The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 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 Wälde and Alexander Klink as the original reporters.
