"text": "This vulnerability in Apache Tomcat is of significant importance due to its potential to exploit HTTP request smuggling, presenting a security risk for web applications utilizing Tomcat. The flaw arises from Tomcat\u0027s improper parsing of HTTP trailer headers, where a specifically crafted header exceeding the size limit could cause Tomcat to treat a single request as multiple ones. This opens the door for attackers to manipulate requests and potentially conduct various malicious activities, such as unauthorized access, data exposure, or other exploits, particularly when Tomcat is deployed behind a reverse proxy. \n\nThe pki-servlet-engine package has been obsoleted by the Tomcat package. Therefore, this issue will be fixed in the Tomcat package rather than the pki-serlvet-engine package. Please follow the RHEL Tomcat trackers instead for the updates.",
