CVE-2019-10072 (opens in a new tab)How to fix?
Upgrade RHEL:8 jws5-tomcat to version 0:9.0.21-10.redhat_4.1.el8jws or higher.
This issue was patched in RHSA-2019:3929.
NVD Description
Note: Versions mentioned in the description apply only to the upstream jws5-tomcat package and not the jws5-tomcat package as distributed by RHEL.
See How to fix? for RHEL:8 relevant fixed versions and status.
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.
