Test ID:1.3.6.1.4.1.25623.1.0.71412
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2012:0862
Summary:NOSUMMARY
Description:Description:
The remote host is missing updates announced in
advisory RHSA-2012:0862.

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

This update fixes the following security issues:

* 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)

* A malicious Network File System version 4 (NFSv4) server could return a
crafted reply to a GETACL request, causing a denial of service on the
client. (CVE-2011-4131, Moderate)

Red Hat would like to thank Nelson Elhage for reporting CVE-2011-1083, and
Andy Adamson for reporting CVE-2011-4131.

This update also fixes several hundred bugs and adds enhancements. Refer to
the Red Hat Enterprise Linux 6.3 Release Notes for information on the most
significant of these changes, and the Technical Notes for further
information, both linked to in the References.

All Red Hat Enterprise Linux 6 users are advised to install these updated
packages, which correct these issues, and fix the bugs and add the
enhancements noted in the Red Hat Enterprise Linux 6.3 Release Notes and
Technical Notes. The system must be rebooted for this update to take
