______________________________________________________________________________

An update that solves 24 vulnerabilities and has 56 fixes
is now available.

Description:

The SUSE Linux Enterprise 12 rt-kernel was updated to 3.12.69 to receive
various security and bugfixes.

The following security bugs were fixed:

– CVE-2015-8962: Fixed a double free vulnerability in the SCSI subsystem
that allowed local users to gain privileges or cause a denial of service
(memory corruption and system crash) (bnc#1010501).

allowed local users to gain privileges or cause a denial of service
(use-after-free) (bnc#1010502).

properly restrict write operations in situations where the KERNEL_DS
option is set, which allowed local users to read or write to arbitrary
kernel memory locations or cause a denial of service (use-after-free)
(bnc#1017710).

truncation, which allowed local users to cause a denial of service
(system crash) (bnc#1009969).
