   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).
