Summary
Red Hat Security Advisory: openvswitch2.11 and ovn2.11 security update
Notes
Topic
An update for openvswitch2.11 and ovn2.11 is now available for Red Hat
OpenStack Platform 13 (Queens).
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.
Details
Open vSwitch provides standard network bridging functions and support for
the OpenFlow protocol for remote per-flow control of traffic.
OVN, the Open Virtual Network, is a system to support virtual network
abstraction. OVN complements the existing capabilities of OVS to add native support for virtual network abstractions, such as virtual L2 and L3 overlays and security groups.
Security Fix(es):
* buffer overflow in the lldp_decode function in daemon/protocols/lldp.c
(CVE-2015-8011)
* librte_vhost Integer overflow in vhost_user_set_log_base()
(CVE-2020-10722)
* librte_vhost Integer truncation in
vhost_user_check_and_alloc_queue_pair() (CVE-2020-10723)
* librte_vhost Missing inputs validation in Vhost-crypto (CVE-2020-10724)
For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page listed in the References section.
