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 named FragmentSmack     was found in the way the Linux kernel handled     reassembly of fragmented IPv4 and IPv6 packets. A     remote attacker could use this flaw to trigger time and     calculation expensive fragment reassembly algorithm by     sending specially crafted packets which could lead to a     CPU saturation and hence a denial of service on the     system.(CVE-2018-5391)Multiple out-of-bounds write     flaws were found in the way the Cherry Cymotion     keyboard driver, KYE/Genius device drivers, Logitech     device drivers, Monterey Genius KB29E keyboard driver,     Petalynx Maxter remote control driver, and Sunplus     wireless desktop driver handled HID reports with an     invalid report descriptor size. An attacker with     physical access to the system could use either of these     flaws to write data past an allocated memory     buffer.(CVE-2014-3184)The __get_data_block function in     fs/f2fs/data.c in the Linux kernel before 4.11 allows     local users to cause a denial of service (integer     overflow and loop) via crafted use of the open and     fallocate system calls with an FS_IOC_FIEMAP     ioctl.(CVE-2017-18257)netetfilter/xt_osf.c in the Linux     kernel through 4.14.4 does not require the     CAP_NET_ADMIN capability for add_callback and     remove_callback operations. This allows local users to     bypass intended access restrictions because the     xt_osf_fingers data structure is shared across all     network namespaces.(CVE-2017-17450)A denial of service     flaw was discovered in the Linux kernel, where a race     condition caused a NULL pointer dereference in the RDS     socket-creation code. A local attacker could use this     flaw to create a situation in which a NULL pointer     crashed the kernel.(CVE-2015-7990)An issue was     discovered in the Linux kernel before 4.19.9. The USB     subsystem mishandles size checks during the reading of     an extra descriptor, related to
    __usb_get_extra_descriptor in     drivers/usb/core/usb.c.(CVE-2018-20169)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)The ovl_setattr function in     fs/overlayfs/inode.c in the Linux kernel through 4.3.3     attempts to merge distinct setattr operations, which     allows local users to bypass intended access     restrictions and modify the attributes of arbitrary     overlay files via a crafted     application.(CVE-2015-8660)A flaw was found in the     Linux kernel where a local user with a shell account     can abuse the userfaultfd syscall when using hugetlbfs.
    A missing size check in hugetlb_mcopy_atomic_pte could     create an invalid inode variable, leading to a kernel     panic.(CVE-2017-15128)An integer overflow flaw was     found in the way the lzo1x_decompress_safe() function     of the Linux kernel's LZO implementation processed     Literal Runs. A local attacker could, in extremely rare     cases, use this flaw to crash the system or,     potentially, escalate their privileges on the     system.(CVE-2014-4608)It was found that Linux kernel's     ptrace subsystem did not properly sanitize the     address-space-control bits when the program-status word     (PSW) was being set. On IBM S/390 systems, a local,     unprivileged user could use this flaw to set     address-space-control bits to the kernel space, and     thus gain read and write access to kernel     memory.(CVE-2014-3534)A use-after-free flaw was found     in the Linux kernel's file system encryption     implementation. A local user could revoke keyring keys     being used for ext4, f2fs, or ubifs encryption, causing     a denial of service on the system.(CVE-2017-7374)The     usbip_recv_xbuff function in     drivers/usb/usbip/usbip_common.c in the Linux kernel     before 4.5.3 allows remote attackers to cause a denial     of service (out-of-bounds write) or possibly have     unspecified other impact via a crafted length value in     a USB/IP packet.(CVE-2016-3955)A flaw was found in the     patches used to fix the 'dirtycow' vulnerability     (CVE-2016-5195). An attacker, able to run local code,     can exploit a race condition in transparent huge pages     to modify usually read-only huge     pages.(CVE-2017-1000405)The aio_mount function in     fs/aio.c in the Linux kernel does not properly restrict     execute access, which makes it easier for local users     to bypass intended SELinux W^X policy     restrictions.(CVE-2016-10044)The Serial Attached SCSI     (SAS) implementation in the Linux kernel mishandles a     mutex within libsas. This allows local users to cause a     denial of service (deadlock) by triggering certain     error-handling code.(CVE-2017-18232)A use-after-free     vulnerability was found in tcp_xmit_retransmit_queue     and other tcp_* functions. This condition could allow     an attacker to send an incorrect selective     acknowledgment to existing connections, possibly     resetting a connection.(CVE-2016-6828)The instruction     decoder in arch/x86/kvm/emulate.c in the KVM subsystem     in the Linux kernel before 3.18-rc2 does not properly     handle invalid instructions, which allows guest OS     users to cause a denial of service (NULL pointer     dereference and host OS crash) via a crafted     application that triggers (1) an improperly fetched     instruction or (2) an instruction that occupies too     many bytes. NOTE: this vulnerability exists because of     an incomplete fix for CVE-2014-8480.(CVE-2014-8481)The     snd_compress_check_input function in     sound/core/compress_offload.c in the ALSA subsystem in     the Linux kernel before 3.17 does not properly check     for an integer overflow, which allows local users to     cause a denial of service (insufficient memory     allocation) or possibly have unspecified other impact     via a crafted SNDRV_COMPRESS_SET_PARAMS ioctl     call.(CVE-2014-9904)The resv_map_release function in     mm/hugetlb.c in the Linux kernel, through 4.15.7,     allows local users to cause a denial of service (BUG)     via a crafted application that makes mmap system calls     and has a large pgoff argument to the remap_file_pages     system call.(CVE-2018-7740)

