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

  - A flaw was found in the way the Linux kernel handled     IRET faults during the processing of NMIs. An     unprivileged, local user could use this flaw to crash     the system or, potentially (although highly unlikely),     escalate their privileges on the system.(CVE-2015-5157)

  - A denial of service vulnerability was found in the     WhiteHEAT USB Serial Driver (whiteheat_attach function     in drivers/usb/serial/whiteheat.c). In the driver, the     COMMAND_PORT variable was hard coded and set to 4 (5th     element). The driver assumed that the number of ports     would always be 5 and used port number 5 as the command     port. However, when using a USB device in which the     number of ports was set to a number less than 5 (for     example, 3), the driver triggered a kernel NULL-pointer     dereference. A non-privileged attacker could use this     flaw to panic the host.(CVE-2015-5257)

  - 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)

  - It was found that the x86 ISA (Instruction Set     Architecture) is prone to a denial of service attack     inside a virtualized environment in the form of an     infinite loop in the microcode due to the way     (sequential) delivering of benign exceptions such as     #AC (alignment check exception) is handled. A     privileged user inside a guest could use this flaw to     create denial of service conditions on the host     kernel.(CVE-2015-5307)

  - A flaw was found in the way the Linux kernel's     networking implementation handled UDP packets with     incorrect checksum values. A remote attacker could     potentially use this flaw to trigger an infinite loop     in the kernel, resulting in a denial of service on the     system, or cause a denial of service in applications     using the edge triggered epoll     functionality.(CVE-2015-5364)

  - A flaw was found in the way the Linux kernel's     networking implementation handled UDP packets with     incorrect checksum values. A remote attacker could     potentially use this flaw to trigger an infinite loop     in the kernel, resulting in a denial of service on the     system, or cause a denial of service in applications     using the edge triggered epoll     functionality.(CVE-2015-5366)

  - A cross-boundary flaw was discovered in the Linux     kernel software raid driver. The driver accessed a     disabled bitmap where only the first byte of the buffer     was initialized to zero. This meant that the rest of     the request (up to 4095 bytes) was left and copied into     user space. An attacker could use this flaw to read     private information from user space that would not     otherwise have been accessible.(CVE-2015-5697)

  - An integer-overflow vulnerability was found in the scsi     block-request handling code in function start_req(). A     local attacker could use specially crafted IOV requests     to overflow a counter used in bio_map_user_iov()'s page     calculation, and write past the end of the array that     contains kernel-page pointers.(CVE-2015-5707)

  - A flaw was found in the way the Linux kernel's vhost     driver treated userspace provided log file descriptor     when processing the VHOST_SET_LOG_FD ioctl command. The     file descriptor was never released and continued to     consume kernel memory. A privileged local user with     access to the /dev/vhost-net files could use this flaw     to create a denial-of-service attack.(CVE-2015-6252)

  - 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 by creating     a special stack layout that would force the     perf_callchain_user_64() function into an infinite     loop.(CVE-2015-6526)

  - A NULL-pointer dereference vulnerability was discovered     in the Linux kernel. The kernel's Reliable Datagram     Sockets (RDS) protocol implementation did not verify     that an underlying transport existed before creating a     connection to a remote server. A local system user     could exploit this flaw to crash the system by creating     sockets at specific times to trigger a NULL pointer     dereference.(CVE-2015-6937)

  - Multiple race conditions in the Advanced Union     Filesystem (aufs) aufs3-mmap.patch and aufs4-mmap.patch     patches for the Linux kernel 3.x and 4.x allow local     users to cause a denial of service (use-after-free and     BUG) or possibly gain privileges via a (1) madvise or     (2) msync system call, related to mm/madvise.c and     mm/msync.c.(CVE-2015-7312)

  - A divide-by-zero flaw was discovered in the Linux     kernel built with KVM virtualization     support(CONFIG_KVM). The flaw occurs in the KVM     module's Programmable Interval Timer(PIT) emulation,     when PIT counters for channel 1 or 2 are set to zero(0)     and a privileged user inside the guest attempts to read     these counters. A privileged guest user with access to     PIT I/O ports could exploit this issue to crash the     host kernel (denial of service).(CVE-2015-7513)

