Summary

The Fuse Management Console is used for managing Fuse ESB Enterprise and Fuse MQ Enterprise deployments.
This release of Fuse Management Console 7.1.0 serves as a replacement for Fuse Management Console 1.0.2, and includes bug fixes and enhancements. Refer to the Fuse Management Console 7.1.0 Release Notes for information on the most significant of these changes. The Release Notes will be available shortly from https://access.redhat.com/knowledge/docs/
The following security issue is also fixed with this release:
It was found that the Java hashCode() method implementation was susceptible to predictable hash collisions. A remote attacker could use this flaw to cause the Jetty HTTP server (a component of Apache Karaf, used by Fuse Management Console) to use an excessive amount of CPU time by sending an HTTP request with a large number of parameters whose names map to the same hash value. This update introduces a limit of 1000 on the number of parameters processed per request to mitigate this issue. (CVE-2011-4461)
Red Hat would like to thank oCERT for reporting this issue. oCERT acknowledges Julian Wälde and Alexander Klink as the original reporters.
All users of Fuse Management Console 1.0.2 as provided from the Red Hat Customer Portal are advised to upgrade to Fuse Management Console 7.1.0.
