Improper Resource Shutdown or Release vulnerability in Apache Tomcat.

If an error occurred (including exceeding limits) during the processing of a multipart upload, temporary copies of the uploaded parts written to disc were not cleaned up immediately but left for the garbage collection process to delete. Depending on JVM settings, application memory usage and application load, it was possible that space for the temporary copies of uploaded parts would be filled faster than GC cleared it, leading to a DoS.



This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.11, from 10.1.0-M1 through 10.1.46, from 9.0.0.M1 through 9.0.109.

The following versions were EOL at the time the CVE was created but are 
known to be affected: 8.5.0 though 8.5.100. Other, older, EOL versions may also be affected.
Users are recommended to upgrade to version 11.0.12 or later, 10.1.47 or later or 9.0.110 or later which fixes the issue.

Improper Input Validation vulnerability.

This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.14, from 10.1.0-M1 through 10.1.49, from 9.0.0-M1 through 9.0.112.

The following versions were EOL at the time the CVE was created but are 
known to be affected: 8.5.0 through 8.5.100. Older EOL versions are not affected.
Tomcat did not validate that the host name provided via the SNI 
extension was the same as the host name provided in the HTTP host header 
field. If Tomcat was configured with more than one virtual host and the 
TLS configuration for one of those hosts did not require client 
certificate authentication but another one did, it was possible for a 
client to bypass the client certificate authentication by sending 
different host names in the SNI extension and the HTTP host header field.



The vulnerability only applies if client certificate authentication is 
only enforced at the Connector. It does not apply if client certificate 
authentication is enforced at the web application.


Users are recommended to upgrade to version 11.0.15 or later, 10.1.50 or later or 9.0.113 or later, which fix the issue.

Improper Input Validation vulnerability in Apache Tomcat.


Tomcat did not limit HTTP/0.9 requests to the GET method. If a security 
constraint was configured to allow HEAD requests to a URI but deny GET 
requests, the user could bypass that constraint on GET requests by 
sending a (specification invalid) HEAD request using HTTP/0.9.


This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.14, from 10.1.0-M1 through 10.1.49, from 9.0.0.M1 through 9.0.112.


Older, EOL versions are also affected.

Users are recommended to upgrade to version 11.0.15 or later, 10.1.50 or later or 9.0.113 or later, which fixes the issue.
