  script_tag(name:"insight", value:"This update is based on upstream 4.4.39 and fixes at least the following
security issues:

Due to lack of size checking on ICMP header length, it is possible to
cause out-of-bounds read on stack (CVE-2016-8399)

The TCP stack in the Linux kernel before 4.8.10 mishandles skb
truncation, which allows local users to cause a denial of service
(system crash) via a crafted application that makes sendto system calls,
related to net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c (CVE-2016-8645).

The mpi_powm function in lib/mpi/mpi-pow.c in the Linux kernel through
4.8.11 does not ensure that memory is allocated for limb data, which
allows local users to cause a denial of service (stack memory corruption
and panic) via an add_key system call for an RSA key with a zero
exponent (CVE-2016-8650).

A race condition issue leading to a use-after-free flaw was found in the
way the raw packet sockets implementation in the Linux kernel networking
subsystem handled synchronization while creating the TPACKET_V3 ring
buffer. A local user able to open a raw packet socket (requires the
CAP_NET_RAW capability) could use this flaw to elevate their privileges
on the system (CVE-2016-8655).

A use-after-free vulnerability in the SCSI generic driver allows users
with write access to /dev/sg* or /dev/bsg* to elevate their privileges
(CVE-2016-9576).

Linux kernel built with the Kernel-based Virtual Machine(CONFIG_KVM)
support is vulnerable to an information leakage issue. It could occur
on x86 platform, while emulating instructions in 32bit mode. A
user/process could use this flaw to leak host kernel memory bytes
(CVE-2016-9756).

A bug in SO_{SND<pipe>RCV}BUFFORCE setsockopt() implementation allows
CAP_NET_ADMIN users to set negative sk_sndbuf or sk_rcvbuf values.
A user could use this flaw to cause various memory corruptions,
crashes and OOM (CVE-2016-9793).

A use-after-free vulnerability was found in ALSA pcm layer, which allows
local users to cause a denial of service, memory corruption, or possibly
other unspecified impact (CVE-2016-9794).

For other upstream fixes in this update, see the referenced changelogs.");
