Affected Products:
openSUSE Leap 42.3
______________________________________________________________________________

An update that solves three vulnerabilities and has 25
fixes is now available.

Description:

The openSUSE Leap 42.3 kernel was updated to 4.4.87 to receive various
security and bugfixes.

The following security bugs were fixed:

– CVE-2017-1000251: The native Bluetooth stack in the Linux Kernel (BlueZ)
was vulnerable to a stack overflow vulnerability in the processing of
L2CAP configuration responses resulting in Remote code execution in
kernel space (bnc#1057389).
– CVE-2017-14106: The tcp_disconnect function in net/ipv4/tcp.c in the
Linux kernel allowed local users to cause a denial of service
(__tcp_select_window divide-by-zero error and system crash) by
triggering a disconnect within a certain tcp_recvmsg code path
(bnc#1056982).
– CVE-2017-11472: The acpi_ns_terminate() function in
drivers/acpi/acpica/nsutils.c in the Linux kernel did not flush the
operand cache and causes a kernel stack dump, which allowed local users
to obtain sensitive information from kernel memory and bypass the KASLR
protection mechanism via a crafted ACPI table (bnc#1049580).
