Hi,

The following vulnerability was published for tomcat9.

CVE-2019-10072[0]:
| The fix for CVE-2019-0199 was incomplete and did not address HTTP/2
| connection window exhaustion on write in Apache Tomcat versions
| 9.0.0.M1 to 9.0.19 and 8.5.0 to 8.5.40 . By not sending WINDOW_UPDATE
| messages for the connection window (stream 0) clients were able to
| cause server-side threads to block eventually leading to thread
| exhaustion and a DoS.

If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
