    Description

      CVE-2020-11996 Apache Tomcat HTTP/2 Denial of Service

      Severity: Important

      Vendor: The Apache Software Foundation

      Versions Affected:
      Apache Tomcat 10.0.0-M1 to 10.0.0-M5
      Apache Tomcat 9.0.0.M1 to 9.0.35
      Apache Tomcat 8.5.0 to 8.5.55

      Description:
      A specially crafted sequence of HTTP/2 requests could trigger high CPU
      usage for several seconds. If a sufficient number of such requests were
      made on concurrent HTTP/2 connections, the server could become unresponsive.

      Mitigation:

      • Upgrade to Apache Tomcat 10.0.0-M6 or later
      • Upgrade to Apache Tomcat 9.0.36 or later
      • Upgrade to Apache Tomcat 8.5.56 or later

      Credit:
      This issue was reported publicly via the Apache Tomcat Users mailing
      list without reference to the potential for DoS. The DoS risks were
      identified by the Apache Tomcat Security Team.
