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'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-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)

  - 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-2014-9729)

  - 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-2014-9730)

  - A path length checking flaw 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 use this flaw to leak kernel memory     to user-space.(CVE-2014-9731)

  - The snd_compr_tstamp function in     sound/core/compress_offload.c in the Linux kernel     through 4.7, as used in Android before 2016-08-05 on     Nexus 5 and 7 (2013) devices, does not properly     initialize a timestamp data structure, which allows     attackers to obtain sensitive information via a crafted     application, aka Android internal bug 28770164 and     Qualcomm internal bug CR568717.(CVE-2014-9892)

  - drivers/media/media-device.c in the Linux kernel before     3.11, as used in Android before 2016-08-05 on Nexus 5     and 7 (2013) devices, does not properly initialize     certain data structures, which allows local users to     obtain sensitive information via a crafted application,     aka Android internal bug 28750150 and Qualcomm internal     bug CR570757, a different vulnerability than     CVE-2014-1739.(CVE-2014-9895)

  - The ethtool_get_wol function in net/core/ethtool.c in     the Linux kernel through 4.7, as used in Android before     2016-08-05 on Nexus 5 and 7 (2013) devices, does not     initialize a certain data structure, which allows local     users to obtain sensitive information via a crafted     application, aka Android internal bug 28803952 and     Qualcomm internal bug CR570754.(CVE-2014-9900)

  - 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)

  - A race condition in the ip4_datagram_release_cb     function in net/ipv4/datagram.c in the Linux kernel     allows local users to gain privileges or cause a denial     of service (use-after-free) by leveraging incorrect     expectations about locking during multithreaded access     to internal data structures for IPv4 UDP     sockets.(CVE-2014-9914)

  - A flaw was discovered in the way the kernel allows     stackable filesystems to overlay. A local attacker who     is able to mount filesystems can abuse this flaw to     escalate privileges.(CVE-2014-9922)

  - The regulator_ena_gpio_free function in     drivers/regulator/core.c in the Linux kernel allows     local users to gain privileges or cause a denial of     service (use-after-free) via a crafted     application.(CVE-2014-9940)

  - 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)

  - 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)

  - A flaw was found in the way the Linux kernel's ext4     file system handled the 'page size i1/4z block size'     condition when the fallocate zero range functionality     was used. A local attacker could use this flaw to crash     the system.(CVE-2015-0275)

  - It was found that the Linux kernel's keyring     implementation would leak memory when adding a key to a     keyring via the add_key() function. A local attacker     could use this flaw to exhaust all available memory on     the system.(CVE-2015-1333)

  - 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)

  - A flaw was found in the way the nft_flush_table()     function of the Linux kernel's netfilter tables     implementation flushed rules that were referencing     deleted chains. A local user who has the CAP_NET_ADMIN     capability could use this flaw to crash the     system.(CVE-2015-1573)

  - 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.

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 hid_input_field() function in     'drivers/hid/hid-core.c' in the Linux kernel before 4.6     allows physically proximate attackers to obtain     sensitive information from kernel memory or cause a     denial of service (out-of-bounds read) by connecting a     device.(CVE-2016-7915i1/4%0

  - The Linux kernel, before version 4.14.2, is vulnerable     to a deadlock caused by     fs/ocfs2/file.c:ocfs2_setattr(), as the function does     not wait for DIO requests before locking the inode.
    This can be exploited by local users to cause a     subsequent denial of service.(CVE-2017-18204i1/4%0

  - The vmw_gb_surface_define_ioctl function (accessible     via DRM_IOCTL_VMW_GB_SURFACE_CREATE) in     drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux     kernel through 4.11.4 defines a backup_handle variable     but does not give it an initial value. If one attempts     to create a GB surface, with a previously allocated DMA     buffer to be used as a backup buffer, the backup_handle     variable does not get written to and is then later     returned to user space, allowing local users to obtain     sensitive information from uninitialized kernel memory     via a crafted ioctl call.(CVE-2017-9605i1/4%0

  - Use-after-free vulnerability in the nfqnl_zcopy     function in net/netfilter/nfnetlink_queue_core.c in the     Linux kernel through 3.13.6 allows attackers to obtain     sensitive information from kernel memory by leveraging     the absence of a certain orphaning operation. NOTE: the     affected code was moved to the skb_zerocopy function in     net/core/skbuff.c before the vulnerability was     announced.(CVE-2014-2568i1/4%0

