arch/x86/entry/entry_64.S in the Linux kernel before 4.1.6 on the x86_64 platform improperly relies on espfix64 during nested NMI processing, which allows local users to gain privileges by triggering an NMI within a certain instruction window.

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 :

  - Linux kernel built with the KVM visualization support     (CONFIG_KVM), with nested visualization(nVMX) feature     enabled(nested=1), is vulnerable to host memory leakage     issue. It could occur while emulating VMXON instruction     in 'handle_vmon'. An L1 guest user could use this flaw     to leak host memory potentially resulting in     DoS.(CVE-2017-2596i1/4%0

  - The (1) BPF_S_ANC_NLATTR and (2) BPF_S_ANC_NLATTR_NEST     extension implementations in the sk_run_filter function     in net/core/filter.c in the Linux kernel through 3.14.3     do not check whether a certain length value is     sufficiently large, which allows local users to cause a     denial of service (integer underflow and system crash)     via crafted BPF instructions. NOTE: the affected code     was moved to the __skb_get_nlattr and
    __skb_get_nlattr_nest functions before the     vulnerability was announced.(CVE-2014-3144i1/4%0

  - A flaw was found in the Linux kernel when freeing pages     in hugetlbfs. This could trigger a local denial of     service by crashing the kernel.(CVE-2017-15127i1/4%0

  - An issue was discovered in the Linux kernel before 4.8.
    Incorrect access checking in overlayfs mounts could be     used by local attackers to modify or truncate files in     the underlying filesystem.(CVE-2018-16597i1/4%0

  - Memory leak in the cuse_channel_release function in     fs/fuse/cuse.c in the Linux kernel before 4.4 allows     local users to cause a denial of service (memory     consumption) or possibly have unspecified other impact     by opening /dev/cuse many times.(CVE-2015-1339i1/4%0

  - A flaw was found in the way the Linux kernel's nested     NMI handler and espfix64 functionalities interacted     during NMI processing. A local, unprivileged user could     use this flaw to crash the system or, potentially,     escalate their privileges on the     system.(CVE-2015-3290i1/4%0

  - Multiple array index errors in     drivers/hid/hid-multitouch.c in the Human Interface     Device (HID) subsystem in the Linux kernel through     3.11, when CONFIG_HID_MULTITOUCH is enabled, allow     physically proximate attackers to cause a denial of     service (heap memory corruption, or NULL pointer     dereference and OOPS) via a crafted     device.(CVE-2013-2897i1/4%0

  - A flaw was found in the way the Linux kernel's futex     subsystem handled the requeuing of certain Priority     Inheritance (PI) futexes. A local, unprivileged user     could use this flaw to escalate their privileges on the     system.(CVE-2014-3153i1/4%0

  - The XFS subsystem in the Linux kernel 4.4 and later     allows local users to cause a denial of service     (fdatasync() failure and system hang) by using the vfs     syscall group in the 'trinity' program, as a result of     a page lock order bug in the XFS seek hole/data     implementation.(CVE-2016-8660i1/4%0

  - A flaw was found in the Linux kernel's key management     system where it was possible for an attacker to     escalate privileges or crash the machine. If a user key     gets negatively instantiated, an error code is cached     in the payload area. A negatively instantiated key may     be then be positively instantiated by updating it with     valid data. However, the -i1/4zupdate key type method     must be aware that the error code may be     there.(CVE-2015-8539i1/4%0

  - It was found that the Linux kernel KVM subsystem's     sysenter instruction emulation was not sufficient. An     unprivileged guest user could use this flaw to escalate     their privileges by tricking the hypervisor to emulate     a SYSENTER instruction in 16-bit mode, if the guest OS     did not initialize the SYSENTER model-specific     registers (MSRs). Note: Certified guest operating     systems for Red Hat Enterprise Linux with KVM do     initialize the SYSENTER MSRs and are thus not     vulnerable to this issue when running on a KVM     hypervisor.(CVE-2015-0239i1/4%0

  - An information leak flaw was found in the way the Linux     kernel handled media device enumerate entities IOCTL     requests. A local user able to access the /dev/media0     device file could use this flaw to leak kernel memory     bytes.(CVE-2014-1739i1/4%0

  - The dgnc_mgmt_ioctl function in     drivers/staging/dgnc/dgnc_mgmt.c in the Linux kernel     through 4.3.3 does not initialize a certain structure     member, which allows local users to obtain sensitive     information from kernel memory via a crafted     application.(CVE-2015-7885i1/4%0

  - An information leak was discovered in the Linux kernel     in cdrom_ioctl_drive_status() function in     drivers/cdrom/cdrom.c that could be used by local     attackers to read kernel memory at certain     location.(CVE-2018-16658i1/4%0

