SUSE Security Update: Security update for Linux Kernel Live Patch 0 for SLE 12 SP2
______________________________________________________________________________

Announcement ID: SUSE-SU-2017:0227-1
Rating: important
References: #1012852 #1013543 #1014271 #1019079

______________________________________________________________________________

An update that fixes four vulnerabilities is now available.

Description:

This update for the Linux Kernel 4.4.21-69 fixes several issues.

The following security bugs were fixed:
– CVE-2016-10088: The sg implementation in the Linux kernel did not
properly restrict write operations in situations where the KERNEL_DS
option is set, 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, related to block/bsg.c and
drivers/scsi/sg.c. NOTE: this vulnerability exists because of an
incomplete fix for CVE-2016-9576 (bsc#1019079).
– 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-2016-8632: The tipc_msg_build 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 CAP_NET_ADMIN capability (bsc#1012852).
– 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). before 4.8.14

net/netlink/af_netlink.c in the Linux kernel allowed local users to
cause a denial of service (double free) or possibly have unspecified

______________________________________________________________________________

An update that solves two vulnerabilities and has one

errata is now available.

Description:

This update for the Linux Kernel 3.12.67-60_64_21 fixes several issues.

The following security bugs were fixed:

- 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).

Patch Instructions:

To install this SUSE Security Update use YaST online_update.

Alternatively you can run the command listed for your product:

- SUSE Linux Enterprise Live Patching 12:
