RHSA-2010:0964 - Security Advisory

Topic

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.

Description

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

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.
