Synopsis: Important: kernel security and bug fix update

Advisory ID: RHSA-2014:0475-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-0475.html

Issue date: 2014-05-07

CVE Names: CVE-2013-6383 CVE-2014-0077 CVE-2014-2523

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

 

1. Summary:

 

Updated kernel packages that fix three security issues and several bugs are

now available for Red Hat Enterprise Linux 6.

 

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

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

scores, which give detailed severity ratings, are available for each

vulnerability from the CVE links in the References section.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux Desktop (v. 6) - i386, noarch, x86_64

Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64

Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, 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's netfilter connection

tracking implementation for Datagram Congestion Control Protocol (DCCP)

packets used the skb_header_pointer() function. A remote attacker could use

this flaw to send a specially crafted DCCP packet to crash the system or,

potentially, escalate their privileges on the system. (CVE-2014-2523,

Important)

 

* A flaw was found in the way the Linux kernel's Adaptec RAID controller

(aacraid) checked permissions of compat IOCTLs. A local attacker could use

this flaw to bypass intended security restrictions. (CVE-2013-6383,

Moderate)

 

* A flaw was found in the way the handle_rx() function handled large

network packets when mergeable buffers were disabled. A privileged guest

user could use this flaw to crash the host or corrupt QEMU process memory

on the host, which could potentially result in arbitrary code execution on

the host with the privileges of the QEMU process. (CVE-2014-0077, Moderate)

 

The CVE-2014-0077 issue was discovered by Michael S. Tsirkin of Red Hat.

 

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/):

 

1033530 - CVE-2013-6383 Kernel: AACRAID Driver compat IOCTL missing capability check

1064440 - CVE-2014-0077 kernel: vhost-net: insufficiency in handling of big packets in handle_rx()

1077343 - CVE-2014-2523 kernel: netfilter: nf_conntrack_dccp: incorrect skb_header_pointer API usages
