The IPv4 implementation in the Linux kernel before 3.18.8 does not properly consider the length of the Read-Copy Update (RCU) grace period for redirecting lookups in the absence of caching, which allows remote attackers to cause a denial of service (memory consumption or system crash) via a flood of packets.

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 :

  - drivers/gpu/msm/kgsl.c in the MSM graphics driver (aka     GPU driver) for the Linux kernel 3.x, as used in     Qualcomm Innovation Center (QuIC) Android contributions     for MSM devices and other products, mishandles the     KGSL_MEMFLAGS_GPUREADONLY flag, which allows attackers     to gain privileges by leveraging accidental read-write     mappings, aka Qualcomm internal bug     CR988993.(CVE-2016-2067i1/4%0

  - Integer overflow in the mem_check_range function in     drivers/infiniband/sw/rxe/rxe_mr.c in the Linux kernel     before 4.9.10 allows local users to cause a denial of     service (memory corruption), obtain sensitive     information from kernel memory, or possibly have     unspecified other impact via a write or read request     involving the 'RDMA protocol over infiniband' (aka Soft     RoCE) technology.(CVE-2016-8636i1/4%0

  - Heap-based buffer overflow in the     logi_dj_ll_raw_request function in     drivers/hid/hid-logitech-dj.c in the Linux kernel     before 3.16.2 allows physically proximate attackers to     cause a denial of service (system crash) or possibly     execute arbitrary code via a crafted device that     specifies a large report size for an LED     report.(CVE-2014-3183i1/4%0

  - The futex_requeue function in kernel/futex.c in the     Linux kernel, before 4.14.15, might allow attackers to     cause a denial of service (integer overflow) or     possibly have unspecified other impacts by triggering a     negative wake or requeue value. Due to the nature of     the flaw, privilege escalation cannot be fully ruled     out, although we believe it is     unlikely.(CVE-2018-6927i1/4%0

  - The hub_activate function in drivers/usb/core/hub.c in     the Linux kernel before 4.3.5 does not properly     maintain a hub-interface data structure, which allows     physically proximate attackers to cause a denial of     service (invalid memory access and system crash) or     possibly have unspecified other impact by unplugging a     USB hub device.(CVE-2015-8816i1/4%0

  - It was found that the blk_rq_map_user_iov() function in     the Linux kernel's block device implementation did not     properly restrict the type of iterator, which could     allow a local attacker to read or write to arbitrary     kernel memory locations or cause a denial of service     (use-after-free) by leveraging write access to a     /dev/sg device.(CVE-2016-9576i1/4%0

  - A security flaw was found in the Linux kernel's     networking subsystem that destroying the network     interface with huge number of ipv4 addresses assigned     keeps 'rtnl_lock' spinlock for a very long time (up to     hour). This blocks many network-related operations,     including creation of new incoming ssh connections.The     problem is especially important for containers, as the     container owner has enough permissions to trigger this     and block a network access on a whole host, outside the     container.(CVE-2016-3156i1/4%0

  - The edge_bulk_in_callback function in     drivers/usb/serial/io_ti.c in the Linux kernel allows     local users to obtain sensitive information (in the     dmesg ringbuffer and syslog) from uninitialized kernel     memory by using a crafted USB device (posing as an     io_ti USB serial device) to trigger an integer     underflow.(CVE-2017-8924i1/4%0

  - The IPv4 implementation in the Linux kernel before     3.18.8 does not properly consider the length of the     Read-Copy Update (RCU) grace period for redirecting     lookups in the absence of caching, which allows remote     attackers to cause a denial of service (memory     consumption or system crash) via a flood of     packets.(CVE-2015-1465i1/4%0

  - A symlink size validation was missing in Linux kernels     built with UDF file system (CONFIG_UDF_FS) support,     allowing the corruption of kernel memory. An attacker     able to mount a corrupted/malicious UDF file system     image could cause the kernel to crash.(CVE-2014-9728i1/4%0

  - net/ipv6/ip6_output.c in the Linux kernel through     3.11.4 does not properly determine the need for UDP     Fragmentation Offload (UFO) processing of small packets     after the UFO queueing of a large packet, which allows     remote attackers to cause a denial of service (memory     corruption and system crash) or possibly have     unspecified other impact via network traffic that     triggers a large response packet.(CVE-2013-4387i1/4%0

  - It was found that nfsd is missing permissions check     when setting ACL on files, this may allow a local users     to gain access to any file by setting a crafted     ACL.(CVE-2016-1237i1/4%0

  - In the Linux kernel before 4.13.5, a local user could     create keyrings for other users via keyctl commands,     setting unwanted defaults or causing a denial of     service.(CVE-2017-18270i1/4%0

  - An issue was discovered in the Linux kernel where an     integer overflow in kernel/time/posix-timers.c in the     POSIX timer code is caused by the way the overrun     accounting works. Depending on interval and expiry time     values, the overrun can be larger than INT_MAX, but the     accounting is int based. This basically makes the     accounting values, which are visible to user space via     timer_getoverrun(2) and siginfo::si_overrun,     random.(CVE-2018-12896i1/4%0

  - Since Linux kernel version 3.2, the mremap() syscall     performs TLB flushes after dropping pagetable locks. If     a syscall such as ftruncate() removes entries from the     pagetables of a task that is in the middle of mremap(),     a stale TLB entry can remain for a short time that     permits access to a physical page after it has been     released back to the page allocator and reused. This is     fixed in the following kernel versions: 4.9.135,     4.14.78, 4.18.16, 4.19.(CVE-2018-18281i1/4%0

  - The netfilter subsystem in the Linux kernel through     4.15.7 mishandles the case of a rule blob that contains     a jump but lacks a user-defined chain, which allows     local users to cause a denial of service (NULL pointer     dereference) by leveraging the CAP_NET_RAW or     CAP_NET_ADMIN capability, related to arpt_do_table in     net/ipv4/netfilter/arp_tables.c, ipt_do_table in     net/ipv4/netfilter/ip_tables.c, and ip6t_do_table in     net/ipv6/netfilter/ip6_tables.c.(CVE-2018-1065i1/4%0

  - The use of a kzalloc with an integer multiplication     allowed an integer overflow condition to be reached in     vfio_pci_intrs.c. This combined with CVE-2016-9083 may     allow an attacker to craft an attack and use     unallocated memory, potentially crashing the     machine.(CVE-2016-9084i1/4%0

  - The acm_probe function in drivers/usb/class/cdc-acm.c     in the Linux kernel before 4.5.1 allows physically     proximate attackers to cause a denial of service (NULL     pointer dereference and system crash) via a USB device     without both a control and a data endpoint     descriptor.(CVE-2016-3138i1/4%0

  - It was discovered that root can gain direct access to     an internal keyring, such as '.dns_resolver' in RHEL-7     or '.builtin_trusted_keys' upstream, by joining it as     its session keyring. This allows root to bypass module     signature verification by adding a new public key of     its own devising to the keyring.(CVE-2016-9604i1/4%0

  - An information leak flaw was found in the Linux     kernel's IEEE 802.11 wireless networking     implementation. When software encryption was used, a     remote attacker could use this flaw to leak up to 8     bytes of plaintext.(CVE-2014-8709i1/4%0

    A local user could use this flaw to load any installed     kernel module, and thus increase the attack surface of     the running kernel.(CVE-2014-9644)

  - The Btrfs implementation in the Linux kernel before     3.19 does not ensure that the visible xattr state is     consistent with a requested replacement, which allows     local users to bypass intended ACL settings and gain     privileges via standard filesystem operations (1)     during an xattr-replacement time window, related to a     race condition, or (2) after an xattr-replacement     attempt that fails because the data does not     fit.(CVE-2014-9710)

  - An integer overflow flaw was found in the way the Linux     kernel's netfilter connection tracking implementation     loaded extensions. An attacker on a local network could     potentially send a sequence of specially crafted     packets that would initiate the loading of a large     number of extensions, causing the targeted system in     that network to crash.(CVE-2014-9715)

  - A symlink size validation was missing in Linux kernels     built with UDF file system (CONFIG_UDF_FS) support,     allowing the corruption of kernel memory. An attacker     able to mount a corrupted/malicious UDF file system     image could cause the kernel to crash.(CVE-2014-9728)

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)

  - A flaw was found in the way the Linux kernel's XFS file     system handled replacing of remote attributes under     certain conditions. A local user with access to XFS     file system mount could potentially use this flaw to     escalate their privileges on the system.(CVE-2015-0274)

