______________________________________________________________________________

 

An update that solves 11 vulnerabilities and has 49 fixes

is now available.

 

Description:

 

The SUSE Linux Enterprise 11 SP4 RT kernel was updated to receive various

security and bugfixes.

 

This feature was added:

 

- Support for the 2017 Intel Purley platform.

 

The following security bugs were fixed:

 

- CVE-2016-5195: A local privilege escalation using MAP_PRIVATE was fixed,

which is reportedly exploited in the wild (bsc#1004418).

- CVE-2016-0823: The pagemap_open function in fs/proc/task_mmu.c in the

Linux kernel allowed local users to obtain sensitive physical-address

information by reading a pagemap file, aka Android internal bug 25739721

(bnc#994759).

- CVE-2016-3841: The IPv6 stack in the Linux kernel mishandled options

data, which allowed local users to gain privileges or cause a denial of

service (use-after-free and system crash) via a crafted sendmsg system

call (bnc#992566).

- CVE-2016-6828: Use after free in tcp_xmit_retransmit_queue or other tcp_

functions (bsc#994296)

- CVE-2016-5696: net/ipv4/tcp_input.c in the Linux kernel did not properly

determine the rate of challenge ACK segments, which made it easier for

man-in-the-middle attackers to hijack TCP sessions via a blind in-window

attack (bnc#989152)

- CVE-2016-6480: Race condition in the ioctl_send_fib function in

drivers/scsi/aacraid/commctrl.c in the Linux kernel allowed local users

to cause a denial of service (out-of-bounds access or system crash) by

changing a certain size value, aka a "double fetch" vulnerability

(bnc#991608)

- CVE-2016-4997: The compat IPT_SO_SET_REPLACE and IP6T_SO_SET_REPLACE

setsockopt implementations in the netfilter subsystem in the Linux

kernel allowed local users to gain privileges or cause a denial of

service (memory corruption) by leveraging in-container root access to

provide a crafted offset value that triggers an unintended decrement

(bnc#986362).

- CVE-2015-7513: arch/x86/kvm/x86.c in the Linux kernel did not reset the

PIT counter values during state restoration, which allowed guest OS

users to cause a denial of service (divide-by-zero error and host OS

crash) via a zero value, related to the kvm_vm_ioctl_set_pit and

kvm_vm_ioctl_set_pit2 functions (bnc#960689).

- CVE-2013-4312: The Linux kernel allowed local users to bypass

file-descriptor limits and cause a denial of service (memory

consumption) by sending each descriptor over a UNIX socket closing it,

related to net/unix/af_unix.c and net/unix/garbage.c (bnc#839104).

- CVE-2016-7425: A buffer overflow in the Linux Kernel in

arcmsr_iop_message_xfer() could have caused kernel heap corruption and

arbitraty kernel code execution (bsc#999932)
