The tipc_nl_publ_dump function in net/tipc/socket.c in the Linux kernel through 4.6 does not verify socket existence, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a dumpit operation.

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 memory corruption flaw was found in the way the USB     ConnectTech WhiteHEAT serial driver processed     completion commands sent via USB Request Blocks     buffers. An attacker with physical access to the system     could use this flaw to crash the system or,     potentially, escalate their privileges on the     system.(CVE-2014-3185i1/4%0

  - Use-after-free vulnerability in the msm_set_crop     function in drivers/media/video/msm/msm_camera.c in the     MSM-Camera 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 (memory     corruption) via an application that makes a crafted     ioctl call.(CVE-2015-0568i1/4%0

  - The vivid_fb_ioctl function in     drivers/media/platform/vivid/vivid-osd.c in the Linux     kernel through 4.3.3 does not initialize a certain     structure member, which allows local users to obtain     sensitive information from kernel memory via a crafted     application.(CVE-2015-7884i1/4%0

  - The usb_get_bos_descriptor function in     drivers/usb/core/config.c in the Linux kernel can allow     a local users to cause a denial of service     (out-of-bounds read and system crash) or possibly have     unspecified other impact via a crafted USB     device.(CVE-2017-16535i1/4%0

  - The ACPI parsing functionality in the Linux kernel does     not flush the node and node_ext caches which causes a     kernel stack dump. This allows local users to obtain     sensitive information from kernel memory and use this     information to bypass the KASLR protection mechanism by     creating and applying crafted ACPI     table.(CVE-2017-13694i1/4%0

  - The is_ashmem_file function in     drivers/staging/android/ashmem.c in a certain Qualcomm     Innovation Center (QuIC) Android patch for the Linux     kernel 3.x mishandles pointer validation within the     KGSL Linux Graphics Module, which allows attackers to     bypass intended access restrictions by using the     /ashmem string as the dentry name.(CVE-2016-5340i1/4%0

  - It was found that the Linux kernel did not properly     account file descriptors passed over the unix socket     against the process limit. A local user could use this     flaw to exhaust all available memory on the     system.(CVE-2013-4312i1/4%0

  - Kernel memory corruption due to a buffer overflow was     found in brcmf_cfg80211_mgmt_tx() function in Linux     kernels from v3.9-rc1 to v4.13-rc1. The vulnerability     can be triggered by sending a crafted NL80211_CMD_FRAME     packet via netlink. This flaw is unlikely to be     triggered remotely as certain userspace code is needed     for this. 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 it is unlikely.(CVE-2017-7541i1/4%0

  - A flaw in the netback module allowed frontends to     control mapping of requests to request queues. An     attacker can change this mapping by requesting invalid     mapping requests allowing the (usually privileged)     backend to access out-of-bounds memory access for     reading and writing.(CVE-2018-15471i1/4%0

  - A buffer overflow vulnerability due to a lack of input     filtering of incoming fragmented datagrams was found in     the IP-over-1394 driver firewire-net in a fragment     handling code in the Linux kernel. The vulnerability     exists since firewire supported IPv4, i.e. since     version 2.6.31 (year 2009) till version v4.9-rc4. A     maliciously formed fragment with a respectively large     datagram offset would cause a memcpy() past the     datagram buffer, which would cause a system panic or     possible arbitrary code execution.The flaw requires     firewire-net module to be loaded and is remotely     exploitable from connected firewire devices, but not     over a local network.(CVE-2016-8633i1/4%0

  - It was found that the Linux kernel can hit a BUG_ON()     statement in the __xfs_get_blocks() in the     fs/xfs/xfs_aops.c because of a race condition between     direct and memory-mapped I/O associated with a hole in     a file that is handled with BUG_ON() instead of an I/O     failure. This allows a local unprivileged attacker to     cause a system crash and a denial of     service.(CVE-2016-10741i1/4%0

  - A vulnerability was found in the Linux kernel. The     pointer to the netlink socket attribute is not checked,     which could cause a null pointer dereference when     parsing the nested attributes in function     tipc_nl_publ_dump(). This allows local users to cause a     DoS.(CVE-2016-4951i1/4%0

  - It was reported that with Linux kernel, earlier than     version v4.10-rc8, an application may trigger a BUG_ON     in sctp_wait_for_sndbuf if the socket tx buffer is     full, a thread is waiting on it to queue more data, and     meanwhile another thread peels off the association     being used by the first thread.(CVE-2017-5986i1/4%0