  - Race condition in the handle_to_path function in     fs/fhandle.c in the Linux kernel through 3.19.1 allows     local users to bypass intended size restrictions and     trigger read operations on additional memory locations     by changing the handle_bytes value of a file handle     during the execution of this function.(CVE-2015-1420)

  - A use-after-free flaw was found in the way the Linux     kernel's SCTP implementation handled authentication key     reference counting during INIT collisions. A remote     attacker could use this flaw to crash the system or,     potentially, escalate their privileges on the     system.(CVE-2015-1421)

  - The IPv4 implementation in the Linux kernel before     3.18.8 does not properly consider the length of the     Read-Copy Update (RCU) grace period for redirecting     lookups in the absence of caching, which allows remote     attackers to cause a denial of service (memory     consumption or system crash) via a flood of     packets.(CVE-2015-1465)

  - An integer overflow flaw was found in the way the Linux     kernel randomized the stack for processes on certain     64-bit architecture systems, such as x86-64, causing     the stack entropy to be reduced by four.(CVE-2015-1593)

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.

The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2017-3658 advisory.

  - The ping_unhash function in net/ipv4/ping.c in the Linux kernel through 4.10.8 is too late in obtaining a     certain lock and consequently cannot ensure that disconnect function calls are safe, which allows local     users to cause a denial of service (panic) by leveraging access to the protocol value of IPPROTO_ICMP in a     socket system call. (CVE-2017-2671)

  - The mm subsystem in the Linux kernel through 3.2 does not properly enforce the CONFIG_STRICT_DEVMEM     protection mechanism, which allows local users to read or write to kernel memory locations in the first     megabyte (and bypass slab-allocation access restrictions) via an application that opens the /dev/mem file,     related to arch/x86/mm/init.c and drivers/char/mem.c. (CVE-2017-7889)

  - The bio_map_user_iov and bio_unmap_user functions in block/bio.c in the Linux kernel before 4.13.8 do     unbalanced refcounting when a SCSI I/O vector has small consecutive buffers belonging to the same page.
    The bio_add_pc_page function merges them into one, but the page reference is never dropped. This causes a     memory leak and possible system lockup (exploitable against the host OS by a guest OS user, if a SCSI disk     is passed through to a virtual machine) due to an out-of-memory condition. (CVE-2017-12190)

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

  - The cp_report_fixup function in drivers/hid/hid-cypress.c in the Linux kernel 3.2 and 4.x before 4.9.4     allows physically proximate attackers to cause a denial of service (integer underflow) or possibly have     unspecified other impact via a crafted HID report. (CVE-2017-7273)

  - The Btrfs implementation in the Linux kernel before 3.19 does not ensure that the visible xattr state is     consistent with a requested replacement, which allows local users to bypass intended ACL settings and gain     privileges via standard filesystem operations (1) during an xattr-replacement time window, related to a     race condition, or (2) after an xattr-replacement attempt that fails because the data does not fit.
    (CVE-2014-9710)

  - net/socket.c in the Linux kernel 3.19 before 3.19.3 does not validate certain range data for (1) sendto     and (2) recvfrom system calls, which allows local users to gain privileges by leveraging a subsystem that     uses the copy_from_iter function in the iov_iter interface, as demonstrated by the Bluetooth subsystem.
    (CVE-2015-2686)

  - The IPv4 implementation in the Linux kernel before 3.18.8 does not properly consider the length of the     Read-Copy Update (RCU) grace period for redirecting lookups in the absence of caching, which allows remote     attackers to cause a denial of service (memory consumption or system crash) via a flood of packets.
    (CVE-2015-1465)

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

The SUSE Linux Enterprise 12 kernel was updated to version 3.12.43 to receive various security and bugfixes.

Following security bugs were fixed :

  - CVE-2014-3647: arch/x86/kvm/emulate.c in the KVM     subsystem in the Linux kernel through 3.17.2 did not     properly perform RIP changes, which allowed guest OS     users to cause a denial of service (guest OS crash) via     a crafted application (bsc#899192).

  - CVE-2014-8086: Race condition in the     ext4_file_write_iter function in fs/ext4/file.c in the     Linux kernel through 3.17 allowed local users to cause a     denial of service (file unavailability) via a     combination of a write action and an F_SETFL fcntl     operation for the O_DIRECT flag (bsc#900881).