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)

The SUSE Linux Enterprise 11 SP3 kernel was updated to receive various security fixes. The following security bugs were fixed :

  - CVE-2017-1000364: The default stack guard page was too     small and could be 'jumped over' by userland programs     using more than one page of stack in functions and so     lead to memory corruption. This update extends the stack     guard page to 1 MB (for 4k pages) and 16 MB (for 64k     pages) to reduce this attack vector. This is not a     kernel bugfix, but a hardening measure against this kind     of userland attack.(bsc#1039348)

  - CVE-2015-3288: mm/memory.c in the Linux kernel     mishandled anonymous pages, which allowed local users to     gain privileges or cause a denial of service (page     tainting) via a crafted application that triggers     writing to page zero (bnc#979021).

Updated kernel packages that fix multiple security issues, address several hundred bugs, and add numerous enhancements are now available as part of the ongoing support and maintenance of Red Hat Enterprise Linux version 7. This is the second regular update.

Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

* 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, Important)

* A race condition flaw was found in the way the Linux kernel's IPC subsystem initialized certain fields in an IPC object structure that were later used for permission checking before inserting the object into a globally visible list. A local, unprivileged user could potentially use this flaw to elevate their privileges on the system.
(CVE-2015-7613, Important)

* It was found that reporting emulation failures to user space could lead to either a local (CVE-2014-7842) or a L2->L1 (CVE-2010-5313) denial of service. In the case of a local denial of service, an attacker must have access to the MMIO area or be able to access an I/O port. (CVE-2010-5313, CVE-2014-7842, Moderate)

* A flaw was found in the way the Linux kernel's KVM subsystem handled non-canonical addresses when emulating instructions that change the RIP (for example, branches or calls). A guest user with access to an I/O or MMIO region could use this flaw to crash the guest.
(CVE-2014-3647, Moderate)

* It was found that the Linux kernel memory resource controller's (memcg) handling of OOM (out of memory) conditions could lead to deadlocks. An attacker could use this flaw to lock up the system.
(CVE-2014-8171, Moderate)

* A race condition flaw was found between the chown and execve system calls. A local, unprivileged user could potentially use this flaw to escalate their privileges on the system. (CVE-2015-3339, Moderate)

* 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 a denial of service on the system. (CVE-2015-4170, Moderate)

