|References:||#1012852 #1013543 #1013604 #1014271 #1017589|
An update that solves four vulnerabilities and has one errata is now available.
This update for the Linux Kernel 3.12.53-60_30 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
- 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).
