MGASA-2017-0345 - Updated kernel packages fix security vulnerabilities

Publication date: 16 Sep 2017

CVE: CVE-2017-11600,

     CVE-2017-1000251

Description:
This kernel update is based on upstream 4.4.88 and fixes atleast the
following security issues:

net/xfrm/xfrm_policy.c in the Linux kernel through 4.12.3, when 
CONFIG_XFRM_MIGRATE is enabled, does not ensure that the dir value of
xfrm_userpolicy_id is XFRM_POLICY_MAX or less, which allows local users
to cause a denial of service (out-of-bounds access) or possibly have
unspecified other impact via an XFRM_MSG_MIGRATE xfrm Netlink message
(CVE-2017-11600).

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 (CVE-2017-12134 / XSA-229).

The XFS_IS_REALTIME_INODE macro in fs/xfs/xfs_linux.h in the Linux kernel
before 4.13.2 does not verify that a filesystem has a realtime device,
which allows local users to cause a denial of service (NULL pointer
dereference and OOPS) via vectors related to setting an RHINHERIT flag
on a directory (CVE-2017-14340).

The native Bluetooth stack in the Linux Kernel (BlueZ), starting at the
Linux kernel version 3.3-rc1 and up to and including 4.13.1, are vulnerable
to a stack overflow vulnerability in the processing of L2CAP configuration
responses resulting in Remote code execution in kernel space
(CVE-2017-1000251).

For other upstream fixes in this update, read the referenced changelogs.
