Red Hat Security Advisory

 

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

Advisory ID: RHSA-2016:1100-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2016-1100.html

Issue date: 2016-05-24

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

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

 

1. Summary:

 

An update for kernel is now available for Red Hat Enterprise Linux 6.6

Extended Update Support.

 

Red Hat Product Security has rated this update as having a security impact

of Important. A Common Vulnerability Scoring System (CVSS) base score,

which gives a detailed severity rating, is available for each vulnerability

from the CVE link(s) in the References section.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux HPC Node EUS (v. 6.6) - noarch, x86_64

Red Hat Enterprise Linux HPC Node Optional EUS (v. 6.6) - x86_64

Red Hat Enterprise Linux Server EUS (v. 6.6) - i386, noarch, ppc64, s390x, x86_64

Red Hat Enterprise Linux Server Optional EUS (v. 6.6) - i386, ppc64, s390x, x86_64

 

3. Description:

 

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

operating system.

 

Security Fix(es):

 

* 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)

 

Bug Fix(es):

 

* In anon_vma data structure, the degree counts number of child anon_vmas

and of VMAs that point to this anon_vma. In the unlink_anon_vma() function,

when its list is empty, anon_vma is going to be freed whether the external

refcount is zero or not, so the parent's degree should be decremented.

However, failure to decrement the degree triggered a BUG_ON() signal in

unlink_anon_vma(). The provided patch fixes this bug, and the degree is now

decremented as expected. (BZ#1326027)

 

Enhancement(s):

 

* The ixgbe NIC driver has been upgraded to upstream version 4.2.1, which

provides a number of bug fixes and enhancements over the previous version.

Notably:

 

NULL pointer crashes related to VLAN support have been fixed

 

Two more devices from the Intel X550 Ethernet controller family are now

supported: IDs 15AC and 15AD

 

Several PHY-related problems have been addressed: link disruptions and link

flapping

 

Added PHY-related support for Intel X550

 

System performance has been improved

 

(BZ#1315702)

 

4. Solution:

 

For details on how to apply this update, which includes the changes

described in this advisory, refer to:

 

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

 

The system must be rebooted for this update to take effect.

 

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

 

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