Amazon Linux AMI : tomcat7 / tomcat8 (ALAS-2017-796)
Medium Nessus Plugin ID 97146
SynopsisThe remote Amazon Linux AMI 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 not limited to, session ID and the response body.
SolutionRun 'yum update tomcat7' to update your system.
Run 'yum update tomcat8' to update your system.
