Descriptions
Improper Handling of Exceptional Conditions, Uncontrolled Resource Consumption vulnerability in Apache Tomcat. When processing an HTTP/2 stream, Tomcat did not handle some cases of excessive HTTP headers correctly. This led to a miscounting of active HTTP/2 streams which in turn led to the use of an incorrect infinite timeout which allowed connections to remain open which should have been closed.
This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.0-M20, from 10.1.0-M1 through 10.1.24, from 9.0.0-M1 through 9.0.89.
Users are recommended to upgrade to version 11.0.0-M21, 10.1.25 or 9.0.90, which fixes the issue.

Al procesar una secuencia HTTP/2, Tomcat no manejó correctamente algunos casos de encabezados HTTP excesivos. Esto llevó a un conteo erróneo de flujos HTTP/2 activos que a su vez llevó al uso de un tiempo de espera infinito incorrecto que permitió que las conexiones permanecieran abiertas y que deberían haberse cerrado.
