Red Hat has issued an update for JBoss Fuse
Red Hat JBoss Fuse 6.x
This fixes multiple vulnerabilities, which can be exploited by malicious people to bypass certain security restrictions and cause a DoS.
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.
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.
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.
