CVE-2019-10072  (opens in a new tab)
CWE-667  (opens in a new tab)

How to fix?

Upgrade SLES:15.0 tomcat-lib to version 9.0.30-3.34.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream tomcat-lib package and not the tomcat-lib package as distributed by SLES. See How to fix? for SLES:15.0 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.
