(RHSA-2013:1185) Important: Red Hat JBoss Fuse 6.0.0 patch 2


Red Hat JBoss Fuse 6.0.0, based on Apache ServiceMix, provides an integration platform. Red Hat JBoss Fuse 6.0.0 patch 2 is an update to Red Hat JBoss Fuse 6.0.0 and includes bug fixes. Refer to the readme file included with the patch files for information about these fixes. The following security issues are also resolved with this update: A flaw was found in the logging performed during deserialization of the BrokerFactory class in Apache OpenJPA. A remote attacker able to supply a serialized instance of the BrokerFactory class, which will be deserialized on a server, could use this flaw to write an executable file to the server's file system. (CVE-2013-1768) A flaw in JRuby's JSON gem allowed remote attacks by creating different types of malicious objects. For example, it could initiate a denial of service attack through resource consumption by using a JSON document to create arbitrary Ruby symbols, which were never garbage collected. It could also be exploited to create internal objects which could allow a SQL injection attack. (CVE-2013-0269) It was discovered that JRuby's REXML library did not properly restrict XML entity expansion. An attacker could use this flaw to cause a denial of service by tricking a Ruby application using REXML to read text nodes from specially-crafted XML content, which will result in REXML consuming large amounts of system memory. (CVE-2013-1821) Note: Red Hat JBoss Fuse 6.0.0 ships JRuby as part of the camel-ruby component, which allows users to define Camel routes in Ruby. The default use of JRuby in Red Hat JBoss Fuse 6.0.0 does not appear to expose either CVE-2013-0269 or CVE-2013-1821. If the version of JRuby shipped with Red Hat JBoss Fuse 6.0.0 was used to build a custom application, then these flaws could be exposed. Multiple denial of service flaws were found in the way the Apache CXF StAX parser implementation processed certain XML files. If a web service utilized the StAX parser, a remote attacker could provide a specially-crafted XML file that, when processed, would lead to excessive CPU and memory consumption. (CVE-2013-2160) Red Hat would like to thank Ruby on Rails upstream for reporting CVE-2013-0269, and Andreas Falkenberg of SEC Consult Deutschland GmbH, and Christian Mainka, Juraj Somorovsky and Joerg Schwenk of Ruhr-University Bochum for reporting CVE-2013-2160. Upstream acknowledges Thomas Hollstegge of Zweitag and Ben Murphy as the original reporters of CVE-2013-0269. All users of Red Hat JBoss Fuse 6.0 as provided from the Red Hat Customer Portal are advised to apply this patch.
