The openSUSE 13.2 kernel was updated to receive various security and
bugfixes.

Following security bugs were fixed:

  • CVE-2015-3290: A flaw was found in the way the Linux kernels nested NMI
    handler and espfix64 functionalities interacted during NMI processing. A
    local, unprivileged user could use this flaw to crash the system or,
    potentially, escalate their privileges on the system.
  • CVE-2015-3212: A race condition flaw was found in the way the Linux
    kernels SCTP implementation handled Address Configuration lists when
    performing Address Configuration Change (ASCONF). A local attacker could
    use this flaw to crash the system via a race condition triggered by
    setting certain ASCONF options on a socket.
  • CVE-2015-5364: A remote denial of service (hang) via UDP flood with
    incorrect package checksums was fixed. (bsc#936831).
  • CVE-2015-5366: A remote denial of service (unexpected error returns) via
    UDP flood with incorrect package checksums was fixed. (bsc#936831).
  • CVE-2015-4700: A local user could have created a bad instruction in the
    JIT processed BPF code, leading to a kernel crash (bnc#935705).
  • CVE-2015-1420: Race condition in the handle_to_path function in
    fs/fhandle.c in the Linux kernel 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 (bnc#915517).
  • CVE-2015-4692: The kvm_apic_has_events function in arch/x86/kvm/lapic.h
    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 leveraging /dev/kvm access for an ioctl call
    (bnc#935542).
  • CVE-2015-4167 CVE-2014-9728 CVE-2014-9730 CVE-2014-9729 CVE-2014-9731:
    Various problems in the UDF filesystem were fixed that could lead to
    crashes when mounting prepared udf filesystems.
  • CVE-2015-4002: drivers/staging/ozwpan/ozusbsvc1.c in the OZWPAN driver
    in the Linux kernel did not ensure that certain length values are
    sufficiently large, which allowed remote attackers to cause a denial of
    service (system crash or large loop) or possibly execute arbitrary code
    via a crafted packet, related to the (1) oz_usb_rx and (2)
    oz_usb_handle_ep_data functions (bnc#933934).
  • CVE-2015-4003: The oz_usb_handle_ep_data function in
    drivers/staging/ozwpan/ozusbsvc1.c in the OZWPAN driver in the Linux
    kernel allowed remote attackers to cause a denial of service
    (divide-by-zero error and system crash) via a crafted packet
    (bnc#933934).
  • CVE-2015-4001: Integer signedness error in the oz_hcd_get_desc_cnf
    function in drivers/staging/ozwpan/ozhcd.c in the OZWPAN driver in the
    Linux kernel allowed remote attackers to cause a denial of service
    (system crash) or possibly execute arbitrary code via a crafted packet
    (bnc#933934).
  • CVE-2015-4036: A potential memory corruption in vhost/scsi was fixed.
  • CVE-2015-2922: The ndisc_router_discovery function in net/ipv6/ndisc.c
    in the Neighbor Discovery (ND) protocol implementation in the IPv6 stack
    in the Linux kernel allowed remote attackers to reconfigure a hop-limit
    setting via a small hop_limit value in a Router Advertisement (RA)
    message (bnc#922583).
  • CVE-2015-3636: It was found that the Linux kernels ping socket
    implementation did not properly handle socket unhashing during spurious
    disconnects, which could lead to a use-after-free flaw. On x86-64
    architecture systems, a local user able to create ping sockets could use
    this flaw to crash the system. On non-x86-64 architecture systems, a
    local user able to create ping sockets could use this flaw to escalate
    their privileges on the system.
  • CVE-2015-2041: net/llc/sysctl_net_llc.c in the Linux kernel 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 (bnc#919007).
  • CVE-2015-3339: Race condition in the prepare_binprm function in
    fs/exec.c in the Linux kernel allowed local users to gain privileges by
    executing a setuid program at a time instant when a chown to root is in
    progress, and the ownership is changed but the setuid bit is not yet
    stripped.
  • CVE-2015-1465: The IPv4 implementation in the Linux kernel 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 (bnc#916225).
