Description

The Fuse Management Console is used for managing Fuse ESB Enterprise and
Fuse MQ Enterprise deployments.

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

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 Walde 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.
