Important: Request smuggling CVE-2023-45648

Tomcat did not correctly parse HTTP trailer headers. A specially crafted, invalid trailer header could cause Tomcat to treat a single request as multiple requests leading to the possibility of request smuggling when behind a reverse proxy.

This was fixed with commit 8ecff306.

This issue was reported to the Tomcat Security Team on 12 September 2023. The issue was made public on 10 October 2023.

Affects: 10.1.0-M1 to 10.1.13

Important: Denial of Service CVE-2023-44487

Tomcat’s HTTP/2 implementation was vulnerable to the rapid reset attack. The denial of service typically manifested as an OutOfMemoryError.

This was fixed with commit 76bb4bfb.

This issue was reported to the Tomcat Security Team on 14 September 2023. The issue was made public on 10 October 2023.

Affects: 10.1.0-M1 to 10.1.13

Important: Information Disclosure CVE-2023-42795

When recycling various internal objects, including the request and the response, prior to re-use by the next request/response, an error could cause Tomcat to skip some parts of the recycling process leading to information leaking from the current request/response to the next.

This was fixed with commit 9375d671.

This issue was identified by the Tomcat Security Team on 13 September 2023. The issue was made public on 10 October 2023.

Affects: 10.1.0-M1 to 10.1.13
