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

  - A vulnerability was found in Linux kernel. There is an     information leak in file 'sound/core/timer.c' of the     latest mainline Linux kernel, the stack object     aEURoetreadaEUR has a total size of 32 bytes. It contains a     8-bytes padding, which is not initialized but sent to     user via copy_to_user(), resulting a kernel     leak.(CVE-2016-4569)

  - A vulnerability was found in Linux kernel. There is an     information leak in file sound/core/timer.c of the     latest mainline Linux kernel. The stack object aEURoer1aEUR     has a total size of 32 bytes. Its field aEURoeeventaEUR and     aEURoevalaEUR both contain 4 bytes padding. These 8 bytes     padding bytes are sent to user without being     initialized.(CVE-2016-4578)

  - The x25_negotiate_facilities function in     net/x25/x25_facilities.c in the Linux kernel before     4.5.5 does not properly initialize a certain data     structure, which allows attackers to obtain sensitive     information from kernel stack memory via an X.25 Call     Request.(CVE-2016-4580)

  - fs/pnode.c in the Linux kernel before 4.5.4 does not     properly traverse a mount propagation tree in a certain     case involving a slave mount, which allows local users     to cause a denial of service (NULL pointer dereference     and OOPS) via a crafted series of mount system     calls.(CVE-2016-4581)

  - Use after free vulnerability was found in percpu using     previously allocated memory in bpf. First
    __alloc_percpu_gfp() is called, then the memory is     freed with free_percpu() which triggers async     pcpu_balance_work and then pcpu_extend_area_map could     use a chunk after it has been freed.(CVE-2016-4794)

  - Use-after-free vulnerability in     drivers/net/ppp/ppp_generic.c in the Linux kernel     before 4.5.2 allows local users to cause a denial of     service (memory corruption and system crash, or     spinlock) or possibly have unspecified other impact by     removing a network namespace, related to the     ppp_register_net_channel and ppp_unregister_channel     functions.(CVE-2016-4805)

  - A vulnerability was found in the Linux kernel. Payloads     of NM entries are not supposed to contain NUL. When     such entry is processed, only the part prior to the     first NUL goes into the concatenation (i.e. the     directory entry name being encoded by a bunch of NM     entries). The process stops when the amount collected     so far + the claimed amount in the current NM entry     exceed 254. However, the value returned as the total     length is the sum of *claimed* sizes, not the actual     amount collected. And that's what will be passed to     readdir() callback as the name length - 8Kb
    __copy_to_user() from a buffer allocated by
    __get_free_page().(CVE-2016-4913)

  - A flaw was discovered in processing setsockopt for 32     bit processes on 64 bit systems. This flaw will allow     attackers to alter arbitrary kernel memory when     unloading a kernel module. This action is usually     restricted to root-privileged users but can also be     leveraged if the kernel is compiled with CONFIG_USER_NS     and CONFIG_NET_NS and the user is granted elevated     privileges.(CVE-2016-4997)

  - An out-of-bounds heap memory access leading to a Denial     of Service, heap disclosure, or further impact was     found in setsockopt(). The function call is normally     restricted to root, however some processes with     cap_sys_admin may also be able to trigger this flaw in     privileged container environments.(CVE-2016-4998)

  - A race condition was found in the way the Linux     kernel's memory subsystem handled the copy-on-write     (COW) breakage of private read-only memory mappings. An     unprivileged, local user could use this flaw to gain     write access to otherwise read-only memory mappings and     thus increase their privileges on the     system.(CVE-2016-5195)

  - It was found that the RFC 5961 challenge ACK rate     limiting as implemented in the Linux kernel's     networking subsystem allowed an off-path attacker to     leak certain information about a given connection by     creating congestion on the global challenge ACK rate     limit counter and then measuring the changes by probing     packets. An off-path attacker could use this flaw to     either terminate TCP connection and/or inject payload     into non-secured TCP connection between two endpoints     on the network.(CVE-2016-5696)

  - A heap-based buffer overflow vulnerability was found in     the Linux kernel's hiddev driver. This flaw could allow     a local attacker to corrupt kernel memory, possible     privilege escalation or crashing the     system.(CVE-2016-5829)