* A NULL pointer dereference flaw was found in the SCTP implementation. A local user could use this flaw to cause a denial of service on the system by triggering a kernel panic when creating multiple sockets in parallel while the system did not have the SCTP module loaded. (CVE-2015-5283, Moderate)

* A flaw was found in the way the Linux kernel's perf subsystem retrieved userlevel stack traces on PowerPC systems. A local, unprivileged user could use this flaw to cause a denial of service on the system. (CVE-2015-6526, Moderate)

* A flaw was found in the way the Linux kernel's Crypto subsystem handled automatic loading of kernel modules. A local user could use this flaw to load any installed kernel module, and thus increase the attack surface of the running kernel. (CVE-2013-7421, CVE-2014-9644, Low)

* An information leak flaw was found in the way the Linux kernel changed certain segment registers and thread-local storage (TLS) during a context switch. A local, unprivileged user could use this flaw to leak the user space TLS base address of an arbitrary process.
(CVE-2014-9419, Low)

* 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-2015-0239, Low)

* A flaw was found in the way the Linux kernel handled the securelevel functionality after performing a kexec operation. A local attacker could use this flaw to bypass the security mechanism of the securelevel/secureboot combination. (CVE-2015-7837, Low)

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2015:2152 advisory.

    The kernel packages contain the Linux kernel, the core of any Linux     operating system.

    * 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, Important)

    * A race condition flaw was found in the way the Linux kernel's IPC     subsystem initialized certain fields in an IPC object structure that were     later used for permission checking before inserting the object into a     globally visible list. A local, unprivileged user could potentially use     this flaw to elevate their privileges on the system. (CVE-2015-7613,     Important)

    * It was found that reporting emulation failures to user space could lead     to either a local (CVE-2014-7842) or a L2->L1 (CVE-2010-5313) denial of     service. In the case of a local denial of service, an attacker must have     access to the MMIO area or be able to access an I/O port. (CVE-2010-5313,     CVE-2014-7842, Moderate)

    * A flaw was found in the way the Linux kernel's KVM subsystem handled     non-canonical addresses when emulating instructions that change the RIP     (for example, branches or calls). A guest user with access to an I/O or     MMIO region could use this flaw to crash the guest. (CVE-2014-3647,     Moderate)

    * It was found that the Linux kernel memory resource controller's (memcg)     handling of OOM (out of memory) conditions could lead to deadlocks.
    An attacker could use this flaw to lock up the system. (CVE-2014-8171,     Moderate)

    * A race condition flaw was found between the chown and execve system     calls. A local, unprivileged user could potentially use this flaw to     escalate their privileges on the system. (CVE-2015-3339, Moderate)

    * 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 a denial of service on the system. (CVE-2015-4170, Moderate)

    * A NULL pointer dereference flaw was found in the SCTP implementation.
    A local user could use this flaw to cause a denial of service on the system     by triggering a kernel panic when creating multiple sockets in parallel     while the system did not have the SCTP module loaded. (CVE-2015-5283,     Moderate)

    * A flaw was found in the way the Linux kernel's perf subsystem retrieved     userlevel stack traces on PowerPC systems. A local, unprivileged user could     use this flaw to cause a denial of service on the system. (CVE-2015-6526,     Moderate)

    * A flaw was found in the way the Linux kernel's Crypto subsystem handled     automatic loading of kernel modules. A local user could use this flaw to     load any installed kernel module, and thus increase the attack surface of     the running kernel. (CVE-2013-7421, CVE-2014-9644, Low)

    * An information leak flaw was found in the way the Linux kernel changed     certain segment registers and thread-local storage (TLS) during a context     switch. A local, unprivileged user could use this flaw to leak the user     space TLS base address of an arbitrary process. (CVE-2014-9419, Low)

    * 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-2015-0239, Low)

    * A flaw was found in the way the Linux kernel handled the securelevel     functionality after performing a kexec operation. A local attacker could     use this flaw to bypass the security mechanism of the     securelevel/secureboot combination. (CVE-2015-7837, Low)
