Summary
Red Hat Security Advisory: Run Once Duration Override Operator for Red Hat OpenShift 1.1.0 for RHEL 9

Notes

Topic
An update for run-once-duration-override-container, run-once-duration-override-operator-bundle-container, and run-once-duration-override-operator-container is now available for RODOO-1.1-RHEL-9. 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
The Run Once Duration Override Operator for Red Hat OpenShift is an optional operator that makes it possible to override activeDeadlineSecondsOverride field during pod admission. Security Fix(es): * golang: net/http, x/net/http2: rapid stream resets can cause excessive work (CVE-2023-44487) (CVE-2023-39325) * HTTP/2: Multiple HTTP/2 enabled web servers are vulnerable to a DDoS attack (Rapid Reset Attack) (CVE-2023-44487) * golang: net/http/internal: Denial of Service (DoS) via Resource Consumption via HTTP requests (CVE-2023-39326) * golang: crypto/tls: Timing Side Channel attack in RSA based TLS key exchanges. (CVE-2023-45287) 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.

Although the vulnerability exposes a Timing Side Channel, potentially allowing information retrieval through RSA-based TLS key exchanges, its exploitation demands significant access and expertise. Additionally, while earlier versions implemented RSA blinding to counter timing attacks, the removal of PKCS#1 padding may still leak timing data. However, the practicality of exploiting this flaw is limited, and the transition to a fully constant time RSA implementation in Go 1.20 significantly bolsters security, reducing the risk posed by timing side channels.",