  - When creating audit records for parameters to executed     children processes, an attacker can convince the Linux     kernel audit subsystem can create corrupt records which     may allow an attacker to misrepresent or evade logging     of executing commands.(CVE-2016-6136)

  - It was found that the unlink and rename functionality     in overlayfs did not verify the upper dentry for     staleness. A local, unprivileged user could use the     rename syscall on overlayfs on top of xfs to panic or     crash the system.(CVE-2016-6197)

  - A flaw was found that the vfs_rename() function did not     detect hard links on overlayfs. A local, unprivileged     user could use the rename syscall on overlayfs on top     of xfs to crash the system.(CVE-2016-6198)

  - 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-2016-6327)

  - A race condition flaw was found in the ioctl_send_fib()     function in the Linux kernel's aacraid implementation.
    A local attacker could use this flaw to cause a denial     of service (out-of-bounds access or system crash) by     changing a certain size value.(CVE-2016-6480)

  - kernel/events/core.c in the performance subsystem in     the Linux kernel before 4.0 mismanages locks during     certain migrations, which allows local users to gain     privileges via a crafted application, aka Android     internal bug 30955111.(CVE-2016-6786)

  - kernel/events/core.c in the performance subsystem in     the Linux kernel before 4.0 mismanages locks during     certain migrations, which allows local users to gain     privileges via a crafted application, aka Android     internal bug 31095224.(CVE-2016-6787)

  - 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)

  - Linux kernel built with the 802.1Q/802.1ad     VLAN(CONFIG_VLAN_8021Q) OR Virtual eXtensible Local     Area Network(CONFIG_VXLAN) with Transparent Ethernet     Bridging(TEB) GRO support, is vulnerable to a stack     overflow issue. It could occur while receiving large     packets via GRO path, as an unlimited recursion could     unfold in both VLAN and TEB modules, leading to a stack     corruption in the kernel.(CVE-2016-7039)

  - 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)

  - It was found that when file permissions were modified     via chmod and the user modifying them was not in the     owning group or capable of CAP_FSETID, the setgid bit     would be cleared. Setting a POSIX ACL via setxattr sets     the file permissions as well as the new ACL, but     doesn't clear the setgid bit in a similar way. This     could allow a local user to gain group privileges via     certain setgid applications.(CVE-2016-7097)

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 :

A     privileged guest user could use this flaw to crash the     host kernel resulting in denial of     service.(CVE-2017-12168i1/4%0

  - The iscsi_if_rx() function in     'drivers/scsi/scsi_transport_iscsi.c' in the Linux     kernel from v2.6.24-rc1 through 4.13.2 allows local     users to cause a denial of service (a system panic) by     making a number of certain syscalls by leveraging     incorrect length validation in the kernel     code.(CVE-2017-14489i1/4%0

  - The hdpvr_probe function in     drivers/media/usb/hdpvr/hdpvr-core.c in the Linux     kernel through 4.13.11 allows local users to cause a     denial of service (improper error handling and system     crash) or possibly have unspecified other impact via a     crafted USB device.(CVE-2017-16644i1/4%0

  - The dvb frontend management subsystem in the Linux     kernel contains a use-after-free which can allow a     malicious user to write to memory that may be assigned     to another kernel structure. This could create memory     corruption, panic, or possibly other side     affects.(CVE-2017-16648i1/4%0

  - It was found that the Linux kernel's IPv6     implementation mishandled socket options. A local     attacker could abuse concurrent access to the socket     options to escalate their privileges, or cause a denial     of service (use-after-free and system crash) via a     crafted sendmsg system call.(CVE-2016-3841i1/4%0

  - A flaw was found in the Linux kernel's ext4 filesystem.
    A local user can cause a use-after-free in     ext4_xattr_set_entry function and a denial of service     or unspecified other impact may occur by renaming a     file in a crafted ext4 filesystem     image.(CVE-2018-10879i1/4%0

  - A race condition was found in the Linux kernel, present     since v3.14-rc1 through v4.12. The race happens between     threads of inotify_handle_event() and vfs_rename()     while running the rename operation against the same     file. As a result of the race the next slab data or the     slab's free list pointer can be corrupted with     attacker-controlled data, which may lead to the     privilege escalation.(CVE-2017-7533i1/4%0

