Description

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

A denial of service flaw was found in the implementation of the
org.jboss.remoting.transport.socket.ServerThread class in JBoss Remoting.
An attacker could use this flaw to exhaust all available file descriptors
on the target server, preventing legitimate connections. Note that to
exploit this flaw remotely, the remoting port must be exposed directly or
indirectly (for example, deploying a public facing application that uses
JBoss Remoting could indirectly expose this flaw). (CVE-2013-4210)

This issue was discovered by James Livingston of the Red Hat Support
Engineering Group.
