CVE-2016-8745

Priority
Description
A bug in the error handling of the send file code for the NIO HTTP
connector in Apache Tomcat 9.0.0.M1 to 9.0.0.M13, 8.5.0 to 8.5.8, 8.0.0.RC1
to 8.0.39, 7.0.0 to 7.0.73 and 6.0.16 to 6.0.48 resulted in the current
Processor object being added to the Processor cache multiple times. This in
turn meant that the same Processor could be used for concurrent requests.
Sharing a Processor can result in information leakage between requests
including, not not limited to, session ID and the response body. The bug
was first noticed in 8.5.x onwards where it appears the refactoring of the
Connector code for 8.5.x onwards made it more likely that the bug was
observed. Initially it was thought that the 8.5.x refactoring introduced
the bug but further investigation has shown that the bug is present in all
currently supported Tomcat versions.
