Doc Type: If docs needed, set a value
Doc Text:
A vulnerability was found in the Tomcat package due to its handling of HTTP/2 requests. Specifically, when an HTTP/2 request surpasses the predetermined limits for headers configured within the server, the associated HTTP/2 stream isn't reset immediately. Instead, the reset action occurs only after all the headers within the request have been processed. This lapse in resetting the stream exposes the system to potential risks, as it allows malicious actors to exploit the delay in stream reset to carry out various attacks, such as header manipulation or resource exhaustion.

Description Zack Miele 2024-03-14 20:59:53 UTC
Denial of Service due to improper input validation vulnerability for HTTP/2 requests in Apache Tomcat. When processing an HTTP/2 request, if the request exceeded any of the configured limits for headers, the associated HTTP/2 stream was not reset until after all of the headers had been processed.This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.0-M16, from 10.1.0-M1 through 10.1.18, from 9.0.0-M1 through 9.0.85, from 8.5.0 through 8.5.98.

Users are recommended to upgrade to version 11.0.0-M17, 10.1.19, 9.0.86 or 8.5.99 which fix the issue.
