerabilities could allow     one virtual machine to improperly access information from     another. In non-browsing scenarios on standalone systems, an     attacker would need prior access to the system or an ability     to run a specially crafted application on the target system     to leverage these vulnerabilities.
    (CVE-2019-11091, CVE-2018-12126, CVE-2018-12127, CVE-2018-12130)

  - An elevation of privilege vulnerability exists in     Windows when the Win32k component fails to properly     handle objects in memory. An attacker who successfully     exploited this vulnerability could run arbitrary code in     kernel mode. An attacker could then install programs;

The update addresses the vulnerability by     correcting how .NET Framework and .NET Core applications     handle RegEx string processing. (CVE-2019-0820)

  - An elevation of privilege vulnerability exists in     Microsoft Windows when a man-in-the-middle attacker is     able to successfully decode and replace authentication     request using Kerberos, allowing an attacker to be     validated as an Administrator.

  - An elevation of privilege vulnerability exists in the     Unified Write Filter (UWF) feature for Windows 10 when     it improperly restricts access to the registry. An     attacker who successfully exploited the vulnerability     could make changes to the registry keys protected by UWF     without having administrator privileges.
    (CVE-2019-0942)

  - An information disclosure vulnerability exists when the     Windows GDI component improperly discloses the contents     of its memory. An attacker who successfully exploited     the vulnerability could obtain information to further     compromise the users system.

  - A security feature bypass vulnerability exists in     Windows Defender Application Control (WDAC) which could     allow an attacker to bypass WDAC enforcement. An     attacker who successfully exploited this vulnerability     could circumvent Windows PowerShell Constrained Language     Mode on the machine.  (CVE-2019-0733)

  - An elevation of privilege vulnerability exists in the     way Windows Error Reporting (WER) handles files. An     attacker who successfully exploited this vulnerability     could run arbitrary code in kernel mode.

  - A denial of service vulnerability exists when .NET     Framework or .NET Core improperly handle web requests.
    An attacker who successfully exploited this     vulnerability could cause a denial of service against a     .NET Framework or .NET Core web application. The     vulnerability can be exploited remotely, without     authentication. A remote unauthenticated attacker could     exploit this vulnerability by issuing specially crafted     requests to the .NET Framework or .NET Core application.
    The update addresses the vulnerability by correcting how     .NET Framework or .NET Core web applications handles web     requests. (CVE-2019-0980, CVE-2019-0981)

  - A remote code execution vulnerability exists when the     Windows Jet Database Engine improperly handles objects     in memory. An attacker who successfully exploited this     vulnerability could execute arbitrary code on a victim     system. An attacker could exploit this vulnerability by     enticing a victim to open a specially crafted file. The     update addresses the vulnerability by correcting the way     the Windows Jet Database Engine handles objects in     memory. (CVE-2019-0889, CVE-2019-0890, CVE-2019-0891,     CVE-2019-0893, CVE-2019-0894, CVE-2019-0895,     CVE-2019-0896, CVE-2019-0897, CVE-2019-0898,     CVE-2019-0899, CVE-2019-0900, CVE-2019-0901,     CVE-2019-0902)
