Summary
Red Hat Security Advisory: openvswitch2.13 security, bug fix and enhancement update
Notes
Topic
An update for openvswitch2.13 is now available for Fast Datapath for Red Hat Enterprise Linux 8.
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.
Security Fix(es):
* dpdk: librte_vhost Malicious guest could cause segfault by sending invalid Virtio descriptor (CVE-2020-10725)
* 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)
* dpdk: librte_vhost Missing inputs validation in Vhost-crypto (CVE-2020-10724)
* dpdk: librte_vhost VHOST_USER_GET_INFLIGHT_FD message flooding to result in a DoS (CVE-2020-10726)
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):
* DPDK virtio_user lack of notifications make vhost_net+napi stops tx buffers (BZ#1803082)
* Update internal DPDK to 19.11.1 (BZ#1824825)
