    value:
"* An integer overflow flaw was found in the way the Linux kernel's
netfilter connection tracking implementation loaded extensions. An
attacker on a local network could potentially send a sequence of
specially crafted packets that would initiate the loading of a large
number of extensions, causing the targeted system in that network to
crash. (CVE-2014-9715, Moderate)

* A stack-based buffer overflow flaw was found in the Linux kernel's
early load microcode functionality. On a system with UEFI Secure Boot
enabled, a local, privileged user could use this flaw to increase
their privileges to the kernel (ring0) level, bypassing intended
restrictions in place. (CVE-2015-2666, Moderate)

* It was found that the Linux kernel's ping socket implementation did
not properly handle socket unhashing during spurious disconnects,
which could lead to a use-after-free flaw. On x86-64 architecture
systems, a local user able to create ping sockets could use this flaw
to crash the system. On non-x86-64 architecture systems, a local user
able to create ping sockets could use this flaw to escalate their
privileges on the system. (CVE-2015-3636, Moderate)

* It was found that the Linux kernel's TCP/IP protocol suite
implementation for IPv6 allowed the Hop Limit value to be set to a
smaller value than the default one. An attacker on a local network
could use this flaw to prevent systems on that network from sending or
receiving network packets. (CVE-2015-2922, Low)

This update also fixes several bugs.

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