Descriptions

Incomplete Cleanup vulnerability in Apache Tomcat.When recycling various internal objects in Apache Tomcat from 11.0.0-M1 through 11.0.0-M11, from 10.1.0-M1 through 10.1.13, from 9.0.0-M1 through 9.0.80 and from 8.5.0 through 8.5.93, an error could
cause Tomcat to skip some parts of the recycling process leading to
information leaking from the current request/response to the next.

Users are recommended to upgrade to version 11.0.0-M12 onwards, 10.1.14 onwards, 9.0.81 onwards or 8.5.94 onwards, which fixes the issue.

Se recomienda a los usuarios actualizar a la versión 11.0.0-M12 en adelante, 10.1.14 en adelante, 9.0.81 en adelante o 8.5.94 en adelante, lo que soluciona el problema.

A flaw was found in Apache Tomcat. Tomcat may skip, after an error, the recycling of the internal objects that the next request/response process might use, resulting in information leaking from one request to the next. This flaw allows a malicious user to have access to this information.
