NVD Description

Note: Versions mentioned in the description apply only to the upstream eap7-apache-cxf-rt package and not the eap7-apache-cxf-rt package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.
