+ <p>Apache Tomcat did not correctly parse the HTTP transfer-encoding request
+ header in some circumstances leading to the possibility of request
+ smuggling when used with a reverse proxy. Specifically: Tomcat
+ incorrectly ignored the transfer-encoding header if the client declared
+ it would only accept an HTTP/1.0 response; Tomcat honoured the identify

+ encoding was the final encoding.</p>

+ <p>An error introduced as part of a change to improve error handling during

+
+ <p>Apache Tomcat did not correctly parse the HTTP transfer-encoding request
+ header in some circumstances leading to the possibility of request
+ smuggling when used with a reverse proxy. Specifically: Tomcat
+ incorrectly ignored the transfer-encoding header if the client declared
+ it would only accept an HTTP/1.0 response; Tomcat honoured the identify
+ encoding; and Tomcat did not ensure that, if present, the chunked
+ encoding was the final encoding.</p>

+
+ <p>An error introduced as part of a change to improve error handling during
+ non-blocking I/O meant that the error flag associated with the Request

+ <p><strong>Important: Request Smuggling</strong>
+ <cve>CVE-2021-33037</cve></p>
+
+ <p>Apache Tomcat did not correctly parse the HTTP transfer-encoding request
+ header in some circumstances leading to the possibility of request
+ smuggling when used with a reverse proxy. Specifically: Tomcat
+ incorrectly ignored the transfer-encoding header if the client declared
+ it would only accept an HTTP/1.0 response; Tomcat honoured the identify
+ encoding; and Tomcat did not ensure that, if present, the chunked
+ encoding was the final encoding.</p>
+
+ <p>This was fixed with commits
+ <hashlink hash="45d70a86a901cbd534f8f570bed2aec9f7f7b88e"/>,
