RedHat: RHSA-2023-1817:01 Moderate: Network observability 1.2.0 for
Summary
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)
