    value:
"* A flaw was found in the way seunshare, a utility for running
executables under a different security context, used the capng_lock
functionality of the libcap-ng library. The subsequent invocation of
suid root binaries that relied on the fact that the setuid() system
call, among others, also sets the saved set-user-ID when dropping the
binaries' process privileges, could allow a local, unprivileged user
to potentially escalate their privileges on the system. Note: the fix
for this issue is the kernel part of the overall fix, and introduces
the PR_SET_NO_NEW_PRIVS functionality and the related SELinux exec
transitions support. (CVE-2014-3215, Important)

* A use-after-free flaw was found in the way the Linux kernel's SCTP
implementation handled authentication key reference counting during
INIT collisions. A remote attacker could use this flaw to crash the
system or, potentially, escalate their privileges on the system.
(CVE-2015-1421, Important)

* It was found that the Linux kernel's KVM implementation did not
ensure that the host CR4 control register value remained unchanged
across VM entries on the same virtual CPU. A local, unprivileged user
could use this flaw to cause a denial of service on the system.
(CVE-2014-3690, Moderate)

* An out-of-bounds memory access flaw was found in the syscall tracing
functionality of the Linux kernel's perf subsystem. A local,
unprivileged user could use this flaw to crash the system.
(CVE-2014-7825, Moderate)

* An out-of-bounds memory access flaw was found in the syscall tracing
functionality of the Linux kernel's ftrace subsystem. On a system with
ftrace syscall tracing enabled, a local, unprivileged user could use
this flaw to crash the system, or escalate their privileges.
(CVE-2014-7826, Moderate)

* It was found that the Linux kernel memory resource controller's
(memcg) handling of OOM (out of memory) conditions could lead to
deadlocks. An attacker able to continuously spawn new processes within
a single memory- constrained cgroup during an OOM event could use this
flaw to lock up the system. (CVE-2014-8171, Moderate)

* A race condition flaw was found in the way the Linux kernel keys
management subsystem performed key garbage collection. A local
attacker could attempt accessing a key while it was being garbage
collected, which would cause the system to crash. (CVE-2014-9529,
Moderate)

* A stack-based buffer overflow flaw was found in the
TechnoTrend/Hauppauge DEC USB device driver. A local user with write
access to the corresponding device could use this flaw to crash the
kernel or, potentially, elevate their privileges on the system.
(CVE-2014-8884, Low)

* An information leak flaw was found in the way the Linux kernel's
ISO9660 file system implementation accessed data on an ISO9660 image
with RockRidge Extension Reference (ER) records. An attacker with
physical access to the system could use this flaw to disclose up to
255 bytes of kernel memory. (CVE-2014-9584, Low)

The system must be rebooted for this update to take effect."
