      CVE-2021-42340 Denial of Service

      Vendor: The Apache Software Foundation

      Versions Affected:

      Description:
      The fix for bug 63362 introduced a memory leak. The object introduced to collect metrics for HTTP upgrade connections was not released for WebSocket connections once the WebSocket connection was closed. This created a memory leak that, over time, could lead to a denial of service via an OutOfMemoryError.

      Mitigation:
      Users of the affected versions should apply one of the following
      mitigations:

      • Upgrade to Apache Tomcat 10.1.0-M6 or later
      • Upgrade to Apache Tomcat 10.0.12 or later
      • Upgrade to Apache Tomcat 9.0.54 or later
