Description

JBoss Remoting is a framework for building distributed applications in
Java.

Hat Customer Portal did not, unlike the RHSA-2010:0939 erratum text stated,
provide a fix for CVE-2010-3862. A remote attacker could use
specially-crafted input to cause the JBoss Remoting listeners to become
unresponsive, resulting in a denial of service condition for services
communicating via JBoss Remoting sockets. (CVE-2010-4265)

Red Hat would like to thank Ole Husgaard of eXerp.com for reporting this
issue.
