A flaw was found in the Apache Tomcat, where 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. It affects the version of Apache Tomcat 10.0.0-M1 to 10.0.0-M6, Apache Tomcat 9.0.0.M1 to 9.0.36, Apache Tomcat 8.5.0 to 8.5.56, and Apache Tomcat 7.0.27 to 7.0.104.

This vulnerability is out of security support scope for the following product: * Red Hat JBoss Data Virtualization 6 Please refer to https://access.redhat.com/support/policy/updates/jboss_notes for more details.
This vulnerability is out of security support scope for the following products: * Red Hat Enterprise Application Platform 6 * Red Hat Data Grid 6 Please refer to https://access.redhat.com/support/policy/updates/jboss_notes for more details.
Red Hat Jboss Fuse 6 ships some of the vulnerable artifacts as bundled artifacts in ops4j pax web, however there is no use of these artifacts in Fuse itself, the artifacts are also prevented from loading with a deny list in karaf, for these reasons we believe the impact upon Fuse 6.3 is low. This vulnerability is out of security support scope for the following products: * Red Hat JBoss Fuse 6 Please refer to https://access.redhat.com/support/policy/updates/jboss_notes for more details.
This vulnerability is out of security support scope for the following product: * Red Hat Software Collections Common Java Packages Please see https://access.redhat.com/support/policy/updates/rhscl and https://access.redhat.com/support/policy/updates/rhscl-rhel7 for more details
Red Hat OpenStack Platform 13 is affected as it ships tomcat-embed-websockets 8.0.46, which does not include the check for `payloadLength < 0` in `processRemainingHeader()`.
Mitigation: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Changing OpenStack Platform 13 to affected/wontfix as we ship the vulnerable code but it is not used by default.

This bug is now closed. Further updates for individual products will be reflected on the CVE page(s): https://access.redhat.com/security/cve/cve-2020-13935
Statement: Red Hat Certificate System 10.0 as well as Red Hat Enterprise Linux 8's Identity Management, are using a vulnerable version of Tomcat, bundled into the pki-servlet-engine component. However, there are no entry point for WebSockets, and thus it is not possible to trigger the flaw in a supported setup. A future update may fix the code. Similarly, Red Hat OpenStack Platform 13 does not ship with websocket functionality enabled by default.
