Red Hat Security Advisory

Synopsis: Important: kernel security update
Advisory ID: RHSA-2005:808-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2005-808.html
Issue date: 2005-10-27
Updated on: 2005-10-27
Product: Red Hat Enterprise Linux
Obsoletes: RHSA-2005:514
CVE Names: CVE-2005-3053 CVE-2005-3108 CVE-2005-3110 CVE-2005-3119 CVE-2005-3180 CVE-2005-3181

1. Summary:

Updated kernel packages that fix several security issues and a page
attribute mapping bug are now available for Red Hat Enterprise Linux 4.

This update has been rated as having important security impact by the
Red Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, noarch, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, noarch, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, noarch, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, noarch, x86_64

3. Problem description:

The Linux kernel handles the basic functions of the operating system.

An issue was discovered that affects how page attributes are changed by the
kernel. Video drivers, which sometimes map kernel pages with a different
caching policy than write-back, are now expected to function correctly.
This change affects the x86, AMD64, and Intel EM64T architectures.

In addition the following security bugs were fixed:

The set_mempolicy system call did not check for negative numbers in the
policy field. An unprivileged local user could use this flaw to cause a
denial of service (system panic). (CVE-2005-3053)

A flaw in ioremap handling on AMD 64 and Intel EM64T systems. An
unprivileged local user could use this flaw to cause a denial of service or
minor information leak. (CVE-2005-3108)

A race condition in the ebtables netfilter module. On a SMP system that is
operating under a heavy load this flaw may allow remote attackers to cause
a denial of service (crash). (CVE-2005-3110)

A memory leak was found in key handling. An unprivileged local user could
use this flaw to cause a denial of service. (CVE-2005-3119)

A flaw in the Orinoco wireless driver. On systems running the vulnerable
drive, a remote attacker could send carefully crafted packets which would
divulge the contents of uninitialized kernel memory. (CVE-2005-3180)

A memory leak was found in the audit system. An unprivileged local user
could use this flaw to cause a denial of service. (CVE-2005-3181)

All Red Hat Enterprise Linux 4 users are advised to upgrade their kernels
to the packages associated with their machine architectures and
configurations as listed in this erratum.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied. Use Red Hat
Network to download and update your packages. To launch the Red Hat
Update Agent, use the following command:

up2date

For information on how to install packages manually, refer to the
following Web page for the System Administration or Customization
guide specific to your system:
