NVD Description
Note: Versions mentioned in the description apply only to the upstream tomcat10 package and not the tomcat10 package as distributed by Ubuntu.
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.
