+
+ <p>While investigating issue <a
href="https://bz.apache.org/bugzilla/show_bug.cgi?id=64830";>64830</a> it was
discovered that Apache
+ Tomcat could re-use an HTTP request header value from the previous
stream
+ received on an HTTP/2 connection for the request associated with the
+ subsequent stream. While this would most likely lead to an error and the
+ closure of the HTTP/2 connection, it is possible that information could
+ leak between requests.
+ </p>
+
+ <p>This was fixed with commit
+ <a

+ <p><strong>Moderate: HTTP/2 request header mix-up</strong>
+ <cve>CVE-2020-17527</cve></p>
+
+ <p>While investigating issue <bug>64830</bug> it was discovered that Apache
+ Tomcat could re-use an HTTP request header value from the previous
stream
+ received on an HTTP/2 connection for the request associated with the
+ subsequent stream. While this would most likely lead to an error and the
+ closure of the HTTP/2 connection, it is possible that information could
+ leak between requests.
+ </p>
+
+ <p>This was fixed with commit
+ <hashlink hash="d56293f816d6dc9e2b47107f208fa9e95db58c65"/>.</p>
+
+ <p>This issue was identified by the Apache Tomcat Security team on 10
+ November 2020. The issue was made public on 3 December 2020.</p>
+
+ <p>Affects: 9.0.0-M1 to 9.0.39</p>
