An updated jboss-remoting package that fixes one security issue is now available for JBoss Enterprise Application Platform 4.3 for Red Hat Enterprise Linux 4 and 5. The Red Hat Security Response Team has rated this update as having low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.
JBoss Remoting is a framework for building distributed applications in Java. The JBoss Enterprise Application Platform 4.3.0.CP09 updates RHSA-2010:0937 and RHSA-2010:0938 did not, unlike the errata texts 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. Warning: Before applying this update, backup your existing JBoss Enterprise Application Platform installation (including all applications and configuration files). Users of JBoss Enterprise Application Platform 4.3 on Red Hat Enterprise Linux 4 and 5 should upgrade to this updated package, which contains a backported patch to correct this issue. The JBoss server process must be restarted for this update to take effect.
