Summary
Red Hat Security Advisory: Network observability 1.2.0 for Openshift

Notes

Topic
Network Observability 1.2.0 for OpenShift 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
Network Observability 1.2.0 is an OpenShift operator that provides a monitoring pipeline to collect and enrich network flows that are produced by the Network observability eBPF agent. The operator provides dashboards, metrics, and keeps flows accessible in a queryable log store, Grafana Loki. When a FlowCollector is deployed, new dashboards are available in the Console. This update contains bug fixes. Security Fix(es): * golang: net/http: An attacker can cause excessive memory growth in a Go server accepting HTTP/2 requests (CVE-2022-41717) * golang: crypto/tls: large handshake records may cause panics (CVE-2022-41724) * golang: net/http, mime/multipart: denial of service from excessive resource consumption (CVE-2022-41725) 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.
