Several security vulnerabilities have been discovered in the Tomcat
servlet and JSP engine.
CVE-2023-46589
Tomcat 9 did not correctly parse HTTP trailer headers. A trailer header
that exceeded the header size limit could cause Tomcat to treat a single
request as multiple requests leading to the possibility of request
smuggling when behind a reverse proxy.
CVE-2024-24549
Denial of Service due to improper input validation vulnerability for
HTTP/2. When processing an HTTP/2 request, if the request exceeded any of
the configured limits for headers, the associated HTTP/2 stream was not
reset until after all of the headers had been processed.
CVE-2024-23672
Denial of Service via incomplete cleanup vulnerability. It was possible
for WebSocket clients to keep WebSocket connections open leading to
increased resource consumption.
