+ <p>The payload length in a WebSocket frame was not correctly validated.
+ Invalid payload lengths could trigger an infinite loop. Multiple
requests
+ with invalid payload lengths could lead to a denial of service.</p>
+
+ <p>This was fixed with commit

+
+ <p>This issue was reported publicly via the Apache Bugzilla instance on 28
+ June 2020 and included references to high CPU but no specific reference
+ to denial of service. The associated DoS risks were identified by the
+ Apache Tomcat Security Team the same day. The issue was made public on
14
+ July 2020.</p>

+
+ <p>An h2c direct connection did not release the HTTP/1.1 processor after
the
+ upgrade to HTTP/2. If a sufficient number of such requests were made, an
+ OutOfMemoryException could occur leading to a denial of service.</p>
+
+ <p>This was fixed with commit
+ <a
href="https://github.com/apache/tomcat/commit/c9167ae30f3b03b112f3d81772e3450b7d0e6a25";>c9167ae3</a>.</p>
+
+ <p>This issue was reported publicly via the Apache Tomcat Users mailing
list
+ on 22 June 2020 without reference to the potential for DoS. After
further
+ discussion to identify the steps necessary to reproduce the issue, the
+ root cause of the issue and the associated DoS risks were identified by
+ the Apache Tomcat Security Team on 26 June 2020. The issue was made
+ public on 14 July 2020.</p>

+ <p><strong>Important: WebSocket DoS</strong>
+ <cve>CVE-2020-13935</cve></p>
+
+ <p>The payload length in a WebSocket frame was not correctly validated.
+ Invalid payload lengths could trigger an infinite loop. Multiple
requests
+ with invalid payload lengths could lead to a denial of service.</p>
+
+ <p>This was fixed with commit
+ <hashlink hash="40fa74c74822711ab878079d0a69f7357926723d"/>.</p>
+
+ <p>This issue was reported publicly via the Apache Bugzilla instance on 28
+ June 2020 and included references to high CPU but no specific reference
+ to denial of service. The associated DoS risks were identified by the
+ Apache Tomcat Security Team the same day. The issue was made public on
14
+ July 2020.</p>
+
+ <p>Affects: 9.0.0.M1 to 9.0.36</p>
+
+ <p><strong>Moderate: HTTP/2 DoS</strong>
+ <cve>CVE-2020-13934</cve></p>
+
+ <p>An h2c direct connection did not release the HTTP/1.1 processor after
the
+ upgrade to HTTP/2. If a sufficient number of such requests were made, an
+ OutOfMemoryException could occur leading to a denial of service.</p>
+
+ <p>This was fixed with commit
+ <hashlink hash="172977f04a5215128f1e278a688983dcd230f399"/>.</p>
+
+ <p>This issue was reported publicly via the Apache Tomcat Users mailing
list
+ on 22 June 2020 without reference to the potential for DoS. After
further
+ discussion to identify the steps necessary to reproduce the issue, the
+ root cause of the issue and the associated DoS risks were identified by
+ the Apache Tomcat Security Team on 26 June 2020. The issue was made
+ public on 14 July 2020.</p>
