CVE-2023-46589

Improper Input Validation vulnerability in Apache Tomcat.Tomcat from
11.0.0-M1 through 11.0.0-M10, from 10.1.0-M1 through 10.1.15, from 9.0.0-M1
through 9.0.82 and from 8.5.0 through 8.5.95 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. Users are
recommended to upgrade to version 11.0.0-M11 onwards, 10.1.16 onwards,
9.0.83 onwards or 8.5.96 onwards, which fix the issue.
