openSUSE Security Update : the Linux Kernel (openSUSE-2017-1063) (BlueBorne)

high Nessus Plugin ID 103288



The remote openSUSE host is missing a security update.


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).
