RHSA-2013:1028: Important: Fuse ESB Enterprise 7.1.0 update

Fuse ESB Enterprise, based on Apache ServiceMix, provides an integrationplatform.This release of Fuse ESB Enterprise 7.1.0 roll up patch 1 is an update toFuse ESB Enterprise 7.1.0 and includes bug fixes. Refer to the readme fileincluded with the patch files for information about the bug fixes.The following security issues are also fixed with this release:XML encryption backwards compatibility attacks were found against variousframeworks, including Apache CXF. An attacker could force a server to useinsecure, legacy cryptosystems, even when secure cryptosystems were enabledon endpoints. By forcing the use of legacy cryptosystems, flaws such asCVE-2011-1096 and CVE-2011-2487 would be exposed, allowing plain text to berecovered from cryptograms and symmetric keys. (CVE-2012-5575)Note: Automatic checks to prevent CVE-2012-5575 are only run whenWS-SecurityPolicy is used to enforce security requirements. It is bestpractice to use WS-SecurityPolicy to enforce security requirements.A flaw in JRuby's JSON gem allowed remote attacks by creating differenttypes of malicious objects. For example, it could initiate a denial ofservice attack through resource consumption by using a JSON document tocreate arbitrary Ruby symbols, which were never garbage collected. It couldalso be exploited to create internal objects which could allow a SQLinjection attack. (CVE-2013-0269)It was discovered that JRuby's REXML library did not properly restrict XMLentity expansion. An attacker could use this flaw to cause a denial ofservice by tricking a Ruby application using REXML to read text nodes fromspecially-crafted XML content, which will result in REXML consuming largeamounts of system memory. (CVE-2013-1821)Multiple denial of service flaws were found in the way the Apache CXFStAX parser implementation processed certain XML files. If a web serviceutilized the StAX parser, a remote attacker could provide aspecially-crafted XML file that, when processed, would lead to excessiveCPU and memory consumption. (CVE-2013-2160)Note: Fuse ESB Enterprise 7.1.0 ships JRuby as part of the camel-rubycomponent, which allows users to define Camel routes in Ruby. The defaultuse of JRuby in Fuse ESB Enterprise 7.1.0 does not appear to expose eitherCVE-2013-0269 or CVE-2013-1821. If the version of JRuby shipped with FuseESB Enterprise 7.1.0 was used to build a custom application, then theseflaws could be exposed.Red Hat would like to thank Tibor Jager, Kenneth G. Paterson and JurajSomorovsky of Ruhr-University Bochum for reporting CVE-2012-5575; Rubyon Rails upstream for reporting CVE-2013-0269; and Andreas Falkenberg ofSEC Consult Deutschland GmbH, and Christian Mainka, Juraj Somorovsky andJoerg Schwenk of Ruhr-University Bochum for reporting CVE-2013-2160.Upstream acknowledges Thomas Hollstegge of Zweitag and Ben Murphy as theoriginal reporters of CVE-2013-0269.All users of Fuse ESB Enterprise 7.1.0 as provided from the Red HatCustomer Portal are advised to upgrade to Fuse ESB Enterprise 7.1.0 roll uppatch 1.
