Red Hat Security Advisory: Red Hat support for Spring Boot 2.7.17 security update

Notes

Topic
An update is now available for Red Hat OpenShift Application Runtimes. Red Hat Product Security has rated this update as having a security impact of Important. 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
Red Hat support for Spring Boot provides an application platform that reduces the complexity of developing and operating applications (monoliths and microservices) for OpenShift as a containerized platform. This release of Red Hat support for Spring Boot 2.7.17 serves as a replacement for Red Hat support for Spring Boot 2.7.16, and includes security, bug fixes and enhancements. For more information, see the release notes linked in the References section. Security Fix(es): * undertow: HTTP/2: Multiple HTTP/2 enabled web servers are vulnerable to a DDoS attack (Rapid Reset Attack) (CVE-2023-44487) A Red Hat Security Bulletin which addresses further details about the Rapid Reset flaw is available in the References section. * apache-johnzon: Prevent inefficient internal conversion from BigDecimal at large scale (CVE-2023-33008) 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.

Several package specific mitigations are also available. \n     a. nginx: https://www.nginx.com/blog/http-2-rapid-reset-attack-impacting-f5-nginx-products/\n     b. netty: https://github.com/netty/netty/security/advisories/GHSA-xpw8-rcwv-8f8p\n     c. haproxy: https://www.haproxy.com/blog/haproxy-is-not-affected-by-the-http-2-rapid-reset-attack-cve-2023-44487\n     d. nghttp2: https://github.com/nghttp2/nghttp2/security/advisories/GHSA-vx74-f528-fxqg\n     e. golang: The default stream concurrency limit in golang is 250 streams (requests) per HTTP/2 connection. This value may be adjusted in the golang.org/x/net/http2 package using the Server.MaxConcurrentStreams setting and the ConfigureServer function which are available in golang.org/x/net/http2.",
