AI-suggested
A security update for Red Hat JBoss Enterprise Application Platform 8.0 is available and should be applied. The update includes patches for the ion-java StackOverflow vulnerability and the undertow Proxy Protocol parsing issue. Before applying the update, ensure all previously released errata are installed and back up all relevant data and configurations. Follow Red Hat's official guidance for applying the update as detailed in their documentation.
Description
A vulnerability was found in Undertow where the ProxyProtocolReadListener reuses the same StringBuilder instance across multiple requests. This issue occurs when the parseProxyProtocolV1 method processes multiple requests on the same HTTP connection. As a result, different requests may share the same StringBuilder instance, potentially leading to information leakage between requests or responses. In some cases, a value from a previous request or response may be erroneously reused, which could lead to unintended data exposure. This issue primarily results in errors and connection termination but creates a risk of data leakage in multi-request environments.