  - An out-of-bounds memory access flaw was found in the     Linux kernel's aiptek USB tablet driver (aiptek_probe()     function in drivers/input/tablet/aiptek.c). The driver     assumed that the interface always had at least one     endpoint. By using a specially crafted USB device with     no endpoints on one of its interfaces, an unprivileged     user with physical access to the system could trigger a     kernel NULL pointer dereference, causing the system to     panic.(CVE-2015-7515)

  - A NULL-pointer dereference flaw was found in the     kernel, which is caused by a race between revoking a     user-type key and reading from it. The issue could be     triggered by an unprivileged user with a local account,     causing the kernel to crash (denial of     service).(CVE-2015-7550)

  - A flaw was found in the way the Linux kernel visor     driver handles certain invalid USB device descriptors.
    The driver assumes that the device always has at least     one bulk OUT endpoint. By using a specially crafted USB     device (without a bulk OUT endpoint), an unprivileged     user with physical access could trigger a kernel     NULL-pointer dereference and cause a system panic     (denial of service).(CVE-2015-7566)

  - 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)

  - A flaw was discovered in the Linux kernel where issuing     certain ioctl() -s commands to the '/dev/ppp' device     file could lead to a NULL pointer dereference. A     privileged user could use this flaw to cause a kernel     crash and denial of service.(CVE-2015-7799)

  - It was found that the Linux kernel's keys subsystem did     not correctly garbage collect uninstantiated keyrings.
    A local attacker could use this flaw to crash the     system or, potentially, escalate their privileges on     the system.(CVE-2015-7872)

  - 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)

  - It was found that the x86 ISA (Instruction Set     Architecture) is prone to a denial of service attack     inside a virtualized environment in the form of an     infinite loop in the microcode due to the way     (sequential) delivering of benign exceptions such as     #DB (debug exception) is handled. A privileged user     inside a guest could use this flaw to create denial of     service conditions on the host kernel.(CVE-2015-8104)

  - It was found that the Linux kernel's IPv6 network stack     did not properly validate the value of the MTU variable     when it was set. A remote attacker could potentially     use this flaw to disrupt a target system's networking     (packet loss) by setting an invalid MTU value, for     example, via a NetworkManager daemon that is processing     router advertisement packets running on the target     system.(CVE-2015-8215)

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The vhost_dev_ioctl function in drivers/vhost/vhost.c in the Linux kernel before 4.1.5 allows local users     to cause a denial of service (memory consumption) via a VHOST_SET_LOG_FD ioctl call that triggers     permanent file-descriptor allocation. (CVE-2015-6252)

Note that Nessus relies on the presence of the package as reported by the vendor.

The SUSE Linux Enterprise 12 kernel was updated to 3.12.48-52.27 to receive various security and bugfixes.

Following security bugs were fixed :

  - CVE-2015-7613: A flaw was found in the Linux kernel IPC     code that could lead to arbitrary code execution. The     ipc_addid() function initialized a shared object that     has unset uid/gid values. Since the fields are not     initialized, the check can falsely succeed. (bsc#948536)

  - CVE-2015-5156: When a guests KVM network devices is in a     bridge configuration the kernel can create a situation     in which packets are fragmented in an unexpected     fashion. The GRO functionality can create a situation in     which multiple SKB's are chained together in a single     packets fraglist (by design). (bsc#940776)

  - CVE-2015-5157: arch/x86/entry/entry_64.S in the Linux     kernel before 4.1.6 on the x86_64 platform mishandles     IRET faults in processing NMIs that occurred during     userspace execution, which might allow local users to     gain privileges by triggering an NMI (bsc#938706).

  - CVE-2015-6252: A flaw was found in the way the Linux     kernel's vhost driver treated userspace provided log     file descriptor when processing the VHOST_SET_LOG_FD     ioctl command. The file descriptor was never released     and continued to consume kernel memory. A privileged     local user with access to the /dev/vhost-net files could     use this flaw to create a denial-of-service attack     (bsc#942367).

  - CVE-2015-5697: The get_bitmap_file function in     drivers/md/md.c in the Linux kernel before 4.1.6 does     not initialize a certain bitmap data structure, which     allows local users to obtain sensitive information from     kernel memory via a GET_BITMAP_FILE ioctl call.
    (bnc#939994)

  - CVE-2015-6937: A NULL pointer dereference flaw was found     in the Reliable Datagram Sockets (RDS) implementation     allowing a local user to cause system DoS. A     verification was missing that the underlying transport     exists when a connection was created. (bsc#945825)

  - CVE-2015-5283: A NULL pointer dereference flaw was found     in SCTP implementation allowing a local user to cause     system DoS. Creation of multiple sockets in parallel     when system doesn't have SCTP module loaded can lead to     kernel panic. (bsc#947155)

The update package also includes non-security fixes. See advisory for details.

