Several security vulnerabilities have been discovered in the Tomcat servlet and JSP engine. The version of Tomcat 8 in Jessie was only affected by CVE-2022-23181.

If Apache Tomcat was configured to ignore invalid HTTP headers via setting
rejectIllegalHeader to false (the default for 8.5.x only), Tomcat did not
reject a request containing an invalid Content-Length header making a
request smuggling attack possible if Tomcat was located behind a reverse
proxy that also failed to reject the request with the invalid header.

The fix for bug CVE-2020-9484 introduced a time of check, time of use
vulnerability into Apache Tomcat that allowed a local attacker to perform
actions with the privileges of the user that the Tomcat process is using.
This issue is only exploitable when Tomcat is configured to persist
sessions using the FileStore.

The documentation of Apache Tomcat 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.
