Red Hat Security Advisory

 

Synopsis: Important: kernel security update

Advisory ID: RHSA-2016:0045-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2016-0045.html

Issue date: 2016-01-19

CVE Names: CVE-2015-5364 CVE-2015-5366

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

 

1. Summary:

 

Updated kernel packages that fix two security issues are now available for

Red Hat Enterprise Linux 5.

 

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

Red Hat Enterprise Linux Desktop (v. 5 client) - i386, noarch, x86_64

 

3. Description:

 

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

operating system.

 

* Two flaws were found in the way the Linux kernel's networking

implementation handled UDP packets with incorrect checksum values. A remote

attacker could potentially use these flaws to trigger an infinite loop in

the kernel, resulting in a denial of service on the system, or cause a

denial of service in applications using the edge triggered epoll

functionality. (CVE-2015-5364, CVE-2015-5366, Important)

 

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.

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

 

1239029 - CVE-2015-5366 CVE-2015-5364 kernel: net: incorrect processing of checksums in UDP implementation
