Package : tomcat7 Version : 7.0.28-4+deb7u9 CVE ID : CVE-2016-8745 Debian Bug : 849949
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 limited to, session ID and the response body.
In addition this update also addresses a regression when running Tomcat 7 with SecurityManager enabled due to an incomplete fix for CVE-2016-6816.
For Debian 7 "Wheezy", these problems have been fixed in version 7.0.28-4+deb7u9.
We recommend that you upgrade your tomcat7 packages.
