A flaw was found in the tomcat package. When a web application sends a WebSocket message concurrently with the WebSocket connection closing, the application may continue to use the socket after it has been closed. In this case, the error handling triggered could cause the pooled object to be placed in the pool twice. This issue results in subsequent connections using the same object concurrently, which causes data to be potentially returned to the wrong user or application stability issues. (CVE-2022-25762)
The documentation of Apache Tomcat 10.1.0-M1 to 10.1.0-M14, 10.0.0-M1 to 10.0.20, 9.0.13 to 9.0.62 and 8.5.38 to 8.5.78 for the EncryptInterceptor incorrectly stated it enabled Tomcat clustering to run over an untrusted network. This was not correct. While the EncryptInterceptor does provide confidentiality and integrity protection, it does not protect against all risks associated with running over any untrusted network, particularly DoS risks. (CVE-2022-29885)