  - It was found that the Linux kernel's ISO file system     implementation did not correctly limit the traversal of     Rock Ridge extension Continuation Entries (CE). An     attacker with physical access to the system could use     this flaw to trigger an infinite loop in the kernel,     resulting in a denial of service.(CVE-2014-9420i1/4%0

  - An integer overflow vulnerability was found in the     ring_buffer_resize() calculations in which a privileged     user can adjust the size of the ringbuffer message     size. These calculations can create an issue where the     kernel memory allocator will not allocate the correct     count of pages yet expect them to be usable. This can     lead to the ftrace() output to appear to corrupt kernel     memory and possibly be used for privileged escalation     or more likely kernel panic.(CVE-2016-9754i1/4%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-2014-9730i1/4%0

  - In was found that in the Linux kernel, in     vmw_surface_define_ioctl() function in     'drivers/gpu/drm/vmwgfx/vmwgfx_surface.c' file, a     'num_sizes' parameter is assigned a user-controlled     value which is not checked if it is zero. This is used     in a call to kmalloc() and later leads to dereferencing     ZERO_SIZE_PTR, which in turn leads to a GPF and     possibly to a kernel panic.(CVE-2017-7261i1/4%0

  - A race condition flaw was found in the way the Linux     kernel keys management subsystem performed key garbage     collection. A local attacker could attempt accessing a     key while it was being garbage collected, which would     cause the system to crash.(CVE-2014-9529i1/4%0

  - A flaw was found in the Linux kernel's implementation     of i8042 serial ports. An attacker could cause a kernel     panic if they are able to add and remove devices as the     module is loaded.(CVE-2017-18079i1/4%0

  - drivers/hid/hid-pl.c in the Human Interface Device     (HID) subsystem in the Linux kernel through 3.11, when     CONFIG_HID_PANTHERLORD is enabled, allows physically     proximate attackers to cause a denial of service     (heap-based out-of-bounds write) via a crafted     device.(CVE-2013-2892i1/4%0

  - The __clear_user function in     arch/arm64/lib/clear_user.S in the Linux kernel before     3.17.4 on the ARM64 platform allows local users to     cause a denial of service (system crash) by reading one     byte beyond a /dev/zero page boundary.(CVE-2014-7843i1/4%0

  - A divide-by-zero vulnerability was found in a way the     kernel processes TCP connections. The error can occur     if a connection starts another cwnd reduction phase by     setting tp-i1/4zprior_cwnd to the current cwnd (0) in     tcp_init_cwnd_reduction(). A remote, unauthenticated     attacker could use this flaw to crash the kernel     (denial of service).(CVE-2016-2070i1/4%0

  - The adjust_branches function in kernel/bpf/verifier.c     in the Linux kernel before 4.5 does not consider the     delta in the backward-jump case, which allows local     users to obtain sensitive information from kernel     memory by creating a packet filter and then loading     crafted BPF instructions.(CVE-2016-2383i1/4%0

  - System using the infiniband support module ib_srpt were     vulnerable to a denial of service by system crash by a     local attacker who is able to abort writes to a device     using this initiator.(CVE-2016-6327i1/4%0

  - A security flaw was found in the Linux kernel in the     mark_source_chains() function in     'net/ipv4/netfilter/ip_tables.c'. It is possible for a     user-supplied 'ipt_entry' structure to have a large     'next_offset' field. This field is not bounds checked     prior to writing to a counter value at the supplied     offset.(CVE-2016-3134i1/4%0

  - An out-of-bounds access issue was discovered in     yurex_read() in drivers/usb/misc/yurex.c in the Linux     kernel. A local attacker could use user access     read/writes with incorrect bounds checking in the yurex     USB driver to crash the kernel or potentially escalate     privileges.(CVE-2018-16276i1/4%0

  - drivers/media/v4l2-core/videobuf2-v4l2.c in the Linux     kernel before 4.5.3 allows local users to cause a     denial of service (kernel memory write operation) or     possibly have unspecified other impact via a crafted     number of planes in a VIDIOC_DQBUF ioctl     call.(CVE-2016-4568i1/4%0

  - The usb_serial_console_disconnect function in     drivers/usb/serial/console.c in the Linux kernel,     before 4.13.8, allows local users to cause a denial of     service (use-after-free and system crash) or possibly     have unspecified other impact via a crafted USB device,     related to disconnection and failed     setup.(CVE-2017-16525i1/4%0

