Red Hat Security Advisory

 

Synopsis: Important: kernel security and bug fix update

Advisory ID: RHSA-2008:0275-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2008-0275.html

Issue date: 2008-05-20

CVE Names: CVE-2007-5093 CVE-2007-6282 CVE-2007-6712

CVE-2008-1615

=====================================================================

 

1. Summary:

 

Updated kernel packages that fix various security issues and several bugs

are now available for Red Hat Enterprise Linux 5.

 

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 Desktop (v. 5 client) - i386, noarch, x86_64

Red Hat Enterprise Linux (v. 5 server) - i386, ia64, noarch, ppc, s390x, x86_64

 

3. Description:

 

The kernel packages contain the Linux kernel, the core of any Linux

operating system.

 

These updated packages fix the following security issues:

 

* on AMD64 architectures, the possibility of a kernel crash was discovered

by testing the Linux kernel process-trace ability. This could allow a local

unprivileged user to cause a denial of service (kernel crash).

(CVE-2008-1615, Important)

 

* on 64-bit architectures, the possibility of a timer-expiration value

overflow was found in the Linux kernel high-resolution timers

functionality, hrtimer. This could allow a local unprivileged user to setup

a large interval value, forcing the timer expiry value to become negative,

causing a denial of service (kernel hang). (CVE-2007-6712, Important)

 

* the possibility of a kernel crash was found in the Linux kernel IPsec

protocol implementation, due to improper handling of fragmented ESP

packets. When an attacker controlling an intermediate router fragmented

these packets into very small pieces, it would cause a kernel crash on the

receiving node during packet reassembly. (CVE-2007-6282, Important)

 

* a potential denial of service attack was discovered in the Linux kernel

PWC USB video driver. A local unprivileged user could use this flaw to

bring the kernel USB subsystem into the busy-waiting state, causing a

denial of service. (CVE-2007-5093, Low)

 

As well, these updated packages fix the following bugs:

 

* in certain situations, a kernel hang and a possible panic occurred when

disabling the cpufreq daemon. This may have prevented system reboots from

completing successfully.

 

* continual "softlockup" messages, which occurred on the guest's console

after a successful save and restore of a Red Hat Enterprise Linux 5

para-virtualized guest, have been resolved.

 

* in the previous kernel packages, the kernel may not have reclaimed NFS

locks after a system reboot.

 

Red Hat Enterprise Linux 5 users are advised to upgrade to these updated

packages, which contain backported patches to resolve these issues.

 

4. Solution:

 

Before applying this update, make sure that all previously-released

errata relevant to your system have been applied.

 

This update is available via Red Hat Network. Details on how to use

the Red Hat Network to apply this update are available at
