Affected Products:
openSUSE Leap 42.2
______________________________________________________________________________

An update that solves 5 vulnerabilities and has 32 fixes is
now available.

Description:

The openSUSE Leap 42.2 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 (in the kernel through 4.9) via a crafted ACPI
table (bnc#1049580).
– CVE-2017-14051: An integer overflow in the
qla2x00_sysfs_write_optrom_ctl function in
drivers/scsi/qla2xxx/qla_attr.c in the Linux kernel allowed local users
to cause a denial of service (memory corruption and system crash) by
leveraging root access (bnc#1056588).
– CVE-2017-12134: The xen_biovec_phys_mergeable function in
drivers/xen/biomerge.c in Xen might allow local OS guest users to
corrupt block device data streams and consequently obtain sensitive
memory information, cause a denial of service, or gain host OS
privileges by leveraging incorrect block IO merge-ability calculation
(bnc#1051790 1053919).
