+ <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
+ object was not reset between requests. This meant that once a
+ non-blocking I/O error occurred, all future requests handled by that
+ request object would fail. Users were able to trigger non-blocking I/O
+ errors, e.g. by dropping a connection, thereby creating the possibility
+ of triggering a DoS.</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>

+ <cve>CVE-2021-30639</cve></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
+ object was not reset between requests. This meant that once a
+ non-blocking I/O error occurred, all future requests handled by that
+ request object would fail. Users were able to trigger non-blocking I/O
+ errors, e.g. by dropping a connection, thereby creating the possibility
+ of triggering a DoS.</p>
+ <o>Applications that do not use non-blocking I/O are not exposed to this
+ vulnerability.</o>

+ <p>This was fixed with commit
