Описание

Incomplete cleanup vulnerability in Apache Tomcat allows a malformed request to potentially (depends on timing) cause one request from another user to fail. This issue affects Apache Tomcat: from 11.0.19 through 11.0.25, from 10.1.53 through 10.1.59, from 9.0.116 through 9.0.121. Users are recommended to upgrade to version 11.0.26, 10.1.60 or 9.0.122, which fix the issue.

A flaw was found in Apache Tomcat. An incomplete cleanup vulnerability allows a remote attacker to send a malformed HTTP/2 request. This can potentially cause a denial of service, leading to one request from another user failing.
