Vulnerability from csaf_redhat - Published: 2020-05-26 15:11 - Updated: 2026-02-23 18:18Summary
Red Hat Security Advisory: openvswitch security, bug fix and enhancement update
Severity
Moderate
Notes
Topic: An update for openvswitch is now available in Fast Datapath for Red Hat Enterprise Linux 7.
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.
Details: Open vSwitch provides standard network bridging functions and support for the OpenFlow protocol for remote per-flow control of traffic.
Security Fix(es):
* dpdk: librte_vhost Interger overflow in vhost_user_set_log_base() (CVE-2020-10722)
* dpdk: librte_vhost Integer truncation in vhost_user_check_and_alloc_queue_pair() (CVE-2020-10723)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Bug Fix(es):
* OVS causing high pings and latency inside guest VM when an active DPDK port fails (BZ#1822198)
* SEGV after recirculation in batch processing in vswitchd 2.9.0 (BZ#1826886)

A vulnerability was found in DPDK versions 18.05 and above. A missing check for an integer overflow in vhost_user_set_log_base() could result in a smaller memory map than requested, possibly allowing memory corruption.
6.7 (Medium)
Vendor Fix

A memory corruption issue was found in DPDK versions 17.05 and above. This flaw is caused by an integer truncation on the index of a payload. Under certain circumstances, the index (a UInt) is copied and truncated into a uint16, which can lead to out of bound indexing and possible memory corruption.
