CVE-2023-34055

In Spring Boot versions 2.7.0 - 2.7.17, 3.0.0-3.0.12 and 3.1.0-3.1.5, it is possible for a user to provide specially crafted HTTP requests that may cause a denial-of-service (DoS) condition.

Specifically, an application is vulnerable when all of the following are true:

• the application uses Spring MVC or Spring WebFlux
• org.springframework.boot:spring-boot-actuator is on the classpath

Red Hat does not ship any spring integration in the RHEL log4j package, therefore the log4j package is not affected by this issue in Red Hat Enterprise Linux 8 & 9.

Red Hat Single Sign-On provides Spring Boot adapters, but does not provide the affected code and is not affected by this flaw.
