RHEL 6 : kernel (RHSA-2014:2028)

high Nessus Plugin ID 80213

Language:

Synopsis

The remote Red Hat host is missing a security update for kernel.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2014:2028 advisory.

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

 * A flaw was found in the way the Linux kernel handled GS segment register base switching when recovering from a #SS (stack segment) fault on an erroneous return to user space. A local, unprivileged user could use this flaw to escalate their privileges on the system. (CVE-2014-9322, Important)

 Red Hat would like to thank Andy Lutomirski for reporting this issue.

 All kernel users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. The system must be rebooted for this update to take effect.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL kernel package based on the guidance in RHSA-2014:2028.
