Description OSIDB Bzimport 2025-07-10 20:02:17 UTC 
Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') vulnerability in Apache Tomcat when using the APR/Native connector. This was particularly noticeable with client initiated closes of HTTP/2 connections.

This issue affects Apache Tomcat: from 9.0.0.M1 through 9.0.106.

Users are recommended to upgrade to version 9.0.107, which fixes the issue.
