  script_tag(name:"insight", value:"This kernel-linus update is based on upstream -longterm 3.14.23 and
fixes the following security issues:

The kvm_iommu_map_pages function in virt/kvm/iommu.c in the Linux
kernel through 3.16.1 miscalculates the number of pages during the
handling of a mapping failure, which allows guest OS users to (1)
cause a denial of service (host OS memory corruption) or possibly
have unspecified other impact by triggering a large gfn value or
(2) cause a denial of service (host OS memory consumption) by
triggering a small gfn value that leads to permanently pinned
pages (CVE-2014-3601).

The assoc_array_gc function in the associative-array implementation
in lib/assoc_array.c in the Linux kernel before 3.16.3 does not
properly implement garbage collection, which allows local users to
cause a denial of service (NULL pointer dereference and system
crash) or possibly have unspecified other impact via multiple
'keyctl newring' operations followed by a 'keyctl timeout'
operation (CVE-2014-3631).

The xfs_da3_fixhashpath function in fs/xfs/xfs_da_btree.c in the
xfs implementation in the Linux kernel before 3.14.2 does not properly
compare btree hash values, which allows local users to cause a denial
of service (filesystem corruption, and OOPS or panic) via operations
on directories that have hash collisions, as demonstrated by rmdir
operations (CVE-2014-7283).

The net_get_random_once implementation in net/core/utils.c in the
Linux kernel 3.13.x and 3.14.x before 3.14.5 on certain Intel processors
does not perform the intended slow-path operation to initialize random
seeds, which makes it easier for remote attackers to spoof or disrupt IP
communication by leveraging the predictability of TCP sequence numbers,
TCP and UDP port numbers, and IP ID values (CVE-2014-7284)

The pivot_root implementation in fs/namespace.c in the Linux kernel
through 3.17 does not properly interact with certain locations of
a chroot directory, which allows local users to cause a denial of
service (mount-tree loop) via . (dot) values in both arguments to
the pivot_root system call (CVE-2014-7970).

The do_umount function in fs/namespace.c in the Linux kernel
through 3.17 does not require the CAP_SYS_ADMIN capability for
do_remount_sb calls that change the root filesystem to read-only,
which allows local users to cause a denial of service (loss of
writability) by making certain unshare system calls, clearing the
/ MNT_LOCKED flag, and making an MNT_FORCE umount system call
(CVE-2014-7975).
