How to fix?

Upgrade SLES:15.0 tomcat-lib to version 9.0.36-3.74.1 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.

While investigating bug 64830 it was discovered that Apache Tomcat 10.0.0-M1 to 10.0.0-M9, 9.0.0-M1 to 9.0.39 and 8.5.0 to 8.5.59 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.