  - CVE-2014-8159: The InfiniBand (IB) implementation did     not properly restrict use of User Verbs for registration     of memory regions, which allowed local users to access     arbitrary physical memory locations, and consequently     cause a denial of service (system crash) or gain     privileges, by leveraging permissions on a uverbs device     under /dev/infiniband/ (bsc#914742).

  - CVE-2015-1465: The IPv4 implementation in the Linux     kernel before 3.18.8 did not properly consider the     length of the Read-Copy Update (RCU) grace period for     redirecting lookups in the absence of caching, which     allowed remote attackers to cause a denial of service     (memory consumption or system crash) via a flood of     packets (bsc#916225).

  - CVE-2015-2041: net/llc/sysctl_net_llc.c in the Linux     kernel before 3.19 used an incorrect data type in a     sysctl table, which allowed local users to obtain     potentially sensitive information from kernel memory or     possibly have unspecified other impact by accessing a     sysctl entry (bsc#919007).

  - CVE-2015-2042: net/rds/sysctl.c in the Linux kernel     before 3.19 used an incorrect data type in a sysctl     table, which allowed local users to obtain potentially     sensitive information from kernel memory or possibly     have unspecified other impact by accessing a sysctl     entry (bsc#919018).

  - CVE-2015-2666: Fixed a flaw that allowed crafted     microcode to overflow the kernel stack (bsc#922944).

  - CVE-2015-2830: Fixed int80 fork from 64-bit tasks     mishandling (bsc#926240).

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-2563-1 advisory.

  - Use-after-free vulnerability in the sctp_assoc_update function in net/sctp/associola.c in the Linux kernel     before 3.18.8 allows remote attackers to cause a denial of service (slab corruption and panic) or possibly     have unspecified other impact by triggering an INIT collision that leads to improper handling of shared-     key data. (CVE-2015-1421)

  - The IPv4 implementation in the Linux kernel before 3.18.8 does not properly consider the length of the     Read-Copy Update (RCU) grace period for redirecting lookups in the absence of caching, which allows remote     attackers to cause a denial of service (memory consumption or system crash) via a flood of packets.
    (CVE-2015-1465)

  - The stack randomization feature in the Linux kernel before 3.19.1 on 64-bit platforms uses incorrect data     types for the results of bitwise left-shift operations, which makes it easier for attackers to bypass the     ASLR protection mechanism by predicting the address of the top of the stack, related to the     randomize_stack_top function in fs/binfmt_elf.c and the stack_maxrandom_size function in     arch/x86/mm/mmap.c. (CVE-2015-1593)

  - 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)

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

Sun Baoliang discovered a use after free flaw in the Linux kernel's SCTP (Stream Control Transmission Protocol) subsystem during INIT collisions. A remote attacker could exploit this flaw to cause a denial of service (system crash) or potentially escalate their privileges on the system. (CVE-2015-1421)

Marcelo Leitner discovered a flaw in the Linux kernel's routing of packets to too many different dsts/too fast. A remote attacker can exploit this flaw to cause a denial of service (system crash).
(CVE-2015-1465)

An integer overflow was discovered in the stack randomization feature of the Linux kernel on 64 bit platforms. A local attacker could exploit this flaw to bypass the Address Space Layout Randomization (ASLR) protection mechanism. (CVE-2015-1593)

An information leak was discovered in the Linux Kernel's handling of userspace configuration of the link layer control (LLC). A local user could exploit this flaw to read data from other sysctl settings.
(CVE-2015-2041)

An information leak was discovered in how the Linux kernel handles setting the Reliable Datagram Sockets (RDS) settings. A local user could exploit this flaw to read data from other sysctl settings.
(CVE-2015-2042).

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

A flaw was discovered in the automatic loading of modules in the crypto subsystem of the Linux kernel. A local user could exploit this flaw to load installed kernel modules, increasing the attack surface and potentially using this to gain administrative privileges.
(CVE-2013-7421)

A flaw was discovered in the crypto subsystem when screening module names for automatic module loading if the name contained a valid crypto module name, eg. vfat(aes). A local user could exploit this flaw to load installed kernel modules, increasing the attack surface and potentially using this to gain administrative privileges.
(CVE-2014-9644)
