(RHSA-2012:0150) Moderate: Red Hat Enterprise Linux 5.8 kernel update

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.
