Summary
Apache Tomcat: DoS via malformed HTTP/2 PRIORITY_UPDATE frame
Details

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.
