Test ID:1.3.6.1.4.1.25623.1.0.871214
Category:Red Hat Local Security Checks
Title:RedHat Update for kernel RHSA-2014:0923-01
Summary:The remote host is missing an update for the 'kernel'; package(s) announced via the referenced advisory.
Description:Summary:
The remote host is missing an update for the 'kernel'
package(s) announced via the referenced advisory.

Vulnerability Insight:
The kernel packages contain the Linux kernel, the core of any Linux
operating system.

* It was found that the Linux kernel's ptrace subsystem allowed a traced
process's 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,
Important)

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.

Affected Software/OS:
kernel on Red Hat Enterprise Linux Server (v. 7)

Solution:
Please Install the Updated Packages.