  - A flaw was discovered in the Linux kernel's     implementation of VFIO. An attacker issuing an ioctl     can create a situation where memory is corrupted and     modify memory outside of the expected area. This may     overwrite kernel memory and subvert kernel     execution.(CVE-2016-9083i1/4%0

  - It was found that the Linux kernel's KVM subsystem did     not handle the VM exits gracefully for the invvpid     (Invalidate Translations Based on VPID) instructions.
    On hosts with an Intel processor and invppid VM exit     support, an unprivileged guest user could use these     instructions to crash the guest.(CVE-2014-3646i1/4%0

  - An attacker on a network could abuse a flaw in the IPv6     stack fragment reassembly code to induce kernel memory     corruption on the system, possibly leading to a system     crash.(CVE-2016-9755i1/4%0

  - It was found that a regular user could remove xattr     permissions on files by using the chown or write system     calls. A local attacker could use this flaw to deny     elevated permissions from valid users, services, or     applications, potentially resulting in a denial of     service.(CVE-2015-1350i1/4%0

  - arch/powerpc/kvm/book3s_hv_rmhandlers.S in the Linux     kernel through 4.7 on PowerPC platforms, when     CONFIG_KVM_BOOK3S_64_HV is enabled, allows guest OS     users to cause a denial of service (host OS infinite     loop) by making a H_CEDE hypercall during the existence     of a suspended transaction.(CVE-2016-5412i1/4%0

  - An issue was discovered in the proc_pid_stack function     in fs/proc/base.c in the Linux kernel. An attacker with     a local account can trick the stack unwinder code to     leak stack contents to userspace. The fix allows only     root to inspect the kernel stack of an arbitrary     task.(CVE-2018-17972i1/4%0

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.

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

  - It was found that the Linux kernel's implementation of     vectored pipe read and write functionality did not take     into account the I/O vectors that were already     processed when retrying after a failed atomic access     operation, potentially resulting in memory corruption     due to an I/O vector array overrun. A local,     unprivileged user could use this flaw to crash the     system or, potentially, escalate their privileges on     the system.(CVE-2015-1805)

  - net/llc/sysctl_net_llc.c in the Linux kernel before     3.19 uses an incorrect data type in a sysctl table,     which allows local users to obtain potentially     sensitive information from kernel memory or possibly     have unspecified other impact by accessing a sysctl     entry.(CVE-2015-2041)

  - net/rds/sysctl.c in the Linux kernel before 3.19 uses     an incorrect data type in a sysctl table, which allows     local users to obtain potentially sensitive information     from kernel memory or possibly have unspecified other     impact by accessing a sysctl entry.(CVE-2015-2042)

  - Xen 3.3.x through 4.5.x and the Linux kernel through     3.19.1 do not properly restrict access to PCI command     registers, which might allow local guest OS users to     cause a denial of service (non-maskable interrupt and     host crash) by disabling the (1) memory or (2) I/O     decoding for a PCI Express device and then accessing     the device, which triggers an Unsupported Request (UR)     response.(CVE-2015-2150)

  - A stack-based buffer overflow flaw was found in the     Linux kernel's early load microcode functionality. On a     system with UEFI Secure Boot enabled, a local,     privileged user could use this flaw to increase their     privileges to the kernel (ring0) level, bypassing     intended restrictions in place.(CVE-2015-2666)

  - The xsave/xrstor implementation in     arch/x86/include/asm/xsave.h in the Linux kernel before     3.19.2 creates certain .altinstr_replacement pointers     and consequently does not provide any protection     against instruction faulting, which allows local users     to cause a denial of service (panic) by triggering a     fault, as demonstrated by an unaligned memory operand     or a non-canonical address memory     operand.(CVE-2015-2672)

  - A flaw was found in the way the Linux kernel's 32-bit     emulation implementation handled forking or closing of     a task with an 'int80' entry. A local user could     potentially use this flaw to escalate their privileges     on the system.(CVE-2015-2830)

  - It was found that the Linux kernel's TCP/IP protocol     suite implementation for IPv6 allowed the Hop Limit     value to be set to a smaller value than the default     one. An attacker on a local network could use this flaw     to prevent systems on that network from sending or     receiving network packets.(CVE-2015-2922)

  - A flaw was found in the way the Linux kernel's file     system implementation handled rename operations in     which the source was inside and the destination was     outside of a bind mount. A privileged user inside a     container could use this flaw to escape the bind mount     and, potentially, escalate their privileges on the     system.(CVE-2015-2925)

  - A race condition flaw was found in the way the Linux     kernel's SCTP implementation handled Address     Configuration lists when performing Address     Configuration Change (ASCONF). A local attacker could     use this flaw to crash the system via a race condition     triggered by setting certain ASCONF options on a     socket.(CVE-2015-3212)

