  - Denial of Service via incomplete cleanup vulnerability in Apache Tomcat. It was possible for WebSocket
    clients to keep WebSocket connections open leading to increased resource consumption.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. (CVE-2024-23672)

  - 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. (CVE-2024-24549)