  - A privilege-escalation vulnerability was discovered in     the Linux kernel built with User Namespace     (CONFIG_USER_NS) support. The flaw occurred when the     ptrace() system call was used on a root-owned process     to enter a user namespace. A privileged namespace user     could exploit this flaw to potentially escalate their     privileges on the system, outside the original     namespace.(CVE-2015-8709i1/4%0

  - Use-after-free vulnerability in     drivers/net/ppp/ppp_generic.c in the Linux kernel     before 4.5.2 allows local users to cause a denial of     service (memory corruption and system crash, or     spinlock) or possibly have unspecified other impact by     removing a network namespace, related to the     ppp_register_net_channel and ppp_unregister_channel     functions.(CVE-2016-4805i1/4%0

  - A flaw was found in the way the Linux kernel's     kvm_iommu_map_pages() function handled IOMMU mapping     failures. A privileged user in a guest with an assigned     host device could use this flaw to crash the     host.(CVE-2014-3601i1/4%0

  - A flaw was found in the Linux kernel's implementation     of associative arrays introduced in 3.13. This     functionality was backported to the 3.10 kernels in Red     Hat Enterprise Linux 7. The flaw involved a null     pointer dereference in assoc_array_apply_edit() due to     incorrect node-splitting in assoc_array implementation.
    This affects the keyring key type and thus key addition     and link creation operations may cause the kernel to     panic.(CVE-2017-12193i1/4%0

  - Multiple race conditions in drivers/char/adsprpc.c and     drivers/char/adsprpc_compat.c in the ADSPRPC driver for     the Linux kernel 3.x, as used in Qualcomm Innovation     Center (QuIC) Android contributions for MSM devices and     other products, allow attackers to cause a denial of     service (zero-value write) or possibly have unspecified     other impact via a COMPAT_FASTRPC_IOCTL_INVOKE_FD ioctl     call.(CVE-2015-0572i1/4%0

  - The sanity_check_ckpt function in fs/f2fs/super.c in     the Linux kernel before version 4.12.4 does not     validate the blkoff and segno arrays. This allows an     unprivileged, local user to cause a system panic and     DoS. Due to the nature of the flaw, privilege     escalation cannot be fully ruled out, although we     believe it is unlikely.(CVE-2017-10663i1/4%0

  - A stack overflow flaw caused by infinite recursion was     found in the way the Linux kernel's Universal Disk     Format (UDF) file system implementation processed     indirect Information Control Blocks (ICBs). An attacker     with physical access to the system could use a     specially crafted UDF image to crash the     system.(CVE-2014-6410i1/4%0

  - Race condition in the ion_ioctl function in     drivers/staging/android/ion/ion.c in the Linux kernel     before 4.6 allows local users to gain privileges or     cause a denial of service (use-after-free) by calling     ION_IOC_FREE on two CPUs at the same     time.(CVE-2016-9120i1/4%0

  - drivers/hid/hid-picolcd_core.c in the Human Interface     Device (HID) subsystem in the Linux kernel through     3.11, when CONFIG_HID_PICOLCD is enabled, allows     physically proximate attackers to cause a denial of     service (NULL pointer dereference and OOPS) via a     crafted device.(CVE-2013-2899i1/4%0

  - A flaw was found in the Linux kernel's implementation     of overlayfs. An attacker can leak file resources in     the system by opening a large file with write     permissions on a overlay filesystem that is     insufficient to deal with the size of the write.When     unmounting the underlying device, the system is unable     to free an inode and this will consume resources.
    Repeating this for all available inodes and memory will     create a denial of service situation.(CVE-2015-8953i1/4%0

  - Buffer overflow in the mp_override_legacy_irq()     function in arch/x86/kernel/acpi/boot.c in the Linux     kernel through 4.12.2 allows local users to gain     privileges via a crafted ACPI table.(CVE-2017-11473i1/4%0

  - CVE-2016-1583     Jann Horn of Google Project Zero reported that the     eCryptfs filesystem could be used together with the proc     filesystem to cause a kernel stack overflow. If the     ecryptfs-utils package is installed, local users could     exploit this, via the mount.ecryptfs_private program,     for denial of service (crash) or possibly for privilege     escalation.

  - CVE-2016-2117     Justin Yackoski of Cryptonite discovered that the     Atheros L2 ethernet driver incorrectly enables     scatter/gather I/O. A remote attacker could take     advantage of this flaw to obtain potentially sensitive     information from kernel memory.

