CVE-2024-34750 Apache Tomcat - Denial of Service
Severity: Important
Vendor: The Apache Software Foundation
Versions Affected:
Apache Tomcat 11.0.0-M1 to 11.0.0-M20
Apache Tomcat 10.1.0-M1 to 10.1.24
Apache Tomcat 9.0.0-M1 to 9.0.89
Description:
When processing an HTTP/2 stream, Tomcat did not handle some cases of
excessive HTTP headers correctly. This led to a miscounting of active
HTTP/2 streams which in turn led to the use of an incorrect infinite
timeout which allowed connections to remain open which should have been
closed.
Mitigation:
Users of the affected versions should apply one of the following
mitigations:
- Upgrade to Apache Tomcat 11.0.0-M21 or later
- Upgrade to Apache Tomcat 10.1.25 or later
- Upgrade to Apache Tomcat 9.0.90 or later
