    An update that fixes three vulnerabilities is now available.

    Description:

    This update for the Linux Kernel 3.12.49-11 fixes several issues.

    The following security bugs were fixed:
    - CVE-2016-6480: Race condition in the ioctl_send_fib function in
    drivers/scsi/aacraid/commctrl.c in the Linux kernel allowed local users
    to cause a denial of service (out-of-bounds access or system crash) by
    changing a certain size value, aka a "double fetch" vulnerability
    (bsc#991667).
    - CVE-2016-5829: Multiple heap-based buffer overflows in the
    hiddev_ioctl_usage function in drivers/hid/usbhid/hiddev.c in the Linux
    kernel allowed local users to cause a denial of service or possibly have
    unspecified other impact via a crafted (1) HIDIOCGUSAGES or (2)
    HIDIOCSUSAGES ioctl call (bsc#986573).
    - CVE-2016-4997: The compat IPT_SO_SET_REPLACE setsockopt implementation
    in the netfilter subsystem in the Linux kernel allowed local users to
    gain privileges or cause a denial of service (memory corruption) by
    leveraging in-container root access to provide a crafted offset value
    that triggers an unintended decrement (bsc#986377).
