Red Hat Security Advisory

 

Synopsis: Important: kernel security and bug fix update

Advisory ID: RHSA-2010:0053-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2010-0053.html

Issue date: 2010-01-19

CVE Names: CVE-2007-4567 CVE-2009-4536 CVE-2009-4537

CVE-2009-4538

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

 

1. Summary:

 

Updated kernel packages that fix multiple security issues and two bugs are

now available for Red Hat Enterprise Linux 5.3 Extended Update Support.

 

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 (v. 5.3.z server) - i386, ia64, noarch, ppc, s390x, x86_64

 

3. Description:

 

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 IPv6 Extension Header (EH) handling

implementation in the Linux kernel. The skb->dst data structure was not

properly validated in the ipv6_hop_jumbo() function. This could possibly

lead to a remote denial of service. (CVE-2007-4567, Important)

 

* a flaw was found in each of the following Intel PRO/1000 Linux

drivers in the Linux kernel: e1000 and e1000e. A remote attacker using

packets larger than the MTU could bypass the existing fragment check,

resulting in partial, invalid frames being passed to the network stack.

These flaws could also possibly be used to trigger a remote denial of

service. (CVE-2009-4536, CVE-2009-4538, Important)

 

* a flaw was found in the Realtek r8169 Ethernet driver in the Linux

kernel. Receiving overly-long frames with a certain revision of the network

cards supported by this driver could possibly result in a remote denial of

service. (CVE-2009-4537, Important)

 

This update also fixes the following bugs:

 

* on certain hardware, the igb driver was unable to detect link statuses

correctly for Serializer-Deserializer (SERDES) interface Ethernet ports.

This may have caused problems for network interface bonding, such as

failover not occurring. (BZ#548023)

 

* in certain situations, kdump occasionally dumped a vmcore file with no

registers on Intel Itanium systems that were under high disk I/O load. In

these cases, this prevented the kernel stack backtrace in the vmcore from

being viewed with the crash utility. (BZ#542581)

 

Users should upgrade to these updated packages, which contain backported

patches to correct these issues. The system must be rebooted for this

update to take effect.

 

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

http://kbase.redhat.com/faq/docs/DOC-11259

 

5. Bugs fixed (http://bugzilla.redhat.com/):

 

542581 - kdump corefile cannot be backtraced in IA64 [rhel-5.3.z]

548023 - EL5.3: igb driver fails to detect link status change on SERDES interface [rhel-5.3.z]

548641 - CVE-2007-4567 kernel: ipv6_hop_jumbo remote system crash

550907 - CVE-2009-4537 kernel: r8169 issue reported at 26c3

551214 - CVE-2009-4538 kernel: e1000e frame fragment issue

552126 - CVE-2009-4536 kernel: e1000 issue reported at 26c3
