Debian DLA-779-1 : tomcat7 security update
Medium Nessus Plugin ID 96396
SynopsisThe remote Debian host is missing a security update.
DescriptionA 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.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
