Updated kernel packages that fix two security issues are now available for
Red Hat Enterprise Linux 7.
The Red Hat Security Response Team has rated this update as having

* It was found that the Linux kernel's ptrace subsystem allowed a traced
process' instruction pointer to be set to a non-canonical memory address
without forcing the non-sysret code path when returning to user space.
A local, unprivileged user could use this flaw to crash the system or,
potentially, escalate their privileges on the system. (CVE-2014-4699,
Note: The CVE-2014-4699 issue only affected systems using an Intel CPU.
* A flaw was found in the way the pppol2tp_setsockopt() and
pppol2tp_getsockopt() functions in the Linux kernel's PPP over L2TP
implementation handled requests with a non-SOL_PPPOL2TP socket option
level. A local, unprivileged user could use this flaw to escalate their
privileges on the system. (CVE-2014-4943, Important)
Red Hat would like to thank Andy Lutomirski for reporting CVE-2014-4699,
and Sasha Levin for reporting CVE-2014-4943.
All kernel users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. The system must be
rebooted for this update to take effect.
