Synopsis

Moderate: Network observability 1.2.0 for Openshift

Type/Severity

Security Advisory: Moderate

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.

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 page(s) listed in the References section.
