Red Hat Security Advisory

 

Synopsis: Important: kernel security and bug fix update

Advisory ID: RHSA-2014:0432-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-0432.html

Issue date: 2014-04-24

CVE Names: CVE-2014-0101

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

 

1. Summary:

 

Updated kernel packages that fix one security issue and several bugs are

now available for Red Hat Enterprise Linux 6.4 Extended Update Support.

 

The Red Hat Security Response Team has rated this update as having

Important security impact. A Common Vulnerability Scoring System (CVSS)

base score, which gives a detailed severity rating, is available from the

CVE link in the References section.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux Compute Node Optional EUS (v. 6.4) - x86_64

Red Hat Enterprise Linux HPC Node EUS (v. 6.4) - noarch, x86_64

Red Hat Enterprise Linux Server EUS (v. 6.4) - i386, noarch, ppc64, s390x, x86_64

Red Hat Enterprise Linux Server Optional EUS (v. 6.4) - i386, ppc64, s390x, x86_64

 

3. Description:

 

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

operating system.

 

* A flaw was found in the way the Linux kernel processed an authenticated

COOKIE_ECHO chunk during the initialization of an SCTP connection. A remote

attacker could use this flaw to crash the system by initiating a specially

crafted SCTP handshake in order to trigger a NULL pointer dereference on

the system. (CVE-2014-0101, Important)

 

Red Hat would like to thank Nokia Siemens Networks for reporting this

issue.

 

This update also fixes several bugs. Documentation for these changes will

be available shortly from the Technical Notes document linked to in the

References section.

 

All kernel users are advised to 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 all previously released errata

relevant to your system have been applied.

 

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

Red Hat Network to apply this update are available at

https://access.redhat.com/site/articles/11258

 

To install kernel packages manually, use "rpm -ivh [package]". Do not use

"rpm -Uvh" as that will remove the running kernel binaries from your

system. You may use "rpm -e" to remove old kernels after determining that

the new kernel functions properly on your system.

 

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

 

1070705 - CVE-2014-0101 kernel: net: sctp: null pointer dereference when processing authenticated cookie_echo chunk