  - mm/memory.c in the Linux kernel before 4.1.4 mishandles     anonymous pages, which allows local users to gain     privileges or cause a denial of service (page tainting)     via a crafted application that triggers writing to page     zero.(CVE-2015-3288)

  - A flaw was found in the way the Linux kernel's nested     NMI handler and espfix64 functionalities interacted     during NMI processing. A local, unprivileged user could     use this flaw to crash the system or, potentially,     escalate their privileges on the system.(CVE-2015-3290)

  - It was found that if a Non-Maskable Interrupt (NMI)     occurred immediately after a SYSCALL call or before a     SYSRET call with the user RSP pointing to the NMI IST     stack, the kernel could skip that NMI.(CVE-2015-3291)

  - A buffer overflow flaw was found in the way the Linux     kernel's Intel AES-NI instructions optimized version of     the RFC4106 GCM mode decryption functionality handled     fragmented packets. A remote attacker could use this     flaw to crash, or potentially escalate their privileges     on, a system over a connection with an active AES-GCM     mode IPSec security association.(CVE-2015-3331)

  - A race condition flaw was found between the chown and     execve system calls. When changing the owner of a     setuid user binary to root, the race condition could     momentarily make the binary setuid root. A local,     unprivileged user could potentially use this flaw to     escalate their privileges on the system.(CVE-2015-3339)

  - It was found that the Linux kernel's ping socket     implementation did not properly handle socket unhashing     during spurious disconnects, which could lead to a     use-after-free flaw. On x86-64 architecture systems, a     local user able to create ping sockets could use this     flaw to crash the system. On non-x86-64 architecture     systems, a local user able to create ping sockets could     use this flaw to escalate their privileges on the     system.(CVE-2015-3636)

  - An inode data validation error was found in Linux     kernels built with UDF file system (CONFIG_UDF_FS)     support. An attacker able to mount a     corrupted/malicious UDF file system image could cause     the kernel to crash.(CVE-2015-4167)

  - A flaw was discovered in the way the Linux kernel's TTY     subsystem handled the tty shutdown phase. A local,     unprivileged user could use this flaw to cause denial     of service on the system by holding a reference to the     ldisc lock during tty shutdown, causing a     deadlock.(CVE-2015-4170)

  - A flaw was discovered in the kernel's collect_mounts     function. If the kernel's audit subsystem called     collect_mounts to audit an unmounted path, it could     panic the system. With this flaw, an unprivileged user     could call umount(MNT_DETACH) to launch a     denial-of-service attack.(CVE-2015-4177)

  - A DoS flaw was found for a Linux kernel built for the     x86 architecture which had the KVM virtualization     support(CONFIG_KVM) enabled. The kernel would be     vulnerable to a NULL pointer dereference flaw in Linux     kernel's kvm_apic_has_events() function while doing an     ioctl. An unprivileged user able to access the     '/dev/kvm' device could use this flaw to crash the     system kernel.(CVE-2015-4692)

  - A flaw was found in the kernel's implementation of the     Berkeley Packet Filter (BPF). A local attacker could     craft BPF code to crash the system by creating a     situation in which the JIT compiler would fail to     correctly optimize the JIT image on the last pass. This     would lead to the CPU executing instructions that were     not part of the JIT code.(CVE-2015-4700)

  - A buffer overflow flaw was found in the way the Linux     kernel's virtio-net subsystem handled certain fraglists     when the GRO (Generic Receive Offload) functionality     was enabled in a bridged network configuration. An     attacker on the local network could potentially use     this flaw to crash the system, or, although unlikely,     elevate their privileges on the system.(CVE-2015-5156)

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

  - CVE-2015-3290     Andy Lutomirski discovered that the Linux kernel does     not properly handle nested NMIs. A local, unprivileged     user could use this flaw for privilege escalation.

  - CVE-2015-3291     Andy Lutomirski discovered that under certain conditions     a malicious userspace program can cause the kernel to     skip NMIs leading to a denial of service.

  - CVE-2015-4167     Carl Henrik Lunde discovered that the UDF implementation     is missing a necessary length check. A local user that     can mount devices could use this flaw to crash the     system.

  - CVE-2015-5157     Petr Matousek and Andy Lutomirski discovered that an NMI     that interrupts userspace and encounters an IRET fault     is incorrectly handled. A local, unprivileged user could     use this flaw for denial of service or possibly for     privilege escalation.

  - CVE-2015-5364     It was discovered that the Linux kernel does not     properly handle invalid UDP checksums. A remote attacker     could exploit this flaw to cause a denial of service     using a flood of UDP packets with invalid checksums.

  - CVE-2015-5366     It was discovered that the Linux kernel does not     properly handle invalid UDP checksums. A remote attacker     can cause a denial of service against applications that     use epoll by injecting a single packet with an invalid     checksum.
