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

Red Hat Security Advisory

 

Synopsis: Moderate: kernel security, bug fix, and enhancement update

Advisory ID: RHSA-2015:1978-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2015-1978.html

Issue date: 2015-11-03

CVE Names: CVE-2014-8559 CVE-2015-5156

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

 

1. Summary:

 

Updated kernel packages that fix two security issues, several bugs, and add

one enhancement are now available for Red Hat Enterprise Linux 7.

 

Red Hat Product Security has rated this update as having Moderate 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 Client (v. 7) - noarch, x86_64

Red Hat Enterprise Linux Client Optional (v. 7) - x86_64

Red Hat Enterprise Linux ComputeNode (v. 7) - noarch, x86_64

Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64

Red Hat Enterprise Linux Server (v. 7) - noarch, ppc64, ppc64le, s390x, x86_64

Red Hat Enterprise Linux Server Optional (v. 7) - ppc64, ppc64le, s390x, x86_64

Red Hat Enterprise Linux Workstation (v. 7) - noarch, x86_64

Red Hat Enterprise Linux Workstation Optional (v. 7) - 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 VFS subsystem handled file

system locks. A local, unprivileged user could use this flaw to trigger a

deadlock in the kernel, causing a denial of service on the system.

(CVE-2014-8559, Moderate)

 

* A buffer overflow flaw was found in the way the Linux kernel's virtio-net

subsystem handled certain fraglists when the GRO (Generic Receive Offload)

functionality was enabled in a bridged network configuration. An attacker

on the local network could potentially use this flaw to crash the system,

or, although unlikely, elevate their privileges on the system.

(CVE-2015-5156, Moderate)

 

The CVE-2015-5156 issue was discovered by Jason Wang of Red Hat.

 

This update also fixes several bugs and adds one enhancement. Refer to the

following Knowledgebase article for further information:

 

https://access.redhat.com/articles/2039563

 

All kernel users are advised to upgrade to these updated packages, which

contain backported patches to correct these issues and add this

enhancement. 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.

 

For details on how to apply this update, refer to:

 

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

 

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

 

1159313 - CVE-2014-8559 kernel: fs: deadlock due to incorrect usage of rename_lock

1243852 - CVE-2015-5156 kernel: buffer overflow with fraglist larger than MAX_SKB_FRAGS + 2 in virtio-net
