- In the Debian bugtracking system: Bug 895114, Bug 911786.

- More information:
Multiple vulnerabilities were discovered in libspring-java, a modular Java/J2EE application framework. An attacker may execute code, perform XST attack, issue unauthorized cross-domain requests or cause a DoS (Denial-of-Service) in specific configurations.
Spring Framework allows applications to expose STOMP over WebSocket endpoints with a simple, in-memory STOMP broker through the spring-messaging module. A malicious user (or attacker) can craft a message to the broker that can lead to a remote code execution attack.
Spring Framework allows web applications to change the HTTP request method to any HTTP method (including TRACE) using the HiddenHttpMethodFilter in Spring MVC. If an application has a pre-existing XSS vulnerability, a malicious user (or attacker) can use this filter to escalate to an XST (Cross Site Tracing) attack.
Spring Framework allows web applications to enable cross-domain requests via JSONP (JSON with Padding) through AbstractJsonpResponseBodyAdvice for REST controllers and MappingJackson2JsonView for browser requests. Both are not enabled by default in Spring Framework nor Spring Boot, however, when MappingJackson2JsonView is configured in an application, JSONP support is automatically ready to use through the
callbackJSONP parameters, enabling cross-domain requests.
Spring Framework provides support for range requests when serving static resources through the ResourceHttpRequestHandler, or starting in 5.0 when an annotated controller returns an org.springframework.core.io.Resource. A malicious user (or attacker) can add a range header with a high number of ranges, or with wide ranges that overlap, or both, for a denial of service attack.
For Debian 9 stretch, these problems have been fixed in version 4.3.5-1+deb9u1.
We recommend that you upgrade your libspring-java packages.
