1. Summary:

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.

2. Description:

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
