SUSE-SU-2017:0229-1

This update for the Linux Kernel 3.12.67-606418 fixes several issues.

The following security bugs were fixed: - CVE-2016-9794: Race condition in the sndpcmperiodelapsed function in sound/core/pcmlib.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 SNDRVPCMTRIGGERSTART command (bsc#1013543). - CVE-2016-8632: The tipcmsgbuild function in net/tipc/msg.c in the Linux kernel did not validate the relationship between the minimum fragment length and the maximum packet size, which allowed local users to gain privileges or cause a denial of service (heap-based buffer overflow) by leveraging the CAPNETADMIN capability (bsc#1012852). - CVE-2016-9576: The blkrqmapuser_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).