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

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

  - CVE-2015-8215     It was discovered that NetworkManager would set IPv6     MTUs based on the values received in IPv6 RAs (Router     Advertisements), without sufficiently validating these     values. A remote attacker could exploit this attack to     disable IPv6 connectivity. This has been mitigated by     adding validation in the kernel.

  - CVE-2015-2925     Jann Horn discovered that when a subdirectory of a     filesystem is bind-mounted into a container that has its     own user and mount namespaces, a process with     CAP_SYS_ADMIN capability in the user namespace can     access files outside of the subdirectory. The default     Debian configuration mitigated this as it does not allow     unprivileged users to create new user namespaces.

  - CVE-2015-5156     Jason Wang discovered that when a virtio_net device is     connected to a bridge in the same VM, a series of TCP     packets forwarded through the bridge may cause a heap     buffer overflow. A remote attacker could use this to     cause a denial of service (crash) or possibly for     privilege escalation.

  - CVE-2015-6252     Michael S. Tsirkin of Red Hat Engineering found that the     vhost driver leaked file descriptors passed to it with     the VHOST_SET_LOG_FD ioctl command. A privileged local     user with access to the /dev/vhost-net file, either     directly or via libvirt, could use this to cause a     denial of service (hang or crash).

  - CVE-2015-6937     It was found that the Reliable Datagram Sockets (RDS)     protocol implementation did not verify that an     underlying transport exists when creating a connection.
    Depending on how a local RDS application initialised its     sockets, a remote attacker might be able to cause a     denial of service (crash) by sending a crafted packet.

  - CVE-2015-7312     Xavier Chantry discovered that the patch provided by the     aufs project to correct behaviour of memory-mapped files     from an aufs mount introduced a race condition in the     msync() system call. Ben Hutchings found that it also     introduced a similar bug in the madvise_remove()     function. A local attacker could use this to cause a     denial of service or possibly for privilege escalation.

The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes.

Following security bugs were fixed :

  - CVE-2015-6252: Possible file descriptor leak for each     VHOST_SET_LOG_FDcommand issued, this could eventually     wasting available system resources and creating a denial     of service (bsc#942367).

  - CVE-2015-5707: Possible integer overflow in the     calculation of total number of pages in     bio_map_user_iov() (bsc#940338).

  - CVE-2015-5364: The (1) udp_recvmsg and (2) udpv6_recvmsg     functions in the Linux kernel before 4.0.6 do not     properly consider yielding a processor, which allowed     remote attackers to cause a denial of service (system     hang) via incorrect checksums within a UDP packet flood     (bsc#936831).

  - CVE-2015-5366: The (1) udp_recvmsg and (2) udpv6_recvmsg     functions in the Linux kernel before 4.0.6 provide     inappropriate -EAGAIN return values, which allowed     remote attackers to cause a denial of service (EPOLLET     epoll application read outage) via an incorrect checksum     in a UDP packet, a different vulnerability than     CVE-2015-5364 (bsc#936831).

  - CVE-2015-1420: Race condition in the handle_to_path     function in fs/fhandle.c in the Linux kernel through     3.19.1 allowed 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     (bsc#915517).

  - CVE-2015-1805: The (1) pipe_read and (2) pipe_write     implementations in fs/pipe.c in the Linux kernel before     3.16 do not properly consider the side effects of failed
    __copy_to_user_inatomic and __copy_from_user_inatomic     calls, which allows local users to cause a denial of     service (system crash) or possibly gain privileges via a     crafted application, aka an 'I/O' vector array overrun.
    (bsc#933429)

  - CVE-2015-2150: 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     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. (bsc#919463)

  - CVE-2015-2830: arch/x86/kernel/entry_64.S in the Linux     kernel before 3.19.2 does not prevent the TS_COMPAT flag     from reaching a user-mode task, which might allow local     users to bypass the seccomp or audit protection     mechanism via a crafted application that uses the (1)     fork or (2) close system call, as demonstrated by an     attack against seccomp before 3.16. (bsc#926240)

  - CVE-2015-4700: The bpf_int_jit_compile function in     arch/x86/net/bpf_jit_comp.c in the Linux kernel before     4.0.6 allowed local users to cause a denial of service     (system crash) by creating a packet filter and then     loading crafted BPF instructions that trigger late     convergence by the JIT compiler (bsc#935705).