  - The Linux kernel is vulnerable to a NULL pointer     dereference in the ext4/xattr.c:ext4_xattr_inode_hash()     function. An attacker could trick a legitimate user or     a privileged attacker could exploit this to cause a     NULL pointer dereference with a crafted ext4 image.
    (CVE-2018-1094)

  - CVE-2015-8569: The (1) pptp_bind and (2) pptp_connect     functions in drivers/net/ppp/pptp.c in the Linux kernel     did not verify an address length, which allowed local     users to obtain sensitive information from kernel memory     and bypass the KASLR protection mechanism via a crafted     application (bnc#959190).

  - CVE-2015-8543: The networking implementation in the     Linux kernel did not validate protocol identifiers for     certain protocol families, which allowed local users to     cause a denial of service (NULL function pointer     dereference and system crash) or possibly gain     privileges by leveraging CLONE_NEWUSER support to     execute a crafted SOCK_RAW application (bnc#958886).

  - CVE-2014-8989: The Linux kernel did not properly     restrict dropping of supplemental group memberships in     certain namespace scenarios, which allowed local users     to bypass intended file permissions by leveraging a     POSIX ACL containing an entry for the group category     that is more restrictive than the entry for the other     category, aka a 'negative groups' issue, related to     kernel/groups.c, kernel/uid16.c, and     kernel/user_namespace.c (bnc#906545).

  - CVE-2015-5157: arch/x86/entry/entry_64.S in the Linux     kernel 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 (bnc#937969).

  - CVE-2015-7799: The slhc_init function in     drivers/net/slip/slhc.c in the Linux kernel through     4.2.3 did not ensure that certain slot numbers are     valid, which allowed local users to cause a denial of     service (NULL pointer dereference and system crash) via     a crafted PPPIOCSMAXCID ioctl call (bnc#949936).

  - CVE-2015-8104: The KVM subsystem in the Linux kernel     through 4.2.6, and Xen 4.3.x through 4.6.x, allowed     guest OS users to cause a denial of service (host OS     panic or hang) by triggering many #DB (aka Debug)     exceptions, related to svm.c (bnc#954404).

  - CVE-2015-5307: The KVM subsystem in the Linux kernel     through 4.2.6, and Xen 4.3.x through 4.6.x, allowed     guest OS users to cause a denial of service (host OS     panic or hang) by triggering many #AC (aka Alignment     Check) exceptions, related to svm.c and vmx.c     (bnc#953527).

  - CVE-2014-9529: Race condition in the key_gc_unused_keys     function in security/keys/gc.c in the Linux kernel     allowed local users to cause a denial of service (memory     corruption or panic) or possibly have unspecified other     impact via keyctl commands that trigger access to a key     structure member during garbage collection of a key     (bnc#912202).

  - CVE-2015-7990: Race condition in the rds_sendmsg     function in net/rds/sendmsg.c in the Linux kernel     allowed local users to cause a denial of service (NULL     pointer dereference and system crash) or possibly have     unspecified other impact by using a socket that was not     properly bound. NOTE: this vulnerability exists because     of an incomplete fix for CVE-2015-6937 (bnc#952384     953052).

  - CVE-2015-6937: The __rds_conn_create function in     net/rds/connection.c in the Linux kernel allowed local     users to cause a denial of service (NULL pointer     dereference and system crash) or possibly have     unspecified other impact by using a socket that was not     properly bound (bnc#945825).

  - CVE-2015-7885: The dgnc_mgmt_ioctl function in     drivers/staging/dgnc/dgnc_mgmt.c in the Linux kernel     through 4.3.3 did not initialize a certain structure     member, which allowed local users to obtain sensitive     information from kernel memory via a crafted application     (bnc#951627).

  - CVE-2015-8215: net/ipv6/addrconf.c in the IPv6 stack in     the Linux kernel did not validate attempted changes to     the MTU value, which allowed context-dependent attackers     to cause a denial of service (packet loss) via a value     that is (1) smaller than the minimum compliant value or     (2) larger than the MTU of an interface, as demonstrated     by a Router Advertisement (RA) message that is not     validated by a daemon, a different vulnerability than     CVE-2015-0272. NOTE: the scope of CVE-2015-0272 is     limited to the NetworkManager product (bnc#955354).

