<description>
|
|
<p>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.

<p>A remote attacker, by sending well-timed HTTP/2 requests, could possibly
|
|
obtain sensitive information.