  - CVE-2015-4167: The udf_read_inode function in     fs/udf/inode.c in the Linux kernel before 3.19.1 did not     validate certain length values, which allowed local     users to cause a denial of service (incorrect data     representation or integer overflow, and OOPS) via a     crafted UDF filesystem (bsc#933907).

  - CVE-2015-0777: drivers/xen/usbback/usbback.c in     linux-2.6.18-xen-3.4.0 (aka the Xen 3.4.x support     patches for the Linux kernel 2.6.18), as used in the     Linux kernel 2.6.x and 3.x in SUSE Linux distributions,     allows guest OS users to obtain sensitive information     from uninitialized locations in host OS kernel memory     via unspecified vectors. (bsc#917830)

  - CVE-2014-9728: The UDF filesystem implementation in the     Linux kernel before 3.18.2 did not validate certain     lengths, which allowed local users to cause a denial of     service (buffer over-read and system crash) via a     crafted filesystem image, related to fs/udf/inode.c and     fs/udf/symlink.c (bsc#933904).

  - CVE-2014-9730: The udf_pc_to_char function in     fs/udf/symlink.c in the Linux kernel before 3.18.2     relies on component lengths that are unused, which     allowed local users to cause a denial of service (system     crash) via a crafted UDF filesystem image (bsc#933904).

  - CVE-2014-9729: The udf_read_inode function in     fs/udf/inode.c in the Linux kernel before 3.18.2 did not     ensure a certain data-structure size consistency, which     allowed local users to cause a denial of service (system     crash) via a crafted UDF filesystem image (bsc#933904).

  - CVE-2014-9731: The UDF filesystem implementation in the     Linux kernel before 3.18.2 did not ensure that space is     available for storing a symlink target's name along with     a trailing \0 character, which allowed local users to     obtain sensitive information via a crafted filesystem     image, related to fs/udf/symlink.c and fs/udf/unicode.c     (bsc#933896).

