Summary
Red Hat Security Advisory: OpenShift Virtualization 4.9.0 RPMs security and bug fix update

Notes

Topic
Red Hat OpenShift Virtualization release 4.9.0 is now available with updates to packages and images that fix several bugs and add enhancements. 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
OpenShift Virtualization is Red Hat's virtualization solution designed for Red Hat OpenShift Container Platform. This advisory contains OpenShift Virtualization 4.9.0 RPMs. Security Fix(es): * golang: data race in certain net/http servers including ReverseProxy can lead to DoS (CVE-2020-15586) * golang: ReadUvarint and ReadVarint can read an unlimited number of bytes from invalid inputs (CVE-2020-16845) * golang: crypto/elliptic: incorrect operations on the P-224 curve (CVE-2021-3114) * golang: net/http: panic in ReadRequest and ReadResponse when reading a very large header (CVE-2021-31525) 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.

It is possible for components that make client connections to malicious servers to be exploited, however the maximum impact is a crash. This vulnerability is rated Low for the following components: \n* OpenShift Container Platform\n* OpenShift Virtualization \n* OpenShift ServiceMesh\n* OpenShift distributed tracing components.",
