An update that solves 20 vulnerabilities and has 11 security fixes can now be installed.
Description:
The SUSE Linux Enterprise 11 SP3 LTSS kernel was updated to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2018-1087: And an unprivileged KVM guest user could use this flaw to potentially escalate their privileges inside a guest. (bsc#1087088)
- CVE-2018-8897: An unprivileged system user could use incorrect set up interrupt stacks to crash the Linux kernel resulting in DoS issue. (bsc#1087088)
- CVE-2018-10124: The kill_something_info function in kernel/signal.c might allow local users to cause a denial of service via an INT_MIN argument (bnc#1089752).
- CVE-2018-10087: The kernel_wait4 function in kernel/exit.c might allow local users to cause a denial of service by triggering an attempted use of the -INT_MIN value (bnc#1089608).
- CVE-2018-7757: Memory leak in the sas_smp_get_phy_events function in drivers/scsi/libsas/sas_expander.c allowed local users to cause a denial of service (memory consumption) via many read accesses to files in the /sys/class/sas_phy directory, as demonstrated by the /sys/class/sas_phy/phy-1:0:12/invalid_dword_count file (bnc#1084536 1087209).
- CVE-2018-7566: A Buffer Overflow via an SNDRV_SEQ_IOCTL_SET_CLIENT_POOL ioctl write operation to /dev/snd/seq by a local user was fixed (bnc#1083483).
- CVE-2017-0861: Use-after-free vulnerability in the snd_pcm_info function in the ALSA subsystem allowed attackers to gain privileges via unspecified vectors (bnc#1088260).
- CVE-2018-8822: Incorrect buffer length handling in the ncp_read_kernel function in fs/ncpfs/ncplib_kernel.c could be exploited by malicious NCPFS servers to crash the kernel or execute code (bnc#1086162).
- CVE-2017-13166: An elevation of privilege vulnerability in the kernel v4l2 video driver. (bnc#1072865).
- CVE-2017-18203: The dm_get_from_kobject function in drivers/md/dm.c allow local users to cause a denial of service (BUG) by leveraging a race condition with __dm_destroy during creation and removal of DM devices (bnc#1083242).
- CVE-2017-16911: The vhci_hcd driver allowed allows local attackers to disclose kernel memory addresses. Successful exploitation requires that a USB device is attached over IP (bnc#1078674).
- CVE-2017-18208: The madvise_willneed function in mm/madvise.c allowed local users to cause a denial of service (infinite loop) by triggering use of MADVISE_WILLNEED for a DAX mapping (bnc#1083494).
- CVE-2017-16644: The hdpvr_probe function in drivers/media/usb/hdpvr/hdpvr-core.c allowed 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 (bnc#1067118).
- CVE-2018-6927: The futex_requeue function in kernel/futex.c might allow attackers to cause a denial of service (integer overflow) or possibly have unspecified other impact by triggering a negative wake or requeue value (bnc#1080757).
- CVE-2017-16914: The "stub_send_ret_submit()" function (drivers/usb/usbip/stub_tx.c) allowed attackers to cause a denial of service (NULL pointer dereference) via a specially crafted USB over IP packet (bnc#1078669).
- CVE-2016-7915: The hid_input_field function in drivers/hid/hid-core.c allowed physically proximate attackers to obtain sensitive information from kernel memory or cause a denial of service (out-of-bounds read) by connecting a device, as demonstrated by a Logitech DJ receiver (bnc#1010470).
- CVE-2015-5156: The virtnet_probe function in drivers/net/virtio_net.c attempted to support a FRAGLIST feature without proper memory allocation, which allowed guest OS users to cause a denial of service (buffer overflow and memory corruption) via a crafted sequence of fragmented packets (bnc#940776).
- CVE-2017-12190: The bio_map_user_iov and bio_unmap_user functions in block/bio.c did unbalanced refcounting when a SCSI I/O vector has small consecutive buffers belonging to the same page. The bio_add_pc_page function merges them into one, but the page reference is never dropped. This causes a memory leak and possible system lockup (exploitable against the host OS by a guest OS user, if a SCSI disk is passed through to a virtual machine) due to an out-of-memory condition (bnc#1062568).
- CVE-2017-16912: The "get_pipe()" function (drivers/usb/usbip/stub_rx.c) allowed attackers to cause a denial of service (out-of-bounds read) via a specially crafted USB over IP packet (bnc#1078673).
- CVE-2017-16913: The "stub_recv_cmd_submit()" function (drivers/usb/usbip/stub_rx.c) when handling CMD_SUBMIT packets allowed attackers to cause a denial of service (arbitrary memory allocation) via a specially crafted USB over IP packet (bnc#1078672).
The following non-security bugs were fixed:

- x86/kaiser: properly align trampoline stack (bsc#1087260).
- x86/retpoline: do not perform thunk calls in ring3 vsyscall code (bsc#1085331).
- xfs: check for buffer errors before waiting (bsc#1052943).
- xfs: fix allocbt cursor leak in xfs_alloc_ag_vextent_near (bsc#1087762).
