Improper Input Validation vulnerability in Apache Tomcat. Incorrect error handling for some invalid HTTP priority headers resulted in incomplete clean-up of the failed request which created a memory leak. A large number of such requests could trigger an OutOfMemoryException resulting in a denial of service.

This issue affects Apache Tomcat: from 9.0.76 through 9.0.102, from 10.1.10 through 10.1.39, from 11.0.0-M2 through 11.0.5.
The following versions were EOL at the time the CVE was created but are 
known to be affected: 8.5.90 though 8.5.100.


Users are recommended to upgrade to version 9.0.104, 10.1.40 or 11.0.6 which fix the issue.

Apache Commons FileUpload before 1.5 does not limit the number of request parts to be processed resulting in the possibility of an attacker triggering a DoS with a malicious upload or series of uploads.




Note that, like all of the file upload limits, the
          new configuration option (FileUploadBase#setFileCountMax) is not
          enabled by default and must be explicitly configured.

Improper Neutralization of Escape, Meta, or Control Sequences vulnerability in Apache Tomcat. For a subset of unlikely rewrite rule configurations, it was possible 
for a specially crafted request to bypass some rewrite rules. If those 
rewrite rules effectively enforced security constraints, those 
constraints could be bypassed.

This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.5, from 10.1.0-M1 through 10.1.39, from 9.0.0.M1 through 9.0.102.
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 [FIXED_VERSION], which fixes the issue.