  - CVE-2015-8767: A case can occur when sctp_accept() is     called by the user during a heartbeat timeout event     after the 4-way handshake. Since sctp_assoc_migrate()     changes both assoc->base.sk and assoc->ep, the     bh_sock_lock in sctp_generate_heartbeat_event() will be     taken with the listening socket but released with the     new association socket. The result is a deadlock on any     future attempts to take the listening socket lock.
    (bsc#961509)

  - CVE-2015-8575: Validate socket address length in     sco_sock_bind() to prevent information leak     (bsc#959399).

The linux-2.6 update issued as DLA-246-1 caused regressions. This update corrects the defective patches applied in that update causing these problems. For reference the original advisory text follows.

This update fixes the CVEs described below.

CVE-2011-5321

Jiri Slaby discovered that tty_driver_lookup_tty() may leak a reference to the tty driver. A local user could use this flaw to crash the system.

CVE-2012-6689

Pablo Neira Ayuso discovered that non-root user-space processes can send forged Netlink notifications to other processes. A local user could use this flaw for denial of service or privilege escalation.

CVE-2014-3184

Ben Hawkes discovered that various HID drivers may over-read the report descriptor buffer, possibly resulting in a crash if a HID with a crafted descriptor is plugged in.

CVE-2014-8159

It was found that the Linux kernel's InfiniBand/RDMA subsystem did not properly sanitize input parameters while registering memory regions from user space via the (u)verbs API. A local user with access to a /dev/infiniband/uverbsX device could use this flaw to crash the system or, potentially, escalate their privileges on the system.

CVE-2014-9683

Dmitry Chernenkov discovered that eCryptfs writes past the end of the allocated buffer during encrypted filename decoding, resulting in local denial of service.

CVE-2014-9728 / CVE-2014-9729 / CVE-2014-9730 / CVE-2014-9731 / CVE-2015-4167

Carl Henrik Lunde discovered that the UDF implementation is missing several necessary length checks. A local user that can mount devices could use these various flaws to crash the system, to leak information from the kernel, or possibly for privilege escalation.

CVE-2015-1805

Red Hat discovered that the pipe iovec read and write implementations may iterate over the iovec twice but will modify the iovec such that the second iteration accesses the wrong memory. A local user could use this flaw to crash the system or possibly for privilege escalation.
This may also result in data corruption and information leaks in pipes between non-malicious processes.

CVE-2015-2041

Sasha Levin discovered that the LLC subsystem exposed some variables as sysctls with the wrong type. On a 64-bit kernel, this possibly allows privilege escalation from a process with CAP_NET_ADMIN capability; it also results in a trivial information leak.

CVE-2015-2042

Sasha Levin discovered that the RDS subsystem exposed some variables as sysctls with the wrong type. On a 64-bit kernel, this results in a trivial information leak.

CVE-2015-2830

Andrew Lutomirski discovered that when a 64-bit task on an amd64 kernel makes a fork(2) or clone(2) system call using int $0x80, the 32-bit compatibility flag is set (correctly) but is not cleared on return. As a result, both seccomp and audit will misinterpret the following system call by the task(s), possibly leading to a violation of security policy.

CVE-2015-2922

Modio AB discovered that the IPv6 subsystem would process a router advertisement that specifies no route but only a hop limit, which would then be applied to the interface that received it. This can result in loss of IPv6 connectivity beyond the local network.

This may be mitigated by disabling processing of IPv6 router advertisements if they are not needed: sysctl net.ipv6.conf.default.accept_ra=0 sysctl net.ipv6.conf.<interface>.accept_ra=0

CVE-2015-3339

It was found that the execve(2) system call can race with inode attribute changes made by chown(2). Although chown(2) clears the setuid/setgid bits of a file if it changes the respective owner ID, this race condition could result in execve(2) setting effective uid/gid to the new owner ID, a privilege escalation.

For the oldoldstable distribution (squeeze), these problems have been fixed in version 2.6.32-48squeeze12.

For the oldstable distribution (wheezy), these problems were fixed in linux version 3.2.68-1+deb7u1 or earlier, except for CVE-2015-1805 and CVE-2015-4167 which will be fixed soon.

For the stable distribution (jessie), these problems were fixed in linux version 3.16.7-ckt11-1 or earlier, except for CVE-2015-4167 which will be fixed later.

We recommend that you upgrade your linux-2.6 packages.
