CVE-2016-8745 Apache Tomcat Information Disclosure Severity: Important Vendor: The Apache Software Foundation Versions Affected: Apache Tomcat 9.0.0.M1 to 9.0.0.M13 Apache Tomcat 8.5.0 to 8.5.8 Earlier versions are not affected. Description The refactoring of the Connector code for 8.5.x onwards introduced a regression in the error handling of the send file code for the NIO HTTP connector. An error during send file processing 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. Mitigation Users of the NIO HTTP connector with the affected versions should apply one of the following mitigations - Switch to the NIO2 HTTP or APR HTTP connector - Disable send file - Upgrade to Apache Tomcat 9.0.0.M15 or later (Apache Tomcat 9.0.0.M14 has the fix but was not released) - Upgrade to Apache Tomcat 8.5.9 or later Credit: This issue was reported publicly as Bug 60409 [1] and the security implications identified by the Tomcat security team.

We already have v8.5.9 in tree. Because this branch was never stable and no stable branch was affected, no need for stabilization at all. @ Maintainer(s): Please cleanup 8.5.x and 9.0.x branch.
Upstream updated the adivsory, and added the following affected versions: - Apache Tomcat 8.0.0.RC1 to 8.0.39 (new) - Apache Tomcat 7.0.0 to 7.0.73 (new) - Apache Tomcat 6.0.16 to 6.0.48 (new) Full updated advisory (from http://www.openwall.com/lists/oss-security/2017/01/05/3): CVE-2016-8745 Apache Tomcat Information Disclosure Severity: Important Vendor: The Apache Software Foundation Versions Affected: Apache Tomcat 9.0.0.M1 to 9.0.0.M13 Apache Tomcat 8.5.0 to 8.5.8 Apache Tomcat 8.0.0.RC1 to 8.0.39 (new) Apache Tomcat 7.0.0 to 7.0.73 (new) Apache Tomcat 6.0.16 to 6.0.48 (new) Description A bug in the error handling of the send file code for the NIO HTTP connector 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. Mitigation: Users of the NIO HTTP connector with the affected versions should apply one of the following mitigations - Switch to the BIO HTTP, NIO2 HTTP or APR HTTP connector - Disable send file - Upgrade to Apache Tomcat 9.0.0.M15 or later (Apache Tomcat 9.0.0.M14 has the fix but was not released) - Upgrade to Apache Tomcat 8.5.9 or later - Upgrade to Apache Tomcat 8.0.40 or later when released - Upgrade to Apache Tomcat 7.0.74 or later when released - Upgrade to Apache Tomcat 6.0.49 or later when released Credit: This issue was reported publicly as Bug 60409 [1] and the security implications identified by the Tomcat security team.