  - The kvm_vm_ioctl_check_extension function in     arch/powerpc/kvm/powerpc.c in the Linux kernel before     4.13.11 allows local users to cause a denial of service     (NULL pointer dereference and system crash) via a     KVM_CHECK_EXTENSION KVM_CAP_PPC_HTM ioctl call to     /dev/kvm.(CVE-2017-15306i1/4%0

  - A flaw was found in the way the Linux kernel's 32-bit     emulation implementation handled forking or closing of     a task with an 'int80' entry. A local user could     potentially use this flaw to escalate their privileges     on the system.(CVE-2015-2830i1/4%0

  - A flaw was found in the way the Linux kernel's SCTP     implementation validated INIT chunks when performing     Address Configuration Change (ASCONF). A remote     attacker could use this flaw to crash the system by     sending a specially crafted SCTP packet to trigger a     NULL pointer dereference on the     system.(CVE-2014-7841i1/4%0

  - A race condition issue leading to a use-after-free flaw     was found in the way the raw packet sockets are     implemented in the Linux kernel networking subsystem     handling synchronization. A local user able to open a     raw packet socket (requires the CAP_NET_RAW capability)     can use this issue to crash the     system.(CVE-2017-1000111)

  - A flaw was found in the way the Linux kernel performed     forking inside of a transaction. A local, unprivileged     user on a PowerPC system that supports transactional     memory could use this flaw to crash the     system.(CVE-2014-2673i1/4%0

  - The hashbin_delete function in net/irda/irqueue.c in     the Linux kernel improperly manages lock dropping,     which allows local users to cause a denial of service     (deadlock) via crafted operations on IrDA     devices.(CVE-2017-6348i1/4%0

  - An out-of-bounds flaw was found in the kernel, where     the length of the sockaddr parameter was not checked in     the pptp_bind() and pptp_connect() functions. As a     result, more kernel memory was copied out than     required, leaking information from the kernel stack     (including kernel addresses). A local system user could     exploit this flaw to bypass kernel ASLR or leak other     information.(CVE-2015-8569i1/4%0

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

A flaw was discovered in processing setsockopt for 32 bit processes on 64 bit systems. This flaw will allow attackers to alter arbitary kernel memory when unloading a kernel module. This action is usually restricted to root-priveledged users but can also be leveraged if the kernel is compiled with CONFIG_USER_NS and CONFIG_NET_NS.
(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 vulnerability was found in the Linux kernel. The pointer to the netlink socket attribute is not checked, which could cause a NULL pointer dereference when parsing the nested attributes in function tipc_nl_publ_dump().

This allows local users to cause a DoS. (CVE-2016-4951)

A double free vulnerability was found in netlink_dump, which could cause a denial of service or possibly other unspecified impact.
(CVE-2016-9806)

(Updated on 2016-07-14: CVE-2016-4998 and CVE-2016-4951 were fixed in this version, but was not previously listed in this errata.)

(Updated on 2017-01-19: CVE-2016-9806 was fixed in this release but was previously not part of this errata.)

The openSUSE Leap 42.1 kernel was updated to 4.1.26 to receive various security and bugfixes.

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.
    (bsc#983213).

  - CVE-2016-4580: The x25_negotiate_facilities function in     net/x25/x25_facilities.c in the Linux kernel did not     properly initialize a certain data structure, which     allowed attackers to obtain sensitive information from     kernel stack memory via an X.25 Call Request.
    (bsc#981267).

  - CVE-2016-0758: Tags with indefinite length could have     corrupted pointers in asn1_find_indefinite_length     (bsc#979867).

  - 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).

  - CVE-2016-4485: A kernel information leak in llc was     fixed (bsc#978821).

  - CVE-2016-4486: A kernel information leak in rtnetlink     was fixed, where 4 uninitialized bytes could leak to     userspace (bsc#978822).

  - CVE-2016-4557: A use-after-free via double-fdput in     replace_map_fd_with_map_ptr() was fixed, which could     allow privilege escalation (bsc#979018).

  - CVE-2016-4565: When the 'rdma_ucm' infiniband module is     loaded, local attackers could escalate their privileges     (bsc#979548).

  - CVE-2016-4569: A kernel information leak in the ALSA     timer via events via snd_timer_user_tinterrupt that     could leak information to userspace was fixed     (bsc#979213).

  - CVE-2016-4578: A kernel information leak in the ALSA     timer via events that could leak information to     userspace was fixed (bsc#979879).