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):Use-after-free     vulnerability in driverset/tun.c in the Linux kernel     through 3.11.1 allows local users to gain privileges by     leveraging the CAP_NET_ADMIN capability and providing     an invalid tuntap interface name in a TUNSETIFF ioctl     call.(CVE-2013-4343)It was found that when the gcc     stack protector was enabled, reading the /proc/keys     file could cause a panic in the Linux kernel due to     stack corruption. This happened because an incorrect     buffer size was used to hold a 64-bit timeout value     rendered as weeks.(CVE-2016-7042)A flaw was found in     the Linux kernel that fs/ocfs2/aops.c omits use of a     semaphore and consequently has a race condition for     access to the extent tree during read operations in     DIRECT mode. This allows local users to cause a denial     of service by modifying a certain e_cpos     field.(CVE-2017-18224)The sctp_v6_create_accept_sk     function in net/sctp/ipv6.c in the Linux kernel     mishandles inheritance, which allows local users to     cause a denial of service or possibly have unspecified     other impact via crafted system calls, a related issue     to CVE-2017-8890. An unprivileged local user could use     this flaw to induce kernel memory corruption on the     system, leading to a crash. Due to the nature of the     flaw, privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2017-9075)In     the function sbusfb_ioctl_helper() in     drivers/video/fbdev/sbuslib.c in the Linux kernel, up     to and including 4.15, an integer signedness error     allows arbitrary information leakage for the     FBIOPUTCMAP_SPARC and FBIOGETCMAP_SPARC     commands.(CVE-2018-6412)A race condition flaw was found     in the way the Linux kernel's mmap(2), madvise(2), and     fallocate(2) system calls interacted with each other     while operating on virtual memory file system files. A     local user could use this flaw to cause a denial of     service.(CVE-2014-4171)** RESERVED ** This candidate     has been reserved by an organization or individual that     will use it when announcing a new security problem.
    When the candidate has been publicized, the details for     this candidate will be provided.(CVE-2018-1095)A NULL     pointer dereference flaw was found in the way the Linux     kernel's Stream Control Transmission Protocol (SCTP)     implementation handled simultaneous connections between     the same hosts. A remote attacker could use this flaw     to crash the system.(CVE-2014-5077)A vulnerability was     found in the fs/inode.c:inode_init_owner() function     logic of the LInux kernel that allows local users to     create files with an unintended group ownership and     with group execution and SGID permission bits set, in a     scenario where a directory is SGID and belongs to a     certain group and is writable by a user who is not a     member of this group. This can lead to excessive     permissions granted in case when they should     not.(CVE-2018-13405)In the Linux kernel before 4.20.8,     kvm_ioctl_create_device in virt/kvm/kvm_main.c     mishandles reference counting because of a race     condition, leading to a use-after-free.(CVE-2019-6974)A     flaw was found in the way Linux kernel allocates heap     memory to build the scattergather list from a fragment     list(skb_shinfo(skb)-i1/4zfrag_list) in the socket     buffer(skb_buff). The heap overflow occurred if     'MAX_SKB_FRAGS + 1' parameter and 'NETIF_F_FRAGLIST'     feature are both used together. A remote user or     process could use this flaw to potentially escalate     their privilege on a system.(CVE-2017-7477)Multiple     integer overflows in Alchemy LCD frame-buffer drivers     in the Linux kernel before 3.12 allow local users to     create a read-write memory mapping for the entirety of     kernel memory, and consequently gain privileges, via     crafted mmap operations, related to the (1)     au1100fb_fb_mmap function in drivers/video/au1100fb.c     and the (2) au1200fb_fb_mmap function in     drivers/video/au1200fb.c.(CVE-2013-4511)It was found     that in the Linux kernel through v4.14-rc5,     bio_map_user_iov() and bio_unmap_user() in     'block/bio.c' do unbalanced pages refcounting if IO     vector has small consecutive buffers belonging to the     same page. bio_add_pc_page() merges them into one, but     the page reference is never dropped, causing a memory     leak and possible system lockup due to out-of-memory     condition.(CVE-2017-12190)An issue was discovered in     the Linux kernel before 4.19.3. crypto_report_one() and     related functions in crypto/crypto_user.c (the crypto     user configuration API) do not fully initialize     structures that are copied to userspace, potentially     leaking sensitive memory to user programs. NOTE: this     is a CVE-2013-2547 regression but with easier     exploitability because the attacker does not need a     capability (however, the system must have the     CONFIG_CRYPTO_USER kconfig option).(CVE-2018-19854)The     userfaultfd implementation in the Linux kernel before     4.19.7 mishandles access control for certain UFFDIO_     ioctl calls, as demonstrated by allowing local users to     write data into holes in a tmpfs file (if the user has     read-only access to that file, and that file contains     holes), related to fs/userfaultfd.c and     mm/userfaultfd.c.(CVE-2018-18397)The TCP stack in the     Linux kernel through 4.10.6 mishandles the     SCM_TIMESTAMPING_OPT_STATS feature, which allows local     users to obtain sensitive information from the kernel's     internal socket data structures or cause a denial of     service (out-of-bounds read) via crafted system calls,     related to net/core/skbuff.c and     net/socket.c.(CVE-2017-7277)A flaw was found in the way     the Linux kernel's vhost driver treated userspace     provided log file descriptor when processing the     VHOST_SET_LOG_FD ioctl command. The file descriptor was     never released and continued to consume kernel memory.
    A privileged local user with access to the     /dev/vhost-net files could use this flaw to create a     denial-of-service attack.(CVE-2015-6252)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 MSM QDSP6     audio driver (aka sound driver) for the Linux kernel     3.x, as used in Qualcomm Innovation Center (QuIC)     Android contributions for MSM devices and other     products, allows attackers to gain privileges or cause     a denial of service (integer overflow, and buffer     overflow or buffer over-read) via a crafted application     that performs a (1) AUDIO_EFFECTS_WRITE or (2)     AUDIO_EFFECTS_READ operation, aka Qualcomm internal bug     CR1006609.(CVE-2016-2068)The icmp6_send function in     net/ipv6/icmp.c in the Linux kernel through 4.8.12     omits a certain check of the dst data structure which     allows remote attackers to cause a denial of service     (panic) via a fragmented IPv6 packet.(CVE-2016-9919)
