   An update that solves three vulnerabilities and has one
   errata is now available.

Description:

   This update for the Linux Kernel 3.12.60-52_60 fixes several issues.

   The following security bugs were fixed:
   - CVE-2016-9806: Race condition in the netlink_dump function in
     net/netlink/af_netlink.c in the Linux kernel allowed local users to
     cause a denial of service (double free) or possibly have unspecified
     other impact via a crafted application that made sendmsg system calls,
     leading to a free operation associated with a new dump that started
     earlier than anticipated (bsc#1017589).
   - CVE-2016-9794: Race condition in the snd_pcm_period_elapsed function in
     sound/core/pcm_lib.c in the ALSA subsystem in the Linux kernel allowed
     local users to cause a denial of service (use-after-free) or possibly
     have unspecified other impact via a crafted SNDRV_PCM_TRIGGER_START
     command (bsc#1013543).
   - CVE-2016-9576: The blk_rq_map_user_iov function in block/blk-map.c in
     the Linux kernel did not properly restrict the type of iterator, which
     allowed local users to read or write to arbitrary kernel memory
     locations or cause a denial of service (use-after-free) by leveraging
     access to a /dev/sg device (bsc#1014271).
