  script_tag(name:"insight", value:"This kernel-linus update is based on upstream -longterm 3.10.58 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 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).

For other fixes included in this update, read the referenced
changelogs.");
