                   Red Hat Security Advisory

Synopsis:          Moderate: opendaylight security and bug fix update
Advisory ID:       RHSA-2018:2598-01
Product:           Red Hat Enterprise Linux OpenStack Platform
Advisory URL:      https://access.redhat.com/errata/RHSA-2018:2598
Issue date:        2018-08-29
CVE Names:         CVE-2018-10237
=====================================================================

1. Summary:

An update for OpenDaylight is now available for Red Hat OpenStack Platform
13.0 (Queens).

Red Hat Product Security has rated this update as having a security impact
of Moderate. 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 OpenStack Platform 13.0 - noarch

3. Description:

OpenDaylight (ODL) is a modular open platform for customizing and
automating networks of any size and scale. The OpenDaylight Project arose
out of the SDN movement, with a clear focus on network programmability.

Security Fix(es):

* guava: Unbounded memory allocation in AtomicDoubleArray and
CompoundOrdering classes allow remote attackers to cause a denial of
service (CVE-2018-10237)

For more details about the security issue(s), including the impact, a CVSS
score, and other related information, refer to the CVE page(s) listed in
the References section.

Bug Fix(es):

* Previously, when there are no DPNs associated with the controller, an
Invalid dpnId, for example, zero, was selected as the NAPT Switch. Since
the dpnId was zero, necessary flows for supporting external connectivity
for VMs were missing in the pipeline. So VMs were unable to connect to
internet.
Now, the Invalid dpnId is not chosen as an NAPT Switch and as soon as a new
DPN is associated with the OpenDaylight controller, it will schedule the
NAPT Switches for all the routers, that did not have the NAPT switch
scheduled.
As a result, VMs are now able to reach internet. (BZ#1597304)

* Some flows were missing from the ARP table and the flow programming
generated an error due to a missing group. As a result, L2 failed and
affected most of the traffic.
The flow programming now waits for the group to be added. The group is
always present and L2 traffic succeeds. (BZ#1598399)

* In OVS2.9, conntrack adds extra headers that the OpenFlow plugin cannot
parse. As a result, traffic from the VM to a PNF on external network
failed.
The extra headers are now explicit cleared. Traffic to PNF on external
network does not fail. (BZ#1600608)

* Some flows were missing from the SNAT table and the flow programming
generated an error due to a missing group. As a result, SNAT traffic from
compute, where the flow is missing,  failed and affected most of the
traffic.
As a result, the flow programming now waits for the group to be added.  The
group is always present and SNAT works. (BZ#1602404)

* Previously, the transaction did not close in
netvirt.vpnmanager.VpnOpStatusListener. This resulted in memory leaks at
scale and/or in longevity. This issue has been resolved and now
OpenDaylight requires less memory to run. (BZ#1607965)

* Previously, the transaction did not close in
netvirt.fibmanager.VrfEntryListener. This resulted in memory leaks at scale
and/or in longevity. This issue has been resolved and OpenDaylight now
requires less memory to run. (BZ#1585227)
