Summary:	NOSUMMARY
Description:	Description: The remote host is missing updates announced in advisory RHSA-2012:0150. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issue: * A flaw was found in the way the Linux kernel's Event Poll (epoll) subsystem handled large, nested epoll structures. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2011-1083, Moderate) Red Hat would like to thank Nelson Elhage for reporting this issue. These updated kernel packages include a number of bug fixes and enhancements. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 5.8 Technical Notes, linked to in the References, for information on the most significant of these changes. All Red Hat Enterprise Linux 5 users are advised to install these updated packages, which correct these issues and add these enhancements. The system must be rebooted for this update to take effect. Solution: Please note that this update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date http://rhn.redhat.com/errata/RHSA-2012-0150.html Risk factor : Medium