  - CVE-2016-2143     Marcin Koscielnicki discovered that the fork     implementation in the Linux kernel on s390 platforms     mishandles the case of four page-table levels, which     allows local users to cause a denial of service (system     crash).

  - CVE-2016-3070     Jan Stancek of Red Hat discovered a local denial of     service vulnerability in AIO handling.

  - CVE-2016-3134     The Google Project Zero team found that the netfilter     subsystem does not sufficiently validate filter table     entries. A user with the CAP_NET_ADMIN capability could     use this for denial of service (crash) or possibly for     privilege escalation. Debian disables unprivileged user     namespaces by default, if locally enabled with the     kernel.unprivileged_userns_clone sysctl, this allows     privilege escalation.

  - CVE-2016-3156     Solar Designer discovered that the IPv4 implementation     in the Linux kernel did not perform the destruction of     inet device objects properly. An attacker in a guest OS     could use this to cause a denial of service (networking     outage) in the host OS.

  - CVE-2016-3157 / XSA-171     Andy Lutomirski discovered that the x86_64 (amd64) task     switching implementation did not correctly update the     I/O permission level when running as a Xen paravirtual     (PV) guest. In some configurations this would allow     local users to cause a denial of service (crash) or to     escalate their privileges within the guest.

  - CVE-2016-3672     Hector Marco and Ismael Ripoll noted that it was     possible to disable Address Space Layout Randomisation     (ASLR) for x86_32 (i386) programs by removing the stack     resource limit. This made it easier for local users to     exploit security flaws in programs that have the setuid     or setgid flag set.

  - CVE-2016-3951     It was discovered that the cdc_ncm driver would free     memory prematurely if certain errors occurred during its     initialisation. This allowed a physically present user     with a specially designed USB device to cause a denial     of service (crash) or possibly to escalate their     privileges.

  - CVE-2016-3955     Ignat Korchagin reported that the usbip subsystem did     not check the length of data received for a USB buffer.
    This allowed denial of service (crash) or privilege     escalation on a system configured as a usbip client, by     the usbip server or by an attacker able to impersonate     it over the network. A system configured as a usbip     server might be similarly vulnerable to physically     present users.

  - CVE-2016-3961 / XSA-174     Vitaly Kuznetsov of Red Hat discovered that Linux     allowed the use of hugetlbfs on x86 (i386 and amd64)     systems even when running as a Xen paravirtualised (PV)     guest, although Xen does not support huge pages. This     allowed users with access to /dev/hugepages to cause a     denial of service (crash) in the guest.

  - CVE-2016-4470     David Howells of Red Hat discovered that a local user     can trigger a flaw in the Linux kernel's handling of key     lookups in the keychain subsystem, leading to a denial     of service (crash) or possibly to privilege escalation.

  - CVE-2016-4482, CVE-2016-4485, CVE-2016-4486,     CVE-2016-4569, CVE-2016-4578, CVE-2016-4580,     CVE-2016-5243, CVE-2016-5244

    Kangjie Lu reported that the USB devio, llc, rtnetlink,     ALSA timer, x25, tipc, and rds facilities leaked     information from the kernel stack.

  - CVE-2016-4565     Jann Horn of Google Project Zero reported that various     components in the InfiniBand stack implemented unusual     semantics for the write() operation. On a system with     InfiniBand drivers loaded, local users could use this     for denial of service or privilege escalation.

  - CVE-2016-4581     Tycho Andersen discovered that in some situations the     Linux kernel did not handle propagated mounts correctly.
    A local user can take advantage of this flaw to cause a     denial of service (system crash).

  - CVE-2016-4805     Baozeng Ding discovered a use-after-free in the generic     PPP layer in the Linux kernel. A local user can take     advantage of this flaw to cause a denial of service     (system crash), or potentially escalate their     privileges.

  - CVE-2016-4913     Al Viro found that the ISO9660 filesystem implementation     did not correctly count the length of certain invalid     name entries. Reading a directory containing such name     entries would leak information from kernel memory. Users     permitted to mount disks or disk images could use this     to obtain sensitive information.

