Summary
Red Hat Security Advisory: Fuse ESB Enterprise 7.1.0 update

Notes

Topic
Fuse ESB Enterprise 7.1.0, which fixes two security issues, various bugs, and adds enhancements, is now available from the Red Hat Customer Portal. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.
Details
Fuse ESB Enterprise, based on Apache ServiceMix, provides an integration platform. This release of Fuse ESB Enterprise 7.1.0 serves as a replacement for Fuse ESB Enterprise 7.0.2, and includes bug fixes and enhancements. Refer to the Fuse ESB 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 issues are 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 ESB 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) A denial of service flaw was found in the implementation of associative arrays (hashes) in JRuby. An attacker able to supply a large number of inputs to a JRuby application (such as HTTP POST request parameters sent to a web application) that are used as keys when inserting data into an array could trigger multiple hash function collisions, making array operations take an excessive amount of CPU time. To mitigate this issue, the Murmur hash function has been replaced with the Perl hash function. (CVE-2012-5370) Note: Fuse ESB Enterprise 7.0.2 ships JRuby as part of the camel-ruby component, which allows users to define Camel routes in Ruby. The default use of JRuby in Fuse ESB Enterprise 7.0.2 does not appear to expose this flaw. If the version of JRuby shipped with Fuse ESB Enterprise 7.0.2 was used to build a custom application, then this flaw could be exposed. Red Hat would like to thank oCERT for reporting CVE-2011-4461. oCERT acknowledges Julian Walde and Alexander Klink as the original reporters of CVE-2011-4461. All users of Fuse ESB Enterprise 7.0.2 as provided from the Red Hat Customer Portal are advised to upgrade to Fuse ESB Enterprise 7.1.0.
