(RHSA-2012:1605) Moderate: Fuse MQ Enterprise 7.1.0 update

Fuse MQ Enterprise, based on Apache ActiveMQ, is a standards compliant
messaging system that is tailored for use in mission critical applications.

This release of Fuse MQ Enterprise 7.1.0 serves as a replacement for Fuse
MQ Enterprise 7.0.2, and includes bug fixes and enhancements. Refer to the
Fuse MQ Enterprise 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 MQ
Enterprise) 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 MQ Enterprise 7.0.2 as provided from the Red Hat Customer
Portal are advised to upgrade to Fuse MQ Enterprise 7.1.0.