  - CVE-2016-4997 / CVE-2016-4998     Jesse Hertz and Tim Newsham discovered that missing     input sanitising in Netfilter socket handling may result     in denial of service. Debian disables unprivileged user     namespaces by default, if locally enabled with the     kernel.unprivileged_userns_clone sysctl, this also     allows privilege escalation.

Andrey Konovalov discovered that the CDC Network Control Model USB driver in the Linux kernel did not cancel work events queued if a later error occurred, resulting in a use-after-free. An attacker with physical access could use this to cause a denial of service (system crash). (CVE-2016-3951)

Kangjie Lu discovered an information leak in the core USB implementation in the Linux kernel. A local attacker could use this to obtain potentially sensitive information from kernel memory.
(CVE-2016-4482)

Kangjie Lu discovered an information leak in the timer handling implementation in the Advanced Linux Sound Architecture (ALSA) subsystem of the Linux kernel. A local attacker could use this to obtain potentially sensitive information from kernel memory.
(CVE-2016-4569, CVE-2016-4578)

Kangjie Lu discovered an information leak in the X.25 Call Request handling in the Linux kernel. A local attacker could use this to obtain potentially sensitive information from kernel memory.
(CVE-2016-4580)

Baozeng Ding discovered a use-after-free issue in the generic PPP layer in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-4805)

It was discovered that an information leak exists in the Rock Ridge implementation in the Linux kernel. A local attacker who is able to mount a malicious iso9660 file system image could exploit this flaw to obtain potentially sensitive information from kernel memory.
(CVE-2016-4913).

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.

The following security bugs were fixed :

  - CVE-2016-1583: Prevent the usage of mmap when the lower     file system does not allow it. This could have lead to     local privilege escalation when ecryptfs-utils was     installed and /sbin/mount.ecryptfs_private was setuid     (bsc#983143).

  - CVE-2016-4565: The InfiniBand (aka IB) stack in the     Linux kernel incorrectly relies on the write system     call, which allows local users to cause a denial of     service (kernel memory write operation) or possibly have     unspecified other impact via a uAPI interface.
    (bsc#979548)

  - CVE-2016-4805: Use-after-free vulnerability in     drivers/net/ppp/ppp_generic.c in the Linux kernel     allowed local users to cause a denial of service (memory     corruption and system crash, or spinlock) or possibly     have unspecified other impact by removing a network     namespace, related to the ppp_register_net_channel and     ppp_unregister_channel functions. (bsc#980371).

  - CVE-2016-4951: The tipc_nl_publ_dump function in     net/tipc/socket.c in the Linux kernel did not verify     socket existence, which allowed local users to cause a     denial of service (NULL pointer dereference and system     crash) or possibly have unspecified other impact via a     dumpit operation. (bsc#981058).

  - CVE-2016-5244: An information leak vulnerability in     function rds_inc_info_copy of file net/rds/recv.c was     fixed that might have leaked kernel stack data.

  - CVE-2016-2053: The asn1_ber_decoder function in     lib/asn1_decoder.c in the Linux kernel allowed attackers     to cause a denial of service (panic) via an ASN.1 BER     file that lacks a public key, leading to mishandling by     the public_key_verify_signature function in     crypto/asymmetric_keys/public_key.c (bnc#963762).

  - CVE-2013-7446: Use-after-free vulnerability in     net/unix/af_unix.c in the Linux kernel allowed local     users to bypass intended AF_UNIX socket permissions or     cause a denial of service (panic) via crafted epoll_ctl     calls (bnc#955654).

  - CVE-2016-3134: The netfilter subsystem in the Linux     kernel did not validate certain offset fields, which     allowed local users to gain privileges or cause a denial     of service (heap memory corruption) via an     IPT_SO_SET_REPLACE setsockopt call (bnc#971126).

  - CVE-2016-3672: The arch_pick_mmap_layout function in     arch/x86/mm/mmap.c in the Linux kernel did not properly     randomize the legacy base address, which made it easier     for local users to defeat the intended restrictions on     the ADDR_NO_RANDOMIZE flag, and bypass the ASLR     protection mechanism for a setuid or setgid program, by     disabling stack-consumption resource limits     (bnc#974308).

  - CVE-2016-4482: A kernel information leak in the usbfs     devio connectinfo was fixed, which could expose kernel     stack memory to userspace. (bnc#978401).
